v = VITAMIN D-EFICIENCY


How soon we forget! Children are taught in first grade that Vitamin D is the "sunshine vitamin." Vitamin D is a steroid hormone and is synthesized in one's body after skin is exposed to sunlight. Once the body has made enough, it will produce no more. Too much Vitamin D can be toxic and lead to bone loss.


"Exposure to sunlight provides most humans with their vitamin D requirement."

Journal of Nutrition 1996;126(4 Suppl)


"Adults need 10-15 minutes of sunlight, two or three times a week to ensure proper Vitamin D levels."

Journal of Pediatrics, 1985; 107 (3)


"Consuming as little as 45 micrograms of Vitamin D-3 in young children has resulted in signs of overdose." (one quart of milk contains 400 IU, or 10 micrograms)."

Pediatrics, 1963; 31


"Testing of 42 milk samples found only 12% within the expected range of Vitamin D content. Testing of 10 samples of infant formula revealed seven with more that twice the Vitamin D content reported on the label, one of which had more than four times the label amount. Vitamin D is toxic in overdose."

New England Journal of Medicine, 1992, 326


"Vitamin D increases aluminum absorption, and high aluminum levels in the body may cause an Alzheimer's-like disease."

Canadian Medical Association Journal 1992 147(9)


"Eighteen breast milk and 17 formula-fed infants, ages 2 to 5 months were studied. The serum 25-hydroxyvitamin D (Vitamin D) level was significantly lower in breast milk- than formula-fed infants but bone mineral content was not different. This demonstrates adequate mineral absorption occurs from a predominantly vitamin D-free transport mechanism."

Journal of Pediatrics, 1998 Apr, 132:4


"To investigate whether greater intakes of calcium, vitamin D, or milk products may protect against ischemic heart disease mortality, data from a prospective cohort study of 34,486 postmenopausal Iowa women were analyzed... results suggest that a higher intake of calcium, but not of vitamin D or milk products, is associated with reduced ischemic heart disease mortality in postmenopausal women."

Am J Epidemiol, 1999 Jan, 149:2


"It has since been discovered that the Vitamin D necessary to absorb the calcium moving down the intestine must already have been in the bloodstream for a while; what is present with that calcium (in milk) is useless at that stage. Vitamin D is part of the mechanism to break bone down so that it can then stretch and grow. Thus an overdose of D can eventually lead to osteoporosis."
