  • 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" - 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.
  • Vitamin A is for anti-aging, at least when it comes to vision - The Washington Post, 7/14/15 - "There are essentially two forms of the vitamin: retinoids, or preformed vitamin A, found in animal products and carotenoids; and provitamin A, dark-colored plant pigments that are converted to vitamin A in the body ... Food sources: Liver, shrimp, salmon, sardines, halibut, cod, beef, lamb, eggs, whole milk, whole yogurt ... Carotenoids are antioxidants that prevent and repair cellular damage and aging and reduce inflammation in the eyes and elsewhere in the body. The carotenoids lutein and zeaxanthin are found in the retina of the human eye and have been shown to help prevent age-related macular degeneration. Carotenoids also may reduce the risk for cancer ... Food sources: Spinach, kale, Swiss chard, other dark leafy greens, carrots, sweet potatoes, winter squash, apricots and cantaloupe ... Not only does vitamin A help with eyesight by producing the pigments of the retina and preventing macular degeneration, but it also helps create and maintain healthy skin (hence the popularity of topical Retin-A skincare products) ... Avoid excessively bright light from harsh interior lighting or strong sunlight. Most offices are twice as bright as they need to be. Use low-intensity light bulbs and floor lamps instead of fluorescent lighting" - See Puritan's Pride Lutein 20 mg with Zeaxanthin-120 Softgels at Amazon.com.
  • Aerobic exercise protects retinal function and structure from light-induced retinal degeneration - J Neurosci. 2014 Feb 12;34(7):2406-12 - "After 2 weeks of exercise, mice were exposed to either toxic bright light (10,000 lux) for 4 h to induce photoreceptor degeneration or maintenance dim light (25 lux). Bright light caused 75% loss of both retinal function and photoreceptor numbers. However, exercised mice exposed to bright light had 2 times greater retinal function and photoreceptor nuclei than inactive mice exposed to bright light"
  • Lower dairy products and calcium intake is associated with adverse retinal vascular changes in older adults - Nutr Metab Cardiovasc Dis. 2014 Jan 10 - "Higher consumption of dairy products and calcium is likely to play a role in maintaining optimal vascular health ... 2813 Blue Mountains Eye Study participants aged 50+ years had dietary data collected using a semi-quantitative food frequency questionnaire, and serves of dairy consumption were calculated. Fundus photographs were taken and retinal vascular caliber measured using computer-assisted techniques and summarized ... participants in the lowest quintile of total dairy consumption compared to those in the remaining highest 4 quintiles had significantly wider retinal venular caliber, 227.2 versus 224.7 μm, respectively (multivariable-adjusted p = 0.002)"
  • Nutrients Promote Eye Health in Aging, Says Panel - Medscape, 4/17/12 - "They pointed out that many multivitamin supplements do not contain nutrients important for eye health, including lutein, zeaxanthin, and long-chain omega-3 fatty acids. "Taking a supplement specifically designed for eye health that contains these key nutrients, in addition to a general nutritional supplement, may therefore be a better approach to filling dietary shortfalls,""
  • Effects of dietary supplementation with a combination of fish oil, bilberry extract, and lutein on subjective symptoms of asthenopia in humans - Biomed Res. 2011;32(6):387-93 - "supplement containing omega-3 fatty acid-rich fish oil (docosahexaenoic acid 783 mg/day, eicosapentaenoic acid 162 mg/day), bilberry extract (anthocyanidin 59 mg/day), and lutein (17.5 mg/day) in soft gel capsule form, every day for 4 weeks ... Asthenopia [eye strain] symptoms such as "stiff shoulder, low back pain", "frustration", "dry-eye", and "stuffy head" were improved in the Active group. Furthermore, a score of mental fatigue was improved after 4 weeks of supplementation, and no side effects were observed after the 4-week supplementation and a 2-week washout period in the Active group. These results suggest that dietary supplementation with the combination of omega-3 fatty acid-rich fish oil, bilberry extract, and lutein may safely improve subjective symptoms of asthenopia and mental fatigue in humans" - See Jarrow Max DHA at Amazon.com, bilberry at Amazon.com and Jarrow Formulas, CarotenALL at Amazon.com.
  • Green Tea Good for the Eyes? - WebMD, 2/18/10 - "the compounds responsible for many of the health benefits of green tea are capable of penetrating the tissues of the eyes and have antioxidant activity there ... catechins are among a number of antioxidants, including vitamin C, vitamin E, lutein, and zeaxanthin, thought to help protect the delicate tissues of the eye from glaucoma and other eye diseases. But until now it wasn't known if the catechins in green tea were capable of being absorbed into the tissues of the eye ... The results showed that different parts of the eye absorbed varying amounts of catechins. The area with the highest concentration of catechins was the retina, which is the light-sensing tissue that lines the back of the eye" - [Science Daily] - See green tea extract at Amazon.com.
  • Fruits, Leafy Greens Are Good for the Eyes - WebMD, 12/22/09 - "These foods contain the carotenoids such as lutein and zeaxanthin, which play an important role in vision and have a positive impact on the retina ... Lutein and zeaxanthin may help reduce disability and discomfort from glare, enhance contrast, and reduce photostress recovery times ... about 600 carotenoids can be identified in nature ... Lutein and zeaxanthin are found in kale and spinach, among other vegetables ... Of about 20 carotenoids found in human blood, only lutein and zeaxanthin are found in the visual system, the researchers write, suggesting these pigments play a "special role" in human vision" - Great, I'll definitely stock up on kale. That'd be as much fun as eating worms from my lawn.  See Jarrow Formulas, CarotenALL, Mixed Carotenoid Complex at Amazon.com.

  • Pycnogenol((R)) Improves Microcirculation, Retinal Edema and Visual Acuity in Early Diabetic Retinopathy - J Ocul Pharmacol Ther. 2009 Nov 16 - "Results: The major positive observation of this study is the visual improvement, which was subjectively perceived by 18 out of 24 patients in the Pycnogenol group. Testing of visual acuity using the Snellen chart showed a significant improvement from baseline 14/20 to 17/20 already, after 2 months treatment, whereas no change was found in the control group. Conclusions: Pycnogenol taken at this early stage of retinopathy may enhance retinal blood circulation accompanied by regression of edema, which favorably improves vision of patients" - See Pycnogenol at Amazon.com or grape seed extract at Amazon.com (some say that the grapeseed extract is the same thing without the patent markup).
  • Low vitamin B6 and folic acid levels are associated with retinal vein occlusion independently of homocysteine levels - Atherosclerosis. 2007 Oct 16 - "Retinal vein occlusion (RVO) is one of the most common retinal vascular disorders ... Blood levels of vitamin B6, folate and Hcy, but not of vitamin B12, were found to be significantly different in patients as compared to healthy subjects. At the univariate analysis, the lowest tertile of vitamin B6 [odds ratio (OR) 4.03; 95% confidence interval (CI) 2.58-6.31; P<0.0001)] and folate (OR 6.13; 95% CI 3.85-9.76, P<0.0001), and the highest tertile of Hcy (OR 8.08; 95% CI 5.05-12.92, P<0.0001) were found to be significantly associated with RVO. Moreover, at multivariate analysis, after adjustment for traditional cardiovascular risk factors, Hcy, and circulating levels of vitamins, respectively, the lowest tertile of vitamin B6 (OR 3.29; 95% CI 1.89-5.70, P<0.0001) and folate (OR 5.41; 95% CI 3.08-9.51, P<0.0001) and the highest tertile of Hcy (OR 2.58; 95% CI 1.12-5.94, P<0.0001) maintained their significant association with RVO"
  • Beta-Carotene Pills May Not Help Aging Eyes - WebMD, 3/14/07 -  "The difference between the two groups was so small that it could have been due to chance" - Note:  Beta-carotene is just one of over 600 carotenoids and many believe that taking mega-doses of just one carotenoid can cause a deficiency of the others.  I get my carotenoids from food, dunaliella salina algae (Body Wise), Jarrow Lyco-Sorb (contains Lyco-O-Mato), Biolut™ Marigold extract and Nature's Way, Multi-Carotene Anti-oxidant.
