In Cebus albifrons monkeys it was demonstrated that vitamin D3 promotes the intestinal absorption of calcium-47 and that vitamin D2 does not increase absorption above that seen in monkeys deficient in vitamin D. These data support previous observations that vitamin D2 is not effective in preventing metabolic bone disease in this species.
