--- Comment by the founder of VitaminDWiki * Probably would have had much more weight loss if had repleted Vitamin D BEFORE the diet and exercise portion of the program. * The Vitamin D would have been virtually useless in the first month or two of this 3-month program * Repletion can take 8-12 weeks if given bi-weekly (1,200,000 = 12 week X 100,000 IU) * Repletion <2 weeks if given all within a single week (e.g. 170,000 daily) --- 1.
