Comment: You're risking vitamin toxicity here.

(See in situ)

You're risking vitamin toxicity here.

5,000 IU / day is above even the Tolerable Upper Limit for adults, and five times that for infants up to 6 months. You're risking vitamin toxicity here. Granted it's substantially below the levels that have been shown to produce ACUTE toxicity, but playing with megavitamin levels during childhood body development is, IMHO, big-time risky.

Has anyone died of vitamin D toxicity? Given that (especially in people of African descent) it can accelerate atherosclerosis, I'd say "You bet your life!"

But even if not, I'll be happy to skip the Dehydration, Vomiting, Decreased appetite, Irritability, Constipation, Fatigue, Muscle weakness, Metastatic calcification of the soft tissues, Kidney stones, ...

Unlike skin synthesis of vitamin D under ultraviolet light, which is largely self-regulating, dietary intake raises the blood levels of it and its metabolits substantially. Research shows that there is a rather narrow range of blood levels, outside of which (high OR low) the arteries age more rapidly and the death rate rises. Do YOU want to bet your, or your child's, life on whether this death rate rise is an effect of other disease process munging the blood levels and never excessive intake of dietary D3?
