Bifidobacterium longum
supplementation improves age-related delays in fracture repair - Aging Cell
2023 Jan 27 - "Age-related delays in bone repair remains
an important clinical issue that can prolong pain and suffering. It is now well
established that inflammation increases with aging and that this exacerbated
inflammatory response can influence skeletal regeneration. Recently, simple
dietary supplementation with beneficial probiotic bacteria has been shown to
influence fracture repair in young mice ... We found that B. longum
supplementation accelerated bony callus formation which improved mechanical
properties of the fractured limb. We attribute these pro-regenerative effects of
B. longum to preservation of intestinal barrier, dampened systemic inflammation,
and maintenance of the microbiota community structure. Moreover, B. longum
attenuated many of the fracture-induced systemic pathologies. Our study provides
evidence that targeting the gut microbiota using simple dietary approaches can
improve fracture healing outcomes and minimize systemic pathologies in the
context of aging." - See probiotic supplements at Amazon.com.

Can Metformin Reduce Need
for Total Joint Replacement in Diabetes? - Medscape, 12/20/22 -
"Compared with nonusers, metformin users had had a 30%
lower risk of total knee or hip replacement (adjusted hazard ratio [HR], 0.70).
The incidence of total knee replacement among metformin nonusers and users was
4.15 per 10,000 person-months and 2.96 per 10,000 person-months, respectively.
The incidence of total hip replacement was 0.83 per 10,000 person-months in
nonusers and 0.44 per 10,000 person-months in users ... By joint type, the
adjusted HR was 0.71 for total knee replacement and 0.61 for total hip
replacement among metformin users ... The effect was observed at daily doses of
less than 1 g, as well as daily doses of 1 g or more. "This suggests that
metformin at a lower dosage could have effects on osteoarthritis,"" -

Melatonin promotes the
restoration of bone defects via enhancement of miR-335-5p combined with
inhibition of TNFα/NF-κB signaling - FASEB J 2023 Jan;37(1) -
"Accelerating
the repair of a bone defect is crucial clinically due to the increased
prevalence of trauma, tumor, and infections in bone. Studies have found that
excess acute and chronic inflammation attenuate osteogenic differentiation of
BMSCs (bone marrow mesenchymal stem cells). Moreover, TNF-α and NF-κB could
inhibit osteoblasts differentiation of BMSCs and promote osteoclastogenesis via
multiple mechanisms, such as increasing osteoclast precursor cells and acting
synergistically with cell cytokines. However, melatonin could inhibit the
expression of TNFα/NF-κB and promote bone formation by activating the Wnt/β-catenin
signaling pathway ... In conclusion, melatonin facilitates osteogenesis in bone
defect healing by enhancing miR-335-5p expression and inhibiting the TNFα/NF-κB
pathway." - See melatonin at Amazon.com.

Nicotinamide mononucleotide
alleviates osteoblast senescence induction and promotes bone healing in
osteoporotic mice - J Gerontol A Biol Sci Med Sci 2022 Aug 29 -
"Combating the accumulated senescent cells and the
healing of osteoporotic bone fracture in the elderly remains a significant
challenge. Nicotinamide mononucleotide (NMN), a precursor of NAD +, is an
excellent candidate for mitigating aging-related disorders. However, it is
unknown if NMN can alleviate senescent cell induction and enhance osteoporotic
bone fracture healing. Here we show that NMN treatment partially reverses the
effects of tumor necrosis factor-alpha (TNF-α) on human primary osteoblasts
(HOBs): senescent cell induction, diminished osteogenic differentiation ability
and intracellular NAD + and NADH levels. Mechanistically, NMN restores the
mitochondrial dysfunction in HOBs induced by TNF-α evidenced by increased
mitochondrial membrane potential and reduced reactive oxidative species and
mitochondrial mass. NMN also increases mitophagy activity by down-regulating P62
expression and up-regulating light chain 3B-II (LC3B-II) protein expression. In
addition, the cell senescence protective effects of NMN on HOBs are mitigated by
a mitophagy inhibitor (Bafilomycin A1). In vivo, NMN supplementation attenuates
senescent cell induction in growth plates, partially prevents osteoporosis in an
ovariectomized mouse model and accelerates bone healing in osteoporotic mice. We
conclude that NMN can be a novel and promising therapeutic candidate to enhance
bone fracture healing capacity in the elderly." - See

New Horizons in the
Treatment of Age-Associated Obesity, Sarcopenia and Osteoporosis - Drugs
Aging 2022 Jul 4 - "The rapid increase in both the
lifespan and proportion of older adults in developed countries is accompanied by
the dramatic growth of age-associated chronic diseases, including obesity,
sarcopenia, and osteoporosis. Hence, prevention and treatment of age-associated
chronic diseases has become increasingly urgent. The key to achieving this goal
is a better understanding of the mechanisms underlying their pathophysiology,
some aspects of which, despite extensive investigation, are still not fully
understood. Aging, obesity, sarcopenia, and osteoporosis are characterized by
the creation of a systemic, chronic, low-grade inflammation (SCLGI). The common
mechanisms that govern the development of these chronic conditions include a
failed resolution of inflammation. Physiologically, the process of inflammation
resolution is provided mainly by specialized pro-resolving mediators (SPMs)
acting via cognate G protein-coupled receptors (GPCRs). Noteworthy, SPM levels
and the expression of their receptors are significantly reduced in aging and the
associated chronic disorders. In preclinical studies, supplementation of SPMs or
their stable, small-molecule SPM mimetics and receptor agonists reveals clear
beneficial effects in inflammation-related obesity and sarcopenic and
osteoporotic conditions, suggesting a translational potential. Age-associated
chronic disorders are also characterized by gut dysbiosis and the accumulation
of senescent cells in the adipose tissue, skeletal muscle, and bones. Based on
these findings, we propose SCLGI resolution as a novel strategy for the
prevention/treatment of age-associated obesity, sarcopenia, and osteoporosis.
Our approach entails the enhancement of inflammation resolution by SPM mimetics
and receptor agonists in concert with probiotics/prebiotics and compounds that
eliminate senescent cells and their pro-inflammatory activity" - See

SHBG, bone mineral density
and physical function among injection drug users with and without HIV and HCV
- J Clin Endocrinol Metab 2022 Mar 16 - "Sex
hormone-binding globulin (SHBG) is a glycoprotein that regulates the
bioavailability of sex hormones and is higher in people with HIV (PWH) and
hepatitis C (HCV). SHBG is associated with aging-related diseases, including
osteoporosis and frailty in the general population. However, the relationship
between SHBG concentration and bone mineral density (BMD) and physical function
among PWH and HCV is unclear ... Higher SHBG concentrations are associated with
the presence of HIV and HCV viremia. Among women, but not men, higher SHBG
concentrations were associated with lower grip strength, higher odds of frailty,
and lower lumbar spine BMD" - Note: The thing is, SBHG binds to
testosterone, DHT and estrogen. I believe the binding to estrogen is what
contributes to bone loss. I haven't found an endocrinologist yet that will treat
it. I have one more appointment with one more doctor at UCSD and if that doesn't
work, I'm taking it to small claims court to see if they can force them to treat
it. It's treatable. See the formula on my SHBG page
but they refuse to even work with me on it. It's like pulling teeth just to get
them to check it. They've got a bad case of thinking that they're God.
When you tell an endocrinologist that you have high SHBG, it's like you said
leprosy and they treat you like a disease. I look at
General Petraeus and I'm betting that's what happened to him.

Diosmin, a citrus
fruit-derived phlebotonic bioflavonoid protects rats from chronic kidney
disease-induced loss of bone mass and strength without deteriorating the renal
function - Food Funct 2022 Feb 21 - "Kidney Disease
Improving Global Outcomes (KDIGO) 2017 Clinical Practice Guideline has
recommended treatment decisions for patients with chronic kidney disease (CKD)
with osteoporosis and/or high risk of fracture. Bisphosphonates, the first-line
anti-osteoporosis drugs have the concern of worsening kidney functions.
Moreover, despite impaired bone formation in CKD patients, teriparatide, the
formation-stimulating drug is not recommended. Thus, there is an urgent need for
safe and effective treatment of osteoporosis in CKD patients ... Fibroblast
growth factor-23 and parathyroid hormone were increased in CKD and diosmin
suppressed both. CKD reduced bone mass and deteriorated the microarchitecture of
trabecular bones, and diosmin maintained both to control levels. Bone formation
and strength were impaired in the CKD and diosmin maintained these levels to
control levels. Nanoindentation of bone showed that diosmin significantly
increased tissue hardness over the control. Diosmetin, the metabolic surrogate
of diosmin had comparable pharmacokinetic profiles between the control and CKD
groups. Furthermore, diosmetin (50 mg kg-1) protected against CKD-induced bone
loss. These data suggest that diosmin and its metabolic surrogate, diosmetin
protect against CKD-induced osteopenia. Since diosmin has no renal adverse
effect and protected bone mass and strength in CKD rats, we propose assessing
its anti-osteoporosis effect in CKD patients" - See

osteoporosis - Wikipedia - "Senile osteoporosis
has been recently recognized as a geriatric syndrome with a particular

primary, in which bone loss is a result of aging and secondary, in which
bone loss occurs from various clinical and lifestyle factors.[1] Primary, or
involuntary osteoporosis, can further be classified into Type I or Type
II.[1] Type I refers to postmenopausal osteoporosis and is caused by the
deficiency of estrogen.[1] While senile osteoporosis is categorized as an
involuntary, Type II, and primary osteoporosis, which affects both men and
women over the age of 70 years. It is accompanied by vitamin D deficiency,
body's failure to absorb calcium, and increased parathyroid hormone."

Effects of strawberries on
bone biomarkers in pre- and stage 1-hypertensive postmenopausal women: a
secondary analysis - Food Funct 2021 Dec 13 -
"Postmenopausal women experience an increase in bone remodeling with the rate of
bone resorption superseding the rate of bone formation. This results in a net
bone loss with a subsequent increased risk for osteoporosis and fractures. High
blood pressure (BP) has been associated with loss of bone mineral density and
increased propensity to fractures. Strawberries are rich in polyphenols, which
have been shown to have anti-hypertensive and bone-protective properties ...
Participants (age: 59 ± 6 years; body mass index: 31.5 ± 4.1 kg m-2; systolic
BP: 140 ± 13 mmHg) were randomly assigned to consume (1) 50 g of freeze-dried
strawberry powder (FDSP), (2) 25 g FDSP + 25 g of placebo powder, or (3) 50 g
placebo powder for eight weeks. Results indicate a significant time-by-treatment
interaction (P = 0.04) for serum insulin-like growth factor (IGF)-1, a hormone
that plays a major role in bone formation. Serum concentrations of bone-specific
alkaline phosphatase, a marker of bone formation, and tartrate-resistant acid
phosphatase-5b, a specific marker of bone resorption, were not affected by FDSP
compared to placebo. Although not statistically significant, after eight weeks,
osteocalcin increased in the 50 g FDSP group with a large effect size (d = 0.6)
when compared to the placebo-control group. Adiponectin increased by 5% and 6%
in the 25 g and 50 g FDSP groups, respectively, while it declined in the
placebo-control group by 25% (P = 0.03 for time-by-treatment interaction). Our
findings suggest that consumption of 25 g FDSP increases IGF-1 in postmenopausal
women with pre- and stage 1-hypertension" - See

Anti-osteoporotic potential of Lactobacillus plantarum AR237 and AR495 in
ovariectomized mice J Func Foods, 12/21 -
"Osteoporosis is a common skeletal disease in which bone resorption exceeds bone
formation. Intestinal health has been linked to reduced osteoporosis. The aim of
this study was to compare the anti-osteoporotic and intestinal health effects of
two strains of Lactobacillus plantarum (AR237 and AR495) in ovariectomized (ovx)
C57BL/6 mice. The results showed that AR495 significantly inhibited ovx-induced
bone loss, reduced intestinal permeability, increased the expression of tight
junction proteins, claudin-family proteins, zonula occludens-1 (ZO-1), and
junctional adhesion molecule 3 (JAM-3) in ovx mice. Furthermore, AR495 inhibited
bone resorption by modulating the receptor activator for nuclear factor kappa B
(RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) system, and ameliorated ovx-induced
intestinal inflammatory responses. AR495 improved intestinal microbial
stability, and increased the abundance of short-chain fatty acids
(SCFA)-producing bacteria and fecal SCFA content of ovx mice. Overall, the
findings of this study showed that AR495 was more effective than AR237 at
treating osteoporosis" - [Nutra

Peonidin-3-O-glucoside and
cyanidin increase osteoblast differentiation and reduce RANKL-induced bone
resorption in transgenic medaka - Phytother Res 2021 Oct 26 -
"Experimental and clinical studies suggest a positive
impact of anthocyanins on bone health; however, the mechanisms of anthocyanins
altering the differentiation and function of osteoblasts and osteoclasts are not
fully understood. This work demonstrates that dietary anthocyanins and
resveratrol increased proliferation of cultured human hFOB 1.19 osteoblasts. In
addition, treatment of serum starvation of hFOB osteoblasts with anthocyanins
and resveratrol at 1.0 μg/ml reduced apoptosis, the Bax/Bcl-2 ratio, p53, and
HDAC1 expression, but increased SIRT1/3 and PGC1α mRNA expression, suggesting
mitochondrial and epigenetic regulation. In Sp7/osterix:mCherry transgenic
medaka, peonidin-3-O-glucoside and resveratrol increased osteoblast
differentiation and increased the expression of Sp7/osterix. Cyanidin,
peonidin-3-O-glucoside, and resveratrol also reduced RANKL-induced ectopic
osteoclast formation and bone resorption in col10α1:nlGFP/rankl:HSE:CFP medaka
in doses of 1-4 μg/ml. The results indicate that both cyanidin and
peonidin-3-O-glucoside have anabolic effects on bone, increasing osteoblast
proliferation and differentiation, mitochondrial biogenesis, and by altering the
osteoblast epigenome. Cyanidin and peonidin-3-O-glucoside also reduced
RANKL-induced bone resorption in a transgenic medaka model of bone resorption.
Thus, peonidin-3-O-glucoside and cyanidin appear to both increase bone formation
and reduce bone loss, suggesting that they be further investigated as potential
treatments for osteoporosis and osteomalacia" - See

Dietary calcium intake and
change in bone mineral density in older adults: a systematic review of
longitudinal cohort studies - Eur J Clin Nutr 2021 Jun 15 -
"Most studies found no association between calcium
intake and change in BMD in women (71%) or men (71%). Among women, five studies
reported high rates (>30% of participants) of hormone treatment or osteoporosis
therapy (HT/OT) use; 80% of these studies reported a positive association
between calcium intake and change in BMD, compared with 10% of studies in which
HT/OT use was low. No study in women in which the mean age was >60 years
reported a positive association between calcium intake and change in BMD. We
conclude that calcium intake across the ranges consumed in these studies (mean
intake in all but one study >500 mg/day) is not an important determinant of bone
loss, particularly among women >60 years. The positive findings in studies with
high rates of HT/OT use are likely to arise from confounding as a result of
co-administration of calcium supplements with these medications"

(-)-Epigallocatechin-3-gallate inhibits RANKL-induced osteoclastogenesis via
downregulation of NFATc1 and suppression of HO-1-HMGB1-RAGE pathway - Biomed
Res 2020;41(6):269-277 - "Osteoporosis disturbs the
balance of bone metabolism, and excessive bone resorption causes a decrease in
bone density, thus increasing the risk of fracture.
(-)-Epigallocatechin-3-gallate (EGCG) is the most abundant catechin contained in
green tea. EGCG has a variety of pharmacological activities ... EGCG upregulated
heme oxygenase-1 (HO-1) and suppressed the extracellular release of
high-mobility group box 1 (HMGB1). In addition, EGCG decreased the expression of
the receptor for advanced glycation end products (RAGE), which is the receptor
of HMGB1, in osteoclastogenesis. In summary, our study showed that EGCG could
inhibit osteoclast differentiation through the downregulation of NFATc1 and the
suppression of the HO-1-HMGB1-RAGE pathway. EGCG might have the potential to be
a lead compound that suppresses bone resorption in the treatment of
osteoporosis" - See

Dietary calcium intake
and rate of bone loss in men - Br J Nutr. 2017 Jun 13:1-7 -
"Baseline BMD was not related to dietary Ca intake at
any site, before or after adjustment for covariables. Similarly, bone loss over
2 years was not related to Ca intake at any site, before or after adjustment.
Dietary Ca intake was inversely correlated with PTH at baseline (r -0·19,
P=0·02), but was not associated with the markers of bone turnover. BMD and rates
of bone loss were unrelated to Ca intake in these men. This suggests that
strategies to increase Ca intake are unlikely to impact on the prevalence of and

Coenzyme Q
Protects Against Age-Related Alveolar Bone Loss Associated to n-6
Polyunsaturated Fatty Acid Rich-Diets by Modulating Mitochondrial Mechanisms
- J Gerontol A Biol Sci Med Sci. 2015 Jul 28 - "An

previously associated to n-6 polyunsaturated fatty acid diet was attenuated by
coenzyme Q10. Gene expression analysis suggests that involved mechanisms might
be related to a restored capacity of mitochondria to adapt to aging in gingival

Intake and
serum concentrations of α-tocopherol in relation to fractures in elderly women

"Two cohort studies, the Swedish Mammography Cohort
(SMC; n = 61,433 women) and the Uppsala Longitudinal Study of Adult Men (ULSAM;
n = 1138 men), were used ... A higher hip fracture rate was observed with lower
intakes of α-tocopherol. Compared with the highest quintile of intake, the
lowest quintile had a multivariable-adjusted HR of 1.86 (95% CI: 1.67, 2.06).
The HR of any fracture was 1.20 (95% CI: 1.14, 1.28). α-Tocopherol-containing
supplement use was associated with a reduced rate of hip fracture (HR: 0.78; 95%
CI: 0.65, 0.93) and any fracture (HR: 0.86; 95% CI: 0.78, 0.94). Compared with
the highest quintile of α-tocopherol intake in ULSAM (follow-up: 12 y), lower

showed that as the ratio of omega-6 fatty acids to omega-3s increased, so did
the risk for hip fracture ... Inflammation is associated with an increased risk
of bone loss and fractures, and omega-3 fatty acids are believed to reduce
inflammation ... omega-3 fatty acids have anti-inflammatory properties and
omega-6 fatty acids seem to have both anti- and pro-inflammatory effects ...
women who had the highest ratio of omega-6 to omega-3 fatty acids had nearly
twice the risk of hip fractures compared to women with the lowest ratios. The
current typical American diet contains between 15 and 17 times more omega-6 than
omega-3, a ratio that previous research has suggested should be lowered to
4-to-1, or even 2-to-1, by increasing omega-3s, to improve overall health. The

Low-dose
vitamin K2 (MK-4) supplementation for 12 months improves bone metabolism and
prevents forearm bone loss in postmenopausal Japanese women - J Bone Miner
Metab. 2013 May 24 - "The participants (aged 50-65
years) were randomly assigned to one of two groups according to the MK-4 dose
received: the placebo-control group (n = 24) and the 1.5-mg MK-4 group (n = 24).
The baseline concentrations of undercarboxylated osteocalcin (ucOC) were high in
both groups (>5.1 ng/ml). After 6 and 12 months, the serum ucOC concentrations
were significantly lower in the MK-4 group than in the control group. In the
control group, there was no significant change in serum pentosidine

used a pooled cohort of 4749 men and women ages 65 years and older from the
third National Health and Nutrition Examination Survey (NHANES III, 1988-94) and
NHANES 2000-2004 ... Serum 25OHD was a significant linear predictor of major
osteoporotic fracture and significant quadratic predictor of hip fracture in the
total sample and among those with less than 10 years of follow-up, but it was
not related to risk of either fracture type among those with > 10 years of
follow-up. Major osteoporotic fracture risk was increased by 26-27% for each SD
decrease in serum 25OHD among those with less than 10 years of follow-up. Serum
25OHD was significantly related to risk of major osteoporotic fractures as a

High
physical fitness in young adulthood reduces the risk of fractures later in life
in men: A nationwide cohort study - J Bone Miner Res. 2012 Nov 26 -
"Aerobic capacity and isometric muscle strength were
measured in 435445 Swedish men that conscripted for military service from
1969-1978 ... When comparing men in the lowest and highest decile of physical
fitness, the risk of a fracture was 1.8 times higher (95% CI = 1.6-2.1) and that
of hip fracture was 2.7 times higher (95% CI = 1.6-4.7). The risk of fracture
was also 1.4-1.5 times higher when comparing the extreme deciles of muscle
strength (p < 0.001 for all). In a subcohort of 1009 twin pairs, up to 22% of
the variation in physical fitness and 27-39% of the variation in muscle strength
was attributable to environmental factors unique to one twin, e.g. physical
activity. In conclusion, low aerobic capacity and muscle strength in young
adulthood are associated with an increased risk of low-energy fractures later in

the Women's Health Initiative (WHI) using 201 incident hip fracture cases from
the Bone Mineral Density (BMD) cohort, along with 199 additional incident hip
fracture cases randomly selected from the WHI Observational Study ... In

a-linolenic acid [Hazard ratio (HR) Tertile 3 (T3): 0.44; 95% CI: 0.23-0.85; p
for linear trend 0.0154)], eicosapentaenoic acid (HR T3: 0.46; 95% CI:

with the highest RBC n-6/n-3 ratio (HR T3: 1.96; 95% CI: 1.03-3.70; p for linear
trend 0.0399). RBC PUFAs were not associated with BMD. RBC PUFAs were indicative
of dietary intake of marine n-3 PUFAs (Spearman's rho=0.45, p<0.0001), total n-6
PUFAs (rho=0.17, p<0.0001) and linoleic acid (rho= 0.09, p<0.05). These results
suggest that higher RBC a-linolenic acid, as well as eicosapentaenoic acid and

"The dietary acid load created by the typical Western
diet may adversely impact the skeleton by disrupting calcium metabolism ... 52
men and women (mean age 65.2 + 6.2 years) were randomly assigned to potassium
citrate 60 mmol, 90 mmol or placebo daily with measurements of bone turnover
markers, net acid excretion, and calcium metabolism including intestinal
fractional calcium absorption and calcium balance obtained at baseline and six
months. At six months, net acid excretion was significantly lower in both
treatment groups compared to placebo and negative, meaning subjects' dietary
acid was completely neutralized (-11.3 mmol/day, 60 mmol/day; -29.5 mmol/day,
90 mmol/day, P < 0.001 compared to placebo). At 6-months, 24-hour urine calcium

Effects of
vitamin E on bone turnover markers among US postmenopausal women - J Bone
Miner Res. 2012 Feb 3 - "Increased oxidative stress and
inflammation resulting from aging and declining estrogen levels can lead to
increased bone loss in postmenopausal women. Alpha- and gamma-tocopherol, the
two predominant isomers of vitamin E, have antioxidant and anti-inflammatory
properties, but their effects on bone metabolism have not been well studied in
humans. We examined the associations between dietary and total (diet and
supplements) alpha-tocopherol intake, serum alpha- and gamma-tocopherol levels
and their ratio, and bone turnover markers (BTMs) among postmenopausal women
aged ≥45 years ... serum bone-specific alkaline phosphatase (BAP), a biomarker
of bone formation, and urinary N-telopeptides/creatinine (uNTx/Cr), a biomarker
of bone resorption ... Participants had a mean age of 65.5 +/- 0.6 years and
over 45% used vitamin E (alpha-tocopherol) supplements in the past month.
Vitamin E supplement users had significantly lower serum gamma-tocopherol,
higher serum alpha-tocopherol levels and higher ratio of serum alpha- to
gamma-tocopherol than nonusers. High serum gamma-tocopherol levels and low ratio
of serum alpha- to gamma-tocopherol were associated with increased BAP levels
(P < 0.01 for both). There were no associations between any of the vitamin E
variables and uNTx/Cr. In conclusion, we hypothesize that gamma-tocopherol may
uncouple bone turnover, resulting in more bone formation than resorption.
Vitamin E supplements in the form of alpha-tocopherol suppress serum
gamma-tocopherol levels and may have negative effects on bone formation. Further
research is needed to investigate the potential anabolic effect of
gamma-tocopherol from food sources on bone" - See

Acid diet
(high-meat protein) effects on calcium metabolism and bone health - Curr
Opin Clin Nutr Metab Care. 2010 Aug 16 - "Increased
potential renal acid load resulting from a high protein (intake above the
current Recommended Dietary Allowance of 0.8 g protein/kg body weight) intake
has been closely associated with increased urinary calcium excretion. However,
recent findings do not support the assumption that bone is lost to provide the
extra calcium found in urine. Neither whole body calcium balance is, nor are
bone status indicators, negatively affected by the increased acid load. Contrary
to the supposed detrimental effect of protein, the majority of epidemiological
studies have shown that long-term high-protein intake increases bone mineral
density and reduces bone fracture incidence. The beneficial effects of protein
such as increasing intestinal calcium absorption and circulating IGF-I whereas
lowering serum parathyroid hormone sufficiently offset any negative effects of
the acid load of protein on bone health"

processing enzyme of the lysyloxidase-precursor and of procollagen. An increase
in the collagen cross-link-ratio Pyr/deDHLNL indicates, that T3 modulated
cross-link maturation in the MC3T3-E1 culture system. These results demonstrate
that T3 directly regulates collagen synthesis and collagen cross-linking by
up-regulating gene expression of the specific cross-link related enzymes, and

Low
calcium intake linked with increased risk of osteoporosis and hypertension in
postmenopausal women - Science Daily, 6/18/10 - "a
significantly increased proportion of women (35.4%) who consumed a lower amount
of calcium through intake from dairy sources, had a concurrent diagnosis of both
hypertension and osteoporosis, compared with women who consumed a higher amount
of calcium (19.3% p<0.001) ... Further statistical analyses revealed that a
lower calcium intake was associated with an increased risk of developing
hypertension or osteoporosis over time when compared with controls (Odds Ratio
(OR) hypertension: 1.43; 95%CI: 1.12-1.82, osteoporosis: OR 1.46; CI:
1.15-1.85). Women who consumed a lower amount of calcium were shown to be most

cell cultures and those designed to mimic weightlessness. The inhibited factor
is known as "nuclear factor kappa B" or NFκB. NFκB is involved in immune system
behavior and the inflammation process. The activation of NFκB in different
tissues can lead to bone and muscle loss" - See Nutra USA article below.

Vitamin D:
What is an adequate vitamin D level and how much supplementation is necessary?
- Best Pract Res Clin Rheumatol. 2009 Dec;23(6):789-95 -
"Vitamin D modulates fracture risk in two ways: by decreasing falls and
increasing bone density. Two most recent meta-analyses of double-blind
randomised controlled trials came to the conclusion that vitamin D reduces the
risk of falls by 19%, the risk of hip fracture by 18% and the risk of any
non-vertebral fracture by 20%; however, this benefit was dose dependent. Fall
prevention was only observed in a trial of at least 700IU vitamin D per day, and
fracture prevention required a received dose (treatment dose*adherence) of more
than 400IU vitamin D per day. Anti-fall efficacy started with achieved
25-hydroxyvitamin D levels of at least 60nmoll(-1) (24 ngml(-1)) and
anti-fracture efficacy started with achieved 25-hydroxyvitamin D levels of at
least 75nmoll(-1) (30ng ml(-1)) and both endpoints improved further with higher
achieved 25-hydroxyvitamin D levels. Founded on these evidence-based data
derived from the general older population, vitamin D supplementation should be
at least 700-1000IU per day and taken with good adherence to cover the needs for
both fall and fracture prevention. Ideally, the target range for
25-hydroxyvitamin D should be at least 75nmoll(-1), which may need more than
700-1000IU vitamin D in individuals with severe vitamin D deficiency or those
overweight" - See

New
Evidence That Green Tea May Help Improve Bone Health - Science Daily,

bone-forming cells (osteoblasts) to three major green tea components —
epigallocatechin (EGC), gallocatechin (GC), and gallocatechin gallate (GCG) —
for several days. They found that one in particular, EGC, boosted the activity
of a key enzyme that promotes bone growth by up to 79 percent. EGC also
significantly boosted levels of bone mineralization in the cells, which
strengthens bones. The scientists also showed that high concentrations of ECG
blocked the activity of a type of cell (osteoclast) that breaks down or weakens
bones. The green tea components did not cause any toxic effects to the bone
cells, they note" - See

causes osteopenia, osteoporosis and osteomalacia, increasing the risk of
fracture. Unlike osteoporosis, which is a painless disease, osteomalacia causes
aching bone pain that is often misdiagnosed as fibromyalgia or chronic pain
syndrome or is simply dismissed as depression. Vitamin D deficiency causes

Vitamin D and Calcium Supplementation Effective for Prevention and Treatment
of Osteoporosis - Doctor's Guide, 7/18/03 -
"Adequate
vitamin D and calcium
intake is essential to the prevention and treatment of osteoporosis. The
Institute of Medicine (IOM) recommends 200 IU/day of vitamin D for women
aged 50 or younger years, 400 IU/day for those aged 51-70 years, and 600
IU/day for those older than 70 years ... In women over the age of 65, there
is increased risk of osteoporotic fracture of the hip and non-vertebral
sites. Daily vitamin D intake between 800 and 900 IU and 1200-1300 mg of
calcium for this population results in increased bone density, decreased
bone turnover, and decreased non-vertebral fractures ... Studies have linked
vitamin D supplementation to a decrease in body sway, suggesting that
vitamin D supplementation may protect against fracture by preventing falls"

Interaction of Dietary Calcium and Protein in Bone Health in Humans - J.
Nutr. 133:852S-854S, 3/03 - "Protein
has both positive and negative effects on calcium
balance, and the net effect of dietary protein on bone mass and fracture
risk may be dependent on the dietary calcium intake. In addition to
providing substrate for bone matrix, dietary protein stimulates the
production of insulin-like growth factor-1 (IGF-1), a factor that promotes
osteoblast-mediated bone formation. Protein also increases urinary calcium
losses, by several proposed mechanisms. Increasing calcium intake may offset
the negative impact of dietary protein on urinary calcium losses, allowing
the favorable effect of protein on the IGF-1 axis to dominate"

It is thought that this loss may be accelerated during menopause, when
hormone levels drop ... The strongest association of the facial wrinkles
with the bone was between the eyebrows ... When we looked at the effects of
sun exposure on skin, we did not see that women who had more sun exposure
