News & Research:

  • Antioxidants and Dementia Risk: Consideration through a Cerebrovascular Perspective - Nutrients. 2016 Dec 20;8(12) - "An emerging body of evidence suggests that the integrity of the cerebrovascular blood-brain barrier (BBB) is centrally involved in the onset and progression of cognitive impairment and dementia ... Conclusively, there is a compelling body of evidence that suggest antioxidants may prevent cognitive decline and dementia by protecting the integrity and function of BBB and, indeed, further studies are needed to directly examine these effects in addition to underlying molecular mechanisms" - See Garden of Life Vitamin Code 50 & Wiser Men's Multi, 240 Capsules and Garden of Life Vitamin Code 50 & Wiser Women's Multi, 240 Capsules.
  • Fountain of youth? Dietary supplement may prevent and reverse severe damage to aging brain, research suggests - Science Daily, 6/2/16 - "contains common ingredients such as vitamins B, C and D, folic acid, green tea extract, cod liver oil and other nutraceuticals ... The mice used in this study had widespread loss of more than half of their brain cells, severely impacting multiple regions of the brain by one year of age, the human equivalent of severe Alzheimer's disease ... they also discovered that the mice on the supplements experienced enhancement in vision and most remarkably in the sense of smell -- the loss of which is often associated with neurological disease -- improved balance and motor activity"
  • Scientific secrets for successful aging? - Science Daily, 3/29/16 - "Now that these age-related metabolites have been identified, the decline in antioxidants and muscle strength suggest that it is important for individuals to consume foods high in antioxidants and to continue exercising, especially after the age of 65. This could help increase the levels of the related metabolites in the body and improve body conditions"
  • Top 3 Foods for a Longer Life - ABC News, 4/21/14 - "resveratrol increases the activity of specific genes called sirtuins that protect against diseases of aging by revving up the mitochondria, the little batteries inside our cells ... mice fed the bacterial strain Bifidobacterium animalis lactis lived longer and were healthier than mice that did not receive the probiotic ... people who consume 650 mg a day of polyphenols live longer than those who get less then that" - See resveratrol products at Amazon.com and Garden of Life, Radical Fruits Antioxidant Complex at Amazon.com.
  • The effect of multivitamin/mineral supplements on age-related cataracts: a systematic review and meta-analysis - Nutrients. 2014 Feb 28;6(3):931-49 - "we searched multiple databases to identify relevant studies including both cohort studies and randomized controlled trials (RCTs) ... Pooled results from the cohort studies indicated that multivitamin/mineral supplements have a significant beneficial effect in decreasing the risk of nuclear cataracts (RR: 0.73; 95% CI: 0.64-0.82), cortical cataracts (RR: 0.81; 95% CI: 0.68-0.94), and any cataracts (RR: 0.66; 95% CI: 0.39-0.93)" - See Garden of Life, Vitamin Code, 50 & Wiser Men at Amazon.com and Garden of Life, Vitamin Code, 50 & Wiser Women at Amazon.com.
  • Nutritional supplement improves cognitive performance in older adults, study finds - Science Daily, 2/6/14 - "The USF-developed nutritional supplement, containing extracts from blueberries and green tea combined with vitamin D3 and amino acids, including carnosine, was tested by the USF researchers in a clinical trial enrolling 105 healthy adults, ages 65 to 85 ... called NT-020 ... Those randomized to the group of 52 volunteers receiving NT-020 demonstrated improvements in cognitive processing speed, while the 53 volunteers randomized to receive a placebo did not ... Blueberries, a major ingredient in the NT-020 formula, are rich in polyphenols ... NT-020 is 95 percent polyphenols" - See Garden of Life, Radical Fruits Antioxidant Complex at Amazon.com and carnosine products at Amazon.com.
  • Fresh faced: Looking younger for longer - Science Daily, 1/10/14 - "While UVB radiation easily causes sunburn, UVA radiation penetrates deeper, damaging our DNA by generating free radicals which degrades the collagen that gives skin its elastic quality ... the most potent anti-oxidants were those that targeted the batteries of the skin cells, known as the mitochondria. They compared these mitochondrial-targeted anti-oxidants to other non-specific antioxidants such as resveratrol, found in red wine, and curcumin found in curries, that target the entire cell. They found that the most potent mitochondrial targeted anti-oxidant was Tiron which provided 100%, protection of the skin cell against UVA sun damage and the release of damaging enzymes causing stress-induced damage ... Tiron is not a naturally occurring compound and has not yet been tested for toxicity in humans although there have been a few studies on rats ... Antioxidants in our diets from green tea, resveratrol which is found in red wine, turmeric which is used in curries and lycopene found in tomatoes, as well as some components in cosmetic creams, are known to neutralise this damage within the cells. They can slow down the damage and the rate of aging and potentially lower the rate of other sun-induced skin lesions ... Resveratrol, the antioxidant found in red wine, was found to protect against 22% of both the ultraviolet A radiation and stress-induced damage. NAC, a frequently used laboratory-based anti-oxidant, offered 20% protection against oxidative stress and 8% against UVA and curcumin offered 16% protection against oxidative stress and 8% against UVA" - See resveratrol products at Amazon.com, n-acetyl cysteine at Amazon.com and curcumin products at Amazon.com.
  • Misleading News on Multivitamins: How Media Missed the Value of Supplements - U.S. News, 12/30/13 - "These news headlines (headlines like "Are Multivitamins a Waste of Money?," "Vitamins Should Be Avoided" and "Your Multivitamins aren't Doing a D**n Thing" ) and even the editorial in one of medicines leading journals – the Annals of Internal Medicine – do mislead unless you are a fine-print reader. And the news headlines did not mention the fine print ... What the fine print said were that all those people in these studies had normal nutrition and had no vitamin deficiencies, were not potentially or actually pregnant and weren't tested for quality-of-life issues like eyesight. And the news media ignored the significant 8 percent reduction in non-prostate cancers for men over 50, significant 18 percent reduction in non-prostate cancers for men over 70 and the non-significant (because they didn't study enough people) 11 percent reduction in cardiovascular events and deaths (of a high-dose vitamin regimen compared with a low-dose one – yes, everyone in that study received vitamin supplementation)."
  • Multivitamins With Minerals May Protect Older Women With Invasive Breast Cancer - Science Daily, 10/9/13 - "The research was conducted as part of the Women's Health Initiative Clinical Trials and the Women's Health Initiative(WHI)Observational Study. Combined, the two studies include data from 161,608 postmenopausal women ages 50 to 79 when they first joined the study ... A comparison of mortality rates revealed that women with invasive breast cancer who took multivitamin/mineral supplements were 30 percent less likely to die from their cancers than women with invasive breast cancer who hadn't taken the supplements. Could differences between the multivitamin/mineral users and nonusers account for this finding? The researchers looked at many possible confounding factors including additional supplements that the women took, their smoking status, education, race/ethnicity, weight, depression, alcohol use, physical activity, age at breast cancer diagnosis, and diabetes. The association between regular use of multivitamin/mineral supplements and reduced risk of death persisted even after these factors were taken into account" - See Garden of Life, Vitamin Code, 50 & Wiser Women at Amazon.com.
  • Nutrient Supplementation - Medscape, 9/25/13 - "men taking antioxidants had a statistically significant increase in both live birth rates and pregnancy rates. For those undergoing assisted reproduction, the odds ratio that antioxidant use would improve pregnancy rates was 4.18, with a 4.85-fold improvement in live birth rate also noted" - See Garden of Life, Radical Fruits Antioxidant Complex at Amazon.com and Garden of Life, Vitamin Code, 50 & Wiser Men at Amazon.com.
  • More Evidence Berries Have Health-Promoting Properties - Science Daily, 4/21/13 - "researchers from the Human Nutrition Research Center on Aging at Tufts University and University of Maryland Baltimore County recently fed rats a berry diet for 2 months and then looked at their brains after irradiation, a model for accelerated aging ... Berries seem to promote autophagy, the brain's natural housekeeping mechanism, thereby reducing the toxic accumulation"
  • Optimism Linked to Higher Antioxidant Levels - Medscape, 1/15/13 - "for every standard deviation increase in optimism, there was an increase in carotenoid concentrations of 3% to 13% in age-adjusted models ... Antioxidants are good examples of positive functioning because they help to inhibit other molecules from producing free radicals that damage cells and contribute to disease ... Although optimism was associated with an increase in carotenoids, they also found a link to increased levels of vitamin E ... we can't conclusively determine whether optimism leads to healthier levels of antioxidants or vice versa" - See Garden of Life, Radical Fruits Antioxidant Complex at Amazon.com.
  • Antioxidants may ease peripheral arterial disease (PAD) blood pressure increase, study suggests - Science Daily, 11/8/12 - "Low antioxidant levels contribute to increased blood pressure during exercise for people with peripheral arterial disease ... Antioxidants prevent the reactive oxygen species from damaging cells ... "This indicates that during normal, everyday activities such as walking, an impaired antioxidant system -- as well as other factors -- plays a role in the increased blood pressure response to exercise," Muller said. "Therefore, supplementing the diet with antioxidants may help these patients, but more studies are needed to confirm this concept."" - See Garden of Life, Radical Fruits Antioxidant Complex at Amazon.com.
  • Diet high in total antioxidants associated with lower risk of myocardial infarction in women - Science Daily, 9/21/12 - "a diet rich in antioxidants, mainly from fruits and vegetables, can significantly reduce the risk of myocardial infarction ... Total antioxidant capacity measures in a single value all antioxidants present in diet and the synergistic effects between them ... followed 32,561 Swedish women aged 49-83 from September 1997 through December 2007 ... The women were categorized into five groups of total antioxidant capacity of diet ... Women in the group with the highest total antioxidant capacity had a 20% lower risk, and they consumed almost 7 servings per day of fruit and vegetables, which was nearly 3 times more than the women with the least antioxidant capacity, who on average consumed 2.4 servings"
  • Dietary Antioxidants May Keep Dementia at Bay - Medscape, 9/19/12 - "Dietary antioxidants, specifically vitamin C and beta-carotene, may protect older adults against dementia ... evaluated serum levels of vitamin C, vitamin E, beta-carotene, lycopene, and coenzyme Q10 in 74 adults with mild dementia (Mini–Mental State Examination score of 24 or lower) and 158 cognitively healthy age- and sex-matched control participants. The average age of study participants was 78.9 years ... those with dementia had significantly lower blood vitamin C and beta-carotene levels"
  • Iron, vitamins could affect physical fitness in adolescents - Science Daily, 8/9/12 - "Because nutrition and fitness are intertwined -- for example, iron forms part of hemoglobin, which carries oxygen to muscles, and antioxidants such as vitamin C aid in rebuilding damage after intense training -- these two findings could be related. In a new study, researchers have found that adolescents' blood levels of various micronutrients are correlated with how well they performed in certain physical fitness tests. Though these results don't prove causality, they suggest a new relationship between different measures of adolescent health ... The researchers found that blood levels of certain micronutrients were intimately connected with the volunteers' performance on the physical fitness tests. For cardiorespiratory fitness, concentrations of hemoglobin, retinol, and vitamin C in males and beta-carotene and vitamin D in females was associated with VO2max. For muscular fitness, concentrations of hemoglobin, beta-carotene, retinol, and alpha-tocopherol in males and beta-carotene and vitamin D in females was associated with performing better on the standing long jump test"
  • Insulin Resistance and Adiposity in Relation to Serum β-Carotene Levels - J Pediatr. 2012 Jul;161(1):58-64.e2 - "To determine the effects of placebo vs an encapsulated supplement of fruit and vegetable juice concentrate (FVJC) on serum β-carotene levels, insulin resistance, adiposity, and subclinical inflammation in boys ... Thirty age-matched prepubertal boys (9 lean and 21 overweight (OW); age range, 6-10 years) were studied ... A 6-month supplementation with FVJC in the presence of nutritional counseling was associated with an increase in serum β-carotene concentrations and a reduction in adiposity in conjunction with an improvement in insulin resistance in OW boys" - See Garden of Life, Radical Fruits Antioxidant Complex at Amazon.com.
  • Do Fruits and Veggies Make You More Attractive? - WebMD, 3/7/12 - "changes in the redness and yellowness of skin in white people may be linked to the number of servings of fruit and vegetables they eat on a daily basis. These antioxidant-rich foods, which are loaded with plant-based pigments, seem to affect skin tone ... They suggest it's the carotenoids -- the red, yellow, and orange pigments in fruits and vegetables -- that play an important role in skin tone. Foods such as carrots, sweet potatoes, squash, and apricots are rich in beta-carotene, as are some dark green vegetables, including spinach and kale ... Another carotenoid is lycopene, which is found in tomatoes and pink grapefruits" - See Jarrow Formulas, CarotenALL at Amazon.com and Garden of Life, Radical Fruits Antioxidant Complex at Amazon.com.
  • Antioxidant spices, like turmeric and cinnamon, reduce negative effects of high-fat meal - Science Daily, 8/10/11 - "Normally, when you eat a high-fat meal, you end up with high levels of triglycerides, a type of fat, in your blood ... If this happens too frequently, or if triglyceride levels are raised too much, your risk of heart disease is increased. We found that adding spices to a high-fat meal reduced triglyceride response by about 30 percent, compared to a similar meal with no spices added ... Antioxidants, like spices, may be important in reducing oxidative stress and thus reducing the risk of chronic disease"
  • Reduction of circulating superoxide dismutase activity in type 2 diabetic patients with microalbuminuria and its modulation by telmisartan therapy - Hypertens Res. 2011 Aug 4 - "Interestingly, the telmisartan treatment not only reduced the circulating levels of two oxidative stress markers, 8-hydroxy-2'-deoxyguanosine (8-OHdG) and nitrotyrosine (NT), but also enhanced serum SOD activity. Notably, a significant correlation was observed between the increase in serum SOD activity and the reduction in albuminuria. We further compared the anti-oxidative effect of telmisartan with that of losartan, another member of the ARB class, by implementing an 8-week interval crossover treatment with these ARBs in another 12 microalbuminuric type 2 diabetic patients. The patients showed higher serum SOD activity, and lower circulating levels of 8-OHdG and NT, during treatment with telmisartan than with losartan. These results suggest that telmisartan has a more potent antioxidative effect through its ability to enhance SOD activity in type 2 diabetic patients with microalbuminuria" - See telmisartan at OffshoreRx1.com.
  • Antioxidants of growing interest to address infertility, erectile dysfunction - Science Daily, 7/28/11 - "A growing body of evidence suggests that antioxidants may have significant value in addressing infertility issues in both women and men, including erectile dysfunction, and researchers say that large, specific clinical studies are merited to determine how much they could help ... Some commonly used antioxidants, such as vitamins C and E, could help, Hagen said. But others, such as lipoic acid, are a little more cutting-edge and set up a biological chain reaction that has a more sustained impact on vasomotor function and health ... Polyphenols, the phytochemicals that often give vegetables their intense color and are also found in chocolate and tea, are also of considerable interest"
  • A novel and potent antioxidant found in tomato plants, initial results suggest - Science Daily, 7/22/11 - "A team of researchers from the Institute of Molecular and Cell Biology (IBMCP) -a joint centre of the Universitat Politècnica de València and CSIC, the Spanish National Research Council- have identified a novel and potent natural antioxidant occurring in tomato plants. It is a phenolic substance that is synthesised by the tomato plant when it is subjected to biotic stress. Until now, it was completely unknown ... The UPV and CSIC have registered the national and international patents of the new antioxidant and the laboratory procedures used to isolate and synthesise it chemically ... the antioxidant power of the new compound is much higher -14 times higher, to be precise- than, for example, that of resveratrol, a well-known antioxidant, found in red wine, which can delay cellular aging. In addition, it is 4.5 times more potent than vitamin E and 10 times more potent than vitamin C" - Note:  The patent thing makes you wonder if the claims are overblown though.
  • High Antioxidant Intake May Lower Risk for Early AMD - Medscape, 6/14/11 - "We assessed the intake of antioxidants, zinc, and ω-3 fatty acids in daily foods, diagnosed the onset of early AMD during a lengthy follow-up, and investigated the risk-reducing effect of these nutrients in the various genotypes of CFH [complement factor H] Y402H and LOC387715 A69S ... Median follow-up duration was 8.6 years ... There appeared to be a possible biological interaction between the CFH Y402H genotype and intakes of zinc, β-carotene, lutein/zeaxanthin, and eicosapentaenoic/docosahexaenoic acid (EPA/DHA), and between the LOC387715 A69S genotype and zinc and EPA/DHA, based on significant synergy indices ... High dietary intake of nutrients with antioxidant properties reduces the risk of early AMD in those at high genetic risk"
  • How vitamins and minerals may prevent age-related diseases - Science Daily, 5/31/11 - "Severe deficiency of the vitamins and minerals required for life is relatively uncommon in developed nations, but modest deficiency is very common and often not taken seriously. A new research published online in the FASEB Journal, however, may change this thinking as it examines moderate selenium and vitamin K deficiency to show how damage accumulates over time as a result of vitamin and mineral loss, leading to age-related diseases ... If the principles of the theory, as demonstrated for vitamin K and selenium, can be generalized to other vitamins and minerals, this may provide the foundation needed ... They discovered a highly sophisticated array of mechanisms at cellular and tissue levels that, when selenium is limited, protect essential selenium-dependent proteins at the expense of those that are nonessential. They also found that mutations in selenium-dependent proteins that are lost on modest selenium deficiency result in characteristics shared by age-related diseases including cancer, heart disease, and loss of immune or brain function"
  • Naturally occurring plant alkaloids could slow down Alzheimer's disease, study suggests - Science Daily, 5/26/11 - "Beta-carboline alkaloids could potentially be used in therapeutic drugs to stop, or at least slow down, the progressively debilitating effects of Alzheimer's ... Beta-carboline alkaloids are found in a number of medicinal plants. They have antioxidant properties, and have been shown to protect brain cells from excessive stimulation of neurotransmitters. "(They) are natural occurring compounds in some plant species that affect multiple central nervous system targets,""
  • Antioxidant formula prior to radiation exposure may prevent DNA injury, trial suggests - Science Daily, 3/29/11 - "In what the researchers say is the first clinical trial of its kind, as much as a 50 percent reduction in DNA injury was observed after administering the formula prior to CT scans"
  • Antioxidants may improve chances of conceiving in male subfertility - Science Daily, 1/18/11 - "Compared to controls, a couple was more likely to have a pregnancy or live birth if the man took antioxidants"
  • Eating berries may activate the brain's natural housekeeper for healthy aging - Science Daily, 8/23/10 - "berries, and possibly walnuts, activate the brain's natural "housekeeper" mechanism, which cleans up and recycles toxic proteins linked to age-related memory loss and other mental decline ... natural compounds called polyphenolics found in fruits, vegetables and nuts have an antioxidant and anti-inflammatory effect that may protect against age-associated decline"
  • Dietary Antioxidant and Mineral Intake in Humans Is Associated with Reduced Risk of Esophageal Adenocarcinoma but Not Reflux Esophagitis or Barrett' Esophagus - J Nutr. 2010 Aug 11 - "We found that overall antioxidant index, a measure of the combined intake of vitamin C, vitamin E, total carotenoids, and selenium, was associated with a reduced risk of EAC [odds ratio (OR) = 0.57; 95% CI = 0.33-0.98], but not BE (OR = 0.95; 95% CI = 0.53-1.71) or RE (OR = 1.60; 95% CI = 0.86-2.98), for those in the highest compared with lowest category of intake. Those in the highest category of vitamin C intake had a lower risk of EAC (OR = 0.37; 95% CI = 0.21-0.66; P-trend = 0.001) and RE (OR = 0.46; 95% CI = 0.24-0.90; P-trend = 0.03) compared with those in the lowest category. Vitamin C intake was not associated with BE, and intake of vitamin E, total carotenoids, zinc, copper, or selenium was not associated with EAC, BE, or RE. In conclusion, the overall antioxidant index was associated with a reduced risk of EAC. Higher dietary intake of vitamin C was associated with a reduced risk of EAC and RE. These results suggest that antioxidants may play a role in the pathogenesis of RE and EAC and may be more important in terms of progression rather than initiation of the disease process"
  • Natural substance NT-020 aids aging brains in rats, study finds - Science Daily, 7/20/10 - "Aging has been linked to oxidative stress, and we have previously shown that natural compounds made from blueberries, green tea, and amino acids, such as carnosine, are high in antioxidants and have anti-inflammatory and anti-oxidative activity .... The combination of these nutrients, called NT-020, creates a synergistic effect that promotes the proliferation of stem cells in the aged animals ... NT-020 may have not only a positive effect on the stem cell niche ... NT-020 may have far-reaching effects on organ function beyond the replacement of injured cells, as demonstrated by cognitive improvement in the NT-020 group"
  • Antioxidants do help arteries stay healthy - Science Daily, 7/5/10 - "Long-term supplementation with dietary antioxidants has beneficial effects on sugar and fat metabolism, blood pressure and arterial flexibility in patients with multiple cardiovascular risk factors ... receive either antioxidants or placebo capsules for six months. Tests at the beginning of the trial, after three months and at the six month mark revealed that the patients in the antioxidant group had more elastic arteries (a measure of increased cardiovascular health) and better blood sugar and cholesterol profiles"
  • Well-defined quantity of antioxidants in diet can improve insulin resistance, study finds - Science Daily, 6/21/10 - "For groups C and D, the researchers prescribed a diet enriched in antioxidant, with a calculated intake, 800 to 1,000 milligrams a day, coming from fruits and vegetables, but group D also took metformin ... Despite similar weight loss in all the groups, only the two groups receiving the antioxidant diet (groups C and D) had a significant decrease in insulin resistance ... Group D had the best improvement in insulin resistance on some measures of insulin response to an oral glucose tolerance test ... We think that a total antioxidant level of 800 to 1,000 milligrams a day is safe and probably not close to the maximum tolerable level"
  • Supplement your stem cells - Science Daily, 4/7/10 - "supplement, containing a cocktail of green tea, astralagus, goji berry extracts, 'good' bacteria Lactobacillus fermentum, antioxidant ellagic acid, immune enhancer beta 1,3 glucan and vitamin D3, was able to increase the number of stem cells circulating in the blood ... Hematopoietic stem cells and endothelial progenitor cells increased after taking the nutritional supplement, suggesting that the supplement may be a useful stimulator for both types of stem cells. In this study, the levels of these stem cells peaked at 2-7 days and started to drop at 14 days, suggesting that this supplement could be used for continuous treatment for conditions associated with decreases in these stem cells such as Alzheimer's Disease ... it may be possible that our supplement could be beneficial in conditions associated with reduced progenitor cells such as diabetes"
  • Vitamin combo may delay ageing: Mouse study - Nutra USA, 3/1/10 - "Results showed maintenance of youthful levels of locomotor activity into old age in the supplemented animals, whereas old non-supplemented mice showed a 50 per cent loss in daily movement, said the researchers. This was accompanied by a loss of mitochondria activity, and declines in brain signalling chemicals relevant to locomotion, such as striatal neuropeptide Y. This chemical is associated with a range of functions, including maintaining energy balance, as well as effects in memory and learning ... No such declines were observed in supplemented animals ... The supplement was composed of vitamins B1, B3 (niacin), B6, B12, C, D, E, folic acid, beta-carotene, CoQ10, rutin, bioflavonoids, ginko biloba, ginseng, green tea extract, ginger root extract, garlic, L-Glutathione, magnesium, selenium, potassium, manganese, chromium picolinate, acetyl L-carnitine, melatonin, alpha-lipoic acid, N-acetyl cysteine, acetylsalicylic acid, cod liver oil, and flax seed oil"
  • Dietary Antioxidants Could Help Preserve Muscle Strength in Older Adults - Medscape, 11/23/09 - "In a study in older adults, dietary intake of vitamins C and E was linked with muscle strength, leading the researchers to suggest at a meeting in Atlanta this past weekend that a diet high in antioxidants could play an important role in preserving muscle function in older adults ... Muscle strength is really a marker of aging ... Muscle strength starts declining when people are in their 40s, but it decreases dramatically after age 60 ... At this point, it's not clear whether vitamins C and E specifically help preserve muscle strength, or if intake of these micronutrients is a marker of a healthy diet"

  • Antioxidants needed by exercising populations: Nutritionist - Nutra USA, 5/14/09 - "Commenting on the design of the study, Dr Childs said it was unclear if the subjects encountered the same absolute level of muscle fatigue during exercise in the supplement and control conditions and hence stimulus for antioxidant up-regulation. “Because of this, the reported ‘prevention of the ‘health promoting effects of antioxidants’ may be nothing more than an experimental artefact,” ... In addition, Dr Childs said that comments by the authors that antioxidants may block many of the beneficial effects of exercise were a “gross over extrapolation of the experimental findings on two levels”"
  • Vitamin-exercise study questioned - Nutra USA, 5/12/09 - "The authors noted that biopsies for the ‘early’ time-point were only obtained from five people in the vitamin group, and four in the placebo group. “Yet the authors conclude a “strong induction of PGCl-alpha, PGCl-beta, and PPAR-gamma expression in skeletal muscle following 4 weeks of exercise training in previously untrained, antioxidant naïve individuals” and “markedly reduced exercise-related induction” in those taking antioxidants, based on these limited number of biopsies,” ... “Would it not have made more sense to appropriately increase the intensity and duration of exercise slowly and then see if the subject’s bodies didn’t accommodate handling of ROS without a significant change in induction of these markers?” ... The study reflects a ‘transient’ increase in ROS during ‘limited periods of physical exercise only’, noted Dr Schauss, “whereas the bulk of the literature, including that in non-primate models have not observed these concerns obtained in models of ‘continuous exposure to increased levels of ROS’” ... the authors presented no evidence of adverse effects by any of the individuals from vitamin C and E supplementation"
  • Do Antioxidants Curb an Exercise Benefit? - WebMD, 5/11/09 - "Physical activity induced an increase in insulin sensitivity only in the absence of antioxidants"
  • Antioxidant Found In Berries, Other Foods Prevents UV Skin Damage That Leads To Wrinkles - Science Daily, 4/21/09 - "Using a topical application of the antioxidant ellagic acid, researchers at Hallym University in the Republic of Korea markedly prevented collagen destruction and inflammatory response – major causes of wrinkles -- in both human skin cells and the sensitive skin of hairless mice following continuing exposure to UV-B, the sun's skin-damaging ultraviolet radioactive rays ... Ellagic acid is an antioxidant found in numerous fruits, vegetables and nuts, especially raspberries, strawberries, cranberries and pomegranates ... the results demonstrate that ellagic acid works to prevent wrinkle formation and photo-aging caused by UV destruction of collagen and inflammatory response"
  • Reductions In Cancer And Overall Mortality Persist 10 Years After Vitamin And Mineral Supplementation - Science Daily, 4/2/09 - "Individuals who took a dietary supplement called "factor D", which included selenium, vitamin E, and beta-carotene, continued to have lower gastric cancer and overall mortality 10 years after supplementation ceased compared with individuals who did not take the supplements ... Individuals who took factor D continued to show benefits, with a 5% reduction in overall mortality (from a cumulative mortality of 33.62% of participants not taking factor D to 32.19% of participants taking factor D) and an 11% reduction in gastric cancer mortality (from a cumulative gastric cancer mortality of 4.28% in the no-factor D group to 3.84% in the factor D group)"
  • Cholinesterase Inhibition Combined With Antioxidants May Help Alzheimer's Disease Outcomes - Doctor's Guide, 3/17/09 - "Addition of a defined antioxidants formulation (Formula F) to donepezil treatment of patients with mild Alzheimer's disease (AD) substantially reduces oxidative stress and provides significant benefits over treatment with donepezil alone"

  • Antioxidant To Retard Wrinkles Discovered - Science Daily, 8/30/07 - "Antioxidants operate against free radicals which cause a breakdown of many tissues in the body, including the skin. When found in small quantities in the body, free radicals are not harmful and are even involved in various physical processes. When there is an excess of free radicals, however, as occurs during normal aging or as a result of excessive exposure to ultra-violet radiation from the sun, the result, among other things, is a breakdown of the collagen and elastin fibers in the skin. When this happens, there is a loss of skin elasticity and the formation of wrinkles ... A problem with many of the commercial antioxidants found today in the market that are said to retard the aging process is that they oxidize quickly and therefore their efficiency declines with time"
