The Vitamin-D Table
Recommended Dietary Allowance (RDA): the average daily dietary intake level that is sufficient to meet the nutrient requirement of nearly all (97 to 98 percent) healthy individuals in a group.

•Adequate Intake (AI): a value based on observed or experimentally determined approximations of nutrient intake by a group (or groups) of healthy people—used when an RDA cannot be determined.

•Tolerable Upper Intake Level (UL): the highest level of daily nutrient intake that is likely to pose no risk of adverse health effects to almost all individuals in the general population. As intake increases above the UL, the risk of adverse effects increases.

•Estimated Average Requirement (EAR): a nutrient intake value that is estimated to meet the requirement of half the healthy individuals in a group.

“Following Dr. Holick’s advice about vitamin D is possibly the single most important thing you can do to improve your health and save yourself from many chronic diseases, including cancer.”

Mark Hyman, MD
DrHyman.com

“Dr. Holick shows us why if you do one thing for your health beside eating well and exercising it MUST be getting more vitamin D through sun or supplements. Vitamin D deficiency affecting 200 million Americans is not just important for building strong bones but is absolutely needed to prevent and treat our chronic disease epidemic including heart disease, cancer, diabetes, depression, obesity, and autoimmune disease.”

Christiane Northrup, M.D., ob/gyn

“Dr. Michael Holick has been a hero of mine for many years. How thrilling to have his ground-breaking research on vitamin D in one easily accessible book. This information can save your life. Really.”

It is also recognized that women who had the highest intake of vitamin D reduced their risk of developing multiple sclerosis by 41% and rheumatoid arthritis by 44%. Vitamin D deficiency has also been associated with peripheral vascular disease which is associated with the painful muscle cramping associated with activity. The Nurses’ Health Study at Harvard University revealed that women who had the highest intake of vitamin D reduce their risk of developing breast cancer by almost 50%.

I recommend to all of my patients that they should take 2000-3000 IU of vitamin D a day from dietary sources, sensible sun exposure and supplements. I believe that it is important for women to take at least 2000 IU of vitamin D a day. Although many of the studies are association studies there continues to be strong evidence that increasing vitamin D intake has other health benefits besides those for bone health. From my perspective there is no downside to increasing your vitamin D intake to levels I have recommended in The Vitamin D Solution which is 1000 IU of vitamin D a day for children and 2000-3000 IU of vitamin D for adults.

Vitamin D: Finding a balance
Vitamin D is likely beneficial for other parts of the body as well; studies suggest an overall decrease in death in addition to reductions in blood pressure, respiratory illnesses, cancer, heart disease, and depression. Vitamin D deficiency is very common and on the rise. This is mostly due to vigilant sun protection, since sunscreen with SPF 30 reduces vitamin D production by 95%. Too much vitamin D can be harmful, including (ironically) increasing fractures, falls, and kidney stones, and can be toxic by causing excessive levels of calcium. Although not proven, high vitamin D levels have been associated with prostate cancer, pancreatic cancer, and mortality. A recent study found that use of high-dose vitamin D supplements increased over a 15-year period.

So how much is too much? For adults, toxic effects increase above 4,000 IU per day. The recommended dietary dose of vitamin D is 600 IU each day for adults 70 and younger and 800 IU each day for adults over 70. To put this into perspective, 4 ounces of cooked salmon contains approximately 600 IU of vitamin D.. The recommended dietary dose of vitamin D is 600 IU each day for adults 70 and younger and 800 IU each day for adults over 70.

Very helpful & informative article indeed! And a 2O17 web posting by the University of Queen Mary London researchers also says that globally Vitamin D heips prevent colds & the flu…echoed nearby there by Dr. Mercola’s website posting that Vitamin D is better than the flu vaccine!
