What is NuVision Excel Vitamin D3?
D3-5000 is a natural, soy-free, bio-identical natural vitamin D supplement. Vitamin D, considered not only a hormone, but also a vitamin, is manufactured in the body in response to skin's exposure to sunlight. Vitamin D is essential to the body’s absorption of calcium and strong bones. Natural vitamin D3 (cholecalciferol) is four times more potent than synthetic vitamin D2.* In Latin, calciferol means “calcium carrier.” Strong evidence suggests that vitamin D intakes well above current recommendations are beneficial, and when combined with calcium, have a significant impact on overall bone health.
Vitamin D plays a crucial role in supporting:
- Healthy gene expression
- Proper brain and nervous system function, growth, and development
- Healthy hormone levels
- Regulation of the immune system
- Glutathione levels
- Reduction of oxidative stress
- Healthy inflammation levels
- Bone integrity and development
Why is Vitamin D3 Your Best Flu Defense Tool?
Vitamin D has been the subject of numerous studies for its effect on the immune system by promoting phagocytosis and immunomodulatory functions. Cold and Flu season is vitamin D deficiency season. As vitamin D levels severally drop from less exposure to sunlight the incidence of colds and flu in the winter dramatically increases.
Supplementing with vitamin D is scientifically proven to prevent colds and flu.
Here are a few of the many studies which prove vitamin D3 is the most effective defense from the seasonal flu.
Perhaps one of the best known studies was by Cohen et al. in 1991 where they exposed ALL subjects to the cold virus but only those who were "stressed" developed a cold!
Cohen, S. et al. Psychological stress and susceptibility to the common cold. N. Engl. J Med 1991 Aug 29; 325 (9); 606-612.
“Solar radiation (sunlight) triggers robust seasonal vitamin D production in the skin; vitamin D deficiency is common in the winter, and activated vitamin D - 1,25(OH)2D, a steroid hormone, has profound effects on human immunity.”
Cannell, J. et al. Epidemic influenza and vitamin D. Epidemiol Infect. 2006 Dec;134(6):1129-40.
Vitamin D dramatically increases the expression of antimicrobial proteins (AMPs) in cells of the innate immune system (the part of the immune system that immediately attacks and kills viruses, bacteria, and fungi).
Heaney, R. Vitamin D in health and disease. Clin J Am Soc Neph. 2008. Vol 3(5):1535-1541.
Countries with the highest blood levels of vitamin D from supplementation have the lowest incidence of seasonal cold and u and half the winter mortality rates.
Cannell, J. et al. Epidemic in uenza and vitamin D. Epidemiol Infect 2006, 134(6):1129-1140.
A randomized, double blind, placebo-controlled study reported that children taking Vitamin D3 daily in winter were 67% less likely to get unfluenza (H1N1 varieties).
Urashima, et al. Randomized trial of vitamin D supplementation to prevent seasonal in uenza in schoolchildren. Am J Clin Nutr. May 2010. Vol 91(5):1255-60.
In a three year trial supplementing with Vitamin D reduced the incidence of colds and flu by 70%.After two years they increased the amount of vitamin D intake and reached nearly a 100% prevention rate for colds and u (only 1 of 104 subjects developed cold or flu final year).
Aloia, J et al. Epidemic in uenza and vitamin D. Epidemiology and Infection. 2007. Vol 135(7):1095-1098.
On the basis of studies reviewed to date, the strongest evidence supports vitamin D therapy for influenza ( u) and viral upper respiratory tract illnesses (colds).”
