In this new study, a team of researchers at the US Children's Nutrition Research Center in Houston studied vitamin D levels and calcium absorption in 251 healthy children aged 5 to 16. They recorded 439 vitamin D measurements taken over a period of 15 years.
Overall, vitamin D was significantly associated with the total amount of calcium absorbed.
However, in pre- or late puberty this relationship was no longer significant leading researchers to conclude that the overall effect of vitamin D levels on calcium absorption is small.
In children, there is a complex relationship between the level of vitamin D in the blood and how much calcium is absorbed with no simple answer as to how much vitamin D will lead to the most amount of absorbed calcium, report the scientists in the Journal of Clinical and Endocrinology & Metabolism.
