Life has no certainty, you never know, when your destiny will turn around and provides you unwanted health trouble. Today if we look into our lifestyle then we can realize it that we are so much busy in our day to day lives that we do not even have time for healthier food, and so the reason we somehow rely on the meals which are not excellent for our health. Perhaps our stressful lifetime don't let us a chance to take in, but still it is always essential that we should give main concerns to our health so that we can do our jobs nicely.

How much vitamin D3 do the elderly need? Viljakainen HT, Palssa A, Kärkkäinen M, Jakobsen J, Lamberg-Allardt C. J Am Coll Nutr. 2006 Oct;25(5):429-35. PMID: 17031013 Conclusions: A clear dose response was noted in S-25-OHD to different doses of vitamin D3. The recommended dietary intake of 15 µg is adequate to maintain the S-25-OHD concentration around 40-55 nmol/L during winter, but if the optimal S-25-OHD is higher than that even higher vitamin D intakes are needed. Interestingly, subjects with lower vitamin D status at baseline responded more efficiently to supplementation than those with more adequate status

Why would vitamin D be prescribed when vitamin D3 is available over-the-counter? Let's review the known differences between vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol): --D3 is the human form; D2 is the non-human form found in plants. --Dose for dose, D3 is more effective at raising blood levels of 25-hydroxy vitamin D than D2. It requires roughly twice to 250% of the dose of D2 to match that of D3 (Trang H et al 1998). --D2 blood levels don't yield long-term sustained levels of 25-hydroxy vitamin D as does D3. When examined as a 28-day area under the curve (AUC--a superior measure of biologic exposure), D3 yields better than a 300% increased potency compared to D2. This means that it requires around 50,000 units D2 to match the effects of 15,000 units D3 (Armas LA et al 2004). --D2 has lower binding affinity for vitamin D-binding protein, compared to D3 --Mitochondrial vitamin D 25-hydroxylase converts D3 to the 25-hydroxylated form five times more rapidly than D2. --As we age, the ability to metabolize D2 is dramatically reduced, while D3 is not subject to this phenomenon

Incidence of reported cold/influenza symptoms according to season. The 104 subjects in the placebo group (light shade) reported cold and flu symptoms year around with the most symptoms in the winter. While on 800 IU per day (intermediate shade) the 104 test subjects were as likely to get sick in the summer as the winter. Only one of the 104 test subjects had cold/influenza symptoms during the final year of the trial, when they took 2,000 IU of vitamin D per day (dark shading).

San Diego, CA (PRWEB) May 25, 2009 -- Coming on the heels of the publishing in the Annals of Epidemiology of a new study led by Dr. Cedric Garland, on the preventive measures of vitamin D, GrassrootsHealth D*action Project is calling on physicians, health clinics and groups throughout the country to recognize the need for determining vitamin D levels and to ensure the public have their blood levels of vitamin D tested. According to research from the newly published study by Cedric F. Garland, Dr. P.H., FACE, Department of Family and Preventive Medicine and Moores Cancer Center of the University of California, San Diego (UCSD), "It is projected that raising the minimum year-around serum 25(OH)D level to 40-60 ng/ml (100-150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three quarters of deaths from these diseases, in the US and Canada."

The American diet circa 2007 is a disaster - but positive change has begun. Those were the twin themes of the "Fourth Annual Nutrition and Health Conference" held in San Diego, Calif., May 14-16, 2007. The conference was sponsored by the University of Arizona's College of Medicine in conjunction with the Program in Integrative Medicine (PIM); PIM was founded and is co-directed by Dr. Weil. \n\nThe three-day event brought together leading nutrition researchers from around the world, bearing plenty of both bad and good news. Some highlights:

"So why is Dr Vieth so frustrated? You might think he'd have cause for celebration. But for him and other vitamin D researchers around the world, the good news comes with a bitter aftertaste. They believe they can prove vitamin D could help millions live longer and be healthier and yet they have not been able to convince their own governments. In the US and Canada, official vitamin D policy is set by the Institute of Medicine. And in the opinion of Vieth, the current recommendations - 200 International Units per day for people under 50, 400 for people aged 51-70, and 600 for those 71 and older - are outrageously low. Bruce Hollis, professor of paediatrics at the Medical University of South Carolina, calls 400 IU a day "a joke". That's because the best research suggests that to achieve the higher vitamin D blood levels associated with disease prevention, most adults in the US would need to take 1,000-2,000 IU a day: five to 10 times more than the current official recommendation for adult In 1999, Reinhold Vieth (pictured right) published a review of vitamin D research in response to the IOM conclusions. In it, he argued that there was no evidence that amounts lower than 20,000 IU a day could be toxic. "Throughout my preparation of this review, I was amazed at the lack of evidence supporting statements about the toxicity of moderate doses of vitamin D," Vieth wrote. Studies have since shown 10,000 IU a day of vitamin D to be safe. While any substance will become toxic in excess, vitamin D researchers today accept that the current vitamin D recommendations could be more than quadrupled with no fear of toxicity.!

Diagnosis and treatment of vitamin D deficiency. Cannell JJ, Hollis BW, Zasloff M, Heaney RP. Expert Opin Pharmacother. 2008 Jan;9(1):107-18. PMID: 18076342 The recent discovery - in a randomised, controlled trial - that daily ingestion of 1100 IU of colecalciferol (vitamin D) over a 4-year period dramatically reduced the incidence of non-skin cancers makes it difficult to overstate the potential medical, social and economic implications of treating vitamin D deficiency. Not only are such deficiencies common, probably the rule, vitamin D deficiency stands implicated in a host of diseases other than cancer. The metabolic product of vitamin D is a potent, pleiotropic, repair and maintenance, secosteroid hormone that targets > 200 human genes in a wide variety of tissues, meaning it has as many mechanisms of action as genes it targets. A common misconception is that government agencies designed present intake recommendations to prevent or treat vitamin D deficiency. They did not. Instead, they are guidelines to prevent particular metabolic bone diseases. Official recommendations were never designed and are not effective in preventing or treating vitamin D deficiency and in no way limit the freedom of the physician - or responsibility - to do so. At this time, assessing serum 25-hydroxy-vitamin D is the only way to make the diagnosis and to assure that treatment is adequate and safe. The authors believe that treatment should be sufficient to maintain levels found in humans living naturally in a sun-rich environment, that is, > 40 ng/ml, year around. Three treatment modalities exist: sunlight, artificial ultraviolet B radiation or supplementation. All treatment modalities have their potential risks and benefits. Benefits of all treatment modalities outweigh potential risks and greatly outweigh the risk of no treatment. As a prolonged 'vitamin D winter', centred on the winter solstice, occurs at many temperate latitudes, ≤ 5000 IU (125 μg) of vitamin D/d

Vitamin D for cancer prevention: global perspective. Garland CF, Gorham ED, Mohr SB, Garland FC. Ann Epidemiol. 2009 Jul;19(7):468-83. Review. PMID: 19523595 RESULTS/CONCLUSIONS: It is projected that raising the minimum year-around serum 25(OH)D level to 40 to 60 ng/mL (100-150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three fourths of deaths from these diseases in the United States and Canada, based on observational studies combined with a randomized trial. Such intakes also are expected to reduce case-fatality rates of patients who have breast, colorectal, or prostate cancer by half. There are no unreasonable risks from intake of 2000 IU per day of vitamin D(3), or from a population serum 25(OH)D level of 40 to 60 ng/mL. The time has arrived for nationally coordinated action to substantially increase intake of vitamin D and calcium.

"With daily news reports warning of a swine flu pandemic, members have besieged our health advisors with questions about what they should do to protect themselves against the H1N1 (swine flu) virus. The good news is that Life Extension® members obtain a considerable amount of immune support via the supplements they already use, especially those taking high-dose vitamin D. An important question, however, is what one should do if they develop symptoms of a viral infection? As the days grow colder, the risks of contracting common flu and cold viruses increase. Each year, flu virus infections kill around 36,000 Americans and cause miseries for millions.1 An outbreak of the swine flu virus is expected this winter. While certain supplements (and drugs) purport to shorten the duration of a viral infection, most of them fail to provide significant relief. Over the past 28 years, Life Extension® personnel have experimented with various nutrients, hormones, and drugs in order to minimize the impact of the common cold and typical flu viruses. In this article, I will reveal what has worked for me personally to ward off common cold/flu viruses and what has been validated in the scientific literature to be effective. I will also elaborate on some aggressive prescription drug strategies to consider in the event that you contract a severe form of swine flu or other type of influenza."
