You may not be getting enough Vitamin D!


Read a very good. very detailed article at the above address. Basic recomendations from article are below:

Linus Pauling Institute Recommendation

The Linus Pauling Institute recommends that generally healthy adults take 2,000 IU (50 mcg) of supplemental vitamin D daily. Most multivitamins contain 400 IU of vitamin D, and single ingredient vitamin D supplements are available for additional supplementation. Sun exposure, diet, skin color, and obesity have variable, substantial impact on body vitamin D levels. To adjust for individual differences and ensure adequate body vitamin D status, the Linus Pauling Institute recommends aiming for a serum 25-hydroxyvitamin D level of at least 80 nmol/L (32 ng/mL). Numerous observational studies have found that serum 25-hydroxyvitamin D levels of 80 nmol/L (32 ng/mL) and above are associated with reduced risk of bone fractures, several cancers, multiple sclerosis, and type 1 (insulin-dependent) diabetes.

Infants should have a daily intake of 400 to 1,000 IU (10 to 25 mcg) of vitamin D, and children and adolescents should have a daily intake of 600 to 1,000 IU (15 to 25 mcg) of vitamin D, consistent with the recommendations of The Endocrine Society (99). Given the average vitamin D content of breast milk, infant formula, and the diets of children and adolescents, supplementation may be necessary to meet these recommendations. The American Academy of Pediatrics currently suggests that all infants, children, and adolescents receive 400 IU of supplemental vitamin D daily (19).

Older adults (> 50 years)

Daily supplementation with 2,000 IU (50 mcg) of vitamin D is especially important for older adults because aging is associated with a reduced capacity to synthesize vitamin D in the skin upon sun exposure.

Vitamin D3 "87 percent more potent" than D2: Study

By Stephen Daniells, 11-Jan-2011



Vitamin D3 is 87 percent more potent at raising blood levels of the vitamin than vitamin D2, according to a new study from the US.

In addition to the increase in potency, results published in Journal of Clinical Endocrinology & Metabolism indicate that vitamin D3 also produced a 2- to 3-fold increase in the storage of the vitamin, compared with vitamin D2.

Scientists led by Robert Heaney, MD, from Creighton University in Nebraska supplemented 33 health adults with 50,000 International Units (IU) of either vitamin D2 or D3 per week for 12 weeks. Results showed that about 17 percent of the D3 ingested was stored by the subjects, and the rest was consumed or metabolized or both.

“This is a daily utilization rate of about 6500 IU at a [blood vitamin D] concentration of 50 ng/ml at the end of treatment,” write the researchers. Optimal levels of vitamin D are considered to be between 50–80 ng/mL.

“At the doses used in this study, most vitamin D is metabolically consumed. This is the first study, to our knowledge, to have quantified this issue,” added Dr Heaney and his co-workers.

Shining light on the sunshine vitamin

Vitamin D refers to two biologically inactive precursors - D3, also known as cholecalciferol, and D2, also known as ergocalciferol. Both D3 and D2 precursors are transformed in the liver and kidneys into 25- hydroxyvitamin D (25(OH)D), the non-active 'storage' form, and 1,25-dihydroxyvitamin D (1,25(OH)2D), the biologically active form that is tightly controlled by the body.

The relative bioavailability of the two forms of vitamin D is an area of intense interest and debate. Several studies have reported that vitamin D2 is between 30 and 50 per cent less effective as the D3 form in maintaining blood levels in humans. On the other hand, a 2008 study by Boston University researchers reported that both forms are equally effective at maintaining 25-hydroxyvitamin D status (Journal of Clinical Endocrinology & Metabolism, Vol. 93, pp. 677-681).

New data

Dr Heaney and his co-workers acknowledge the inconsistencies in the literature, and attempt to “clarify this issue”. Thirty-three healthy adults with an average age of 49.5 were recruited and assigned to receive weekly doses of vitamin D2 (Banner Pharmacaps, Inc.) or vitamin D3 (BTR Group, Inc.).

After 12 weeks of supplementation with 50,000 IU of vitamin D, the researchers report that levels increased significantly more in the D3 group than in the D2 group.

“By the various measures employed, D3 was from 56 to 87 percent more potent than D2 in raising serum 25(OH)D, and more than three times as potent in increasing fat calciferol content,” stated the researchers. “[T]hese results can, we believe, not only safely be generalized to routine clinical practice, but also are pertinent to what clinicians are actually prescribing.”

Dr Heaney and his co-workers noted that their results are limited by the relatively short duration of the intervention, and by their methods, which approximated vitamin D content in total body fat by extrapolating from a measure of percentage fat. “Hence, a longer study with multiple fat biopsies would be in order,” they added.

“Given its greater potency and lower cost, D3 should be the preferred treatment option when correcting vitamin D deficiency,” concluded the researchers.
