    Vitamin D and its role in skeletal muscle. Ceglia L. Curr Opin Clin Nutr Metab Care. 2009 Sep 18. [Epub ahead of print] PMID: 19770647 SUMMARY: Further studies are needed to fully characterize the underlying mechanisms of vitamin D action in human muscle tissue, to understand how these actions translate into changes in muscle cell morphology and improvements in physical performance, and to define the 25-hydroxyvitamin D level at which to achieve these beneficial effects in muscle.

Vitamin D Tied To Muscle Power In Adolescent Girls - 0 views

  •  
    ScienceDaily (Feb. 10, 2009) - Vitamin D is significantly associated with muscle power and force in adolescent girls, according to a new study. Although vitamin D is naturally produced in the body through exposure to direct sunlight, vitamin D deficiency has become widely common in the United States. Vitamin D deficiency has been shown to have a significant negative impact on muscle and bone health, and can lead to conditions including osteoporosis and rickets.

    Vitamin D supplementation improves neuromuscular function in older people who fall. Dhesi JK, Jackson SH, Bearne LM, Moniz C, Hurley MV, Swift CG, Allain TJ. Age Ageing. 2004 Nov;33(6):589-95. PMID: 15501836 doi:10.1093/ageing/afh20 9 CONCLUSIONS: vitamin D supplementation, in fallers with vitamin D insufficiency, has a significant beneficial effect on functional performance, reaction time and balance, but not muscle strength. This suggests that vitamin D supplementation improves neuromuscular or neuroprotective function, which may in part explain the mechanism whereby vitamin D reduces falls and fractures.

Vitamin D A Key Player In Overall Health Of Several Body Organs, Says Biochemist - 0 views

  •  
    Vitamin D A Key Player In Overall Health Of Several Body Organs, Says Biochemist In a paper published in the August issue of the American Journal of Clinical Nutrition, Norman identifies vitamin D's potential for contributions to good health in the adaptive and innate immune systems, the secretion and regulation of insulin by the pancreas, the heart and blood pressure regulation, muscle strength and brain activity. In addition, access to adequate amounts of vitamin D is believed to be beneficial towards reducing the risk of cancer. Norman also lists 36 organ tissues in the body whose cells respond biologically to vitamin D. The list includes bone marrow, breast, colon, intestine, kidney, lung, prostate, retina, skin, stomach and the uterus.

Vitamin D for Pain - 0 views

  •  
    According to peer-reviewed clinical research, inadequacies of vitamin D have been linked to chronic musculoskeletal pain of various types, muscle weakness or fatigue, fibromyalgia syndrome, rheumatic disorders, osteoarthritis, hyperesthesia, migraine headaches, and other somatic complaints. It also has been implicated in the mood disturbances of chronic fatigue syndrome and seasonal affective disorder. Current best evidence demonstrates that supplemental vitamin D can help to resolve or alleviate chronic pain and fatigue syndromes in many patients who have been unresponsive to other therapies. Vitamin D therapy is easy for patients to self-administer, is well tolerated, and is very economical. The documents on this page provide detailed background information and practice recommendations.

Vitamin D in preventive medicine: are we ignoring the evidence? - 0 views

    Vitamin D in preventive medicine: are we ignoring the evidence? Zittermann A. Br J Nutr. 2003 May;89(5):552-72. Review. PMID: 12720576 Vitamin D is metabolised by a hepatic 25-hydroxylase into 25-hydroxyvitamin D (25(OH)D) and by a renal 1alpha-hydroxylase into the vitamin D hormone calcitriol. Calcitriol receptors are present in more than thirty different tissues. Apart from the kidney, several tissues also possess the enzyme 1alpha-hydroxylase, which is able to use circulating 25(OH)D as a substrate. Serum levels of 25(OH)D are the best indicator to assess vitamin D deficiency, insufficiency, hypovitaminosis, adequacy, and toxicity. European children and young adults often have circulating 25(OH)D levels in the insufficiency range during wintertime. Elderly subjects have mean 25(OH)D levels in the insufficiency range throughout the year. In institutionalized subjects 25(OH)D levels are often in the deficiency range. There is now general agreement that a low vitamin D status is involved in the pathogenesis of osteoporosis. Moreover, vitamin D insufficiency can lead to a disturbed muscle function. Epidemiological data also indicate a low vitamin D status in tuberculosis, rheumatoid arthritis, multiple sclerosis, inflammatory bowel diseases, hypertension, and specific types of cancer. Some intervention trials have demonstrated that supplementation with vitamin D or its metabolites is able: (i) to reduce blood pressure in hypertensive patients; (ii) to improve blood glucose levels in diabetics; (iii) to improve symptoms of rheumatoid arthritis and multiple sclerosis. The oral dose necessary to achieve adequate serum 25(OH)D levels is probably much higher than the current recommendations of 5-15 microg/d.

    Vitamin D protects bone, preserves muscle strength, and regulates cell growth and energy metabolism. It also offers some protection against cancer and other disease, but are these effects really important for health and life expectancy? The answer seems to be a resounding yes.

    Concentrations of vitamin D3 and 25-hydroxyvitamin D3 in raw and cooked New Zealand beef and lamb. Roger Purchas, Maggie Zoua, Philip Pearcea and Felicity Jackson- Journal of Food Composition and Analysis Volume 20, Issue 2, March 2007, Pages 90-98 For lamb, the highest levels of vitamin D3 were in the shoulder chop both before and after cooking, while levels were lowest in the rack muscle. Similar cut differences were shown for 25OHD3 concentrations. For beef there were no significant differences between the cuts for vitamin D3, but concentrations of 25OHD3 were lower in the striploin before and after cooking, Vitamin D3 levels tended to be higher in beef cuts than in lamb cuts, but the opposite held for 25OHD3. Concentrations of vitamin D3 were similar to those in other reports, but the 25OHD3 levels were at the high end of reported ranges. With 25OHD3 being more potent than vitamin D3, it is concluded that meat can make a useful contribution of this vitamin to the human diet.

    "Last Wednesday night I gave a lecture to my clients on hunter-gatherer diets. The turnout was great and the information was well-received. I had it professionally video-recorded and will probably offer this as a DVD for sale (with the handout included). Watch for it in the future. Part of what I discussed was vitamin D3 supplementation. Since I have been supplementing with 4,000-10,000 Units of D3 per day I have noted enhanced recovery and size response from my training. Apparently, skeletal muscle has both surface receptors and nuclear receptors for D3 that augment calcium flux during contraction (from surface receptors) and have steroid-like effects at the nuclear level WRT protein synthesis. This D3 supplementation is not really "supplementation" but is instead "augmentation" to levels that would be normal if we got normal sun exposure as we did in our evolutionary past. Check out www.vitamindcouncil.org for more information. Also, check out this abstract below for your consideration. Also, check out this article."

    Vitamin D, nervous system and aging. P. Tuohimaa, T. Keisala, A. Minasyan, J. Cachat and A. Kalueff. . Psychoneuroendocrinology, Volume 34, Supplement 1, December 2009, Pages S278-S286 NEUROACTIVE STEROIDS: EFFECTS AND MECHANISMS OF ACTION doi:10.1016/j.psyneuen.2009.07.003 This is a mini-review of vitamin D3, its active metabolites and their functioning in the central nervous system (CNS), especially in relation to nervous system pathologies and aging. The vitamin D3 endocrine system consists of 3 active calcipherol hormones: calcidiol (25OHD3), 1α-calcitriol (1α,25(OH)2D3) and 24-calcitriol (24,25(OH)2D3). The impact of the calcipherol hormone system on aging, health and disease is discussed. Low serum calcidiol concentrations are associated with an increased risk of several chronic diseases including osteoporosis, cancer, diabetes, autoimmune disorders, hypertension, atherosclerosis and muscle weakness all of which can be considered aging-related diseases. The relationship of many of these diseases and aging-related changes in physiology show a U-shaped response curve to serum calcidiol concentrations. Clinical data suggest that vitamin D3 insufficiency is associated with an increased risk of several CNS diseases, including multiple sclerosis, Alzheimer's and Parkinson's disease, seasonal affective disorder and schizophrenia. In line with this, recent animal and human studies suggest that vitamin D insufficiency is associated with abnormal development and functioning of the CNS. Overall, imbalances in the calcipherol system appear to cause abnormal function, including premature aging, of the CNS.

    My doctor advised us to give Vitamin D to both our children, though our son is more than 4 year old. I decided to find out more about it. I surfed the Internet, read the description of the vitamin (here Canadian Pharmacy site https://www.canadapharmacy.com/ helped me a lot). Finally, I decided to give it to my children. But I didn't know, it is good for adults. Thanks for sharing this information, it is very useful for me!
