An article published in the Oct. 2009 edition of Nature Reviews: Endocrinology highlights that supplementation with the currently recommended vitamin D levels of 400 IU falls well short of being effective.
The article was written by Dr. Bruce Hollis, a respected researcher that has published numerous articles on vitamin D and its role in cardiovascular disease, cancer, osteoporosis and more. Do any sort of search on vitamin D and chances are good that his name will come up.
Hollis discusses how the current recommendations of 400 IU don't do anything to increase serum (blood) levels of vitamin D. Vitamin D sufficiency (adequate levels) is defined as having vitamin D levels above 75 nmol/l. In one study, they found that 74% of postmenopausal women had levels lower than 50 nmol/l. Vitamin D levels this low are implicated in a number of diseases in epidemiological studies.
The graph below, taken from the article, shows how vitamin D supplementation below 1,000 IUs/day did not significantly increase serum levels of vitamin D.
To put this in plain English:
When you take vitamin D supplements that provide a daily dose of less than 1,000 IU you are paying for nothing, literally.
BoneMate Plus provides you with 4,000 IU of quality vitamin D3, as well as calcium and other minerals that help the body to utilize and better absorb calcium.
Dosage studies show that it is best to space out your calcium supplementation - as more will be absorbed this way. We recommend that you take BoneMate Plus in the morning and then at night.
