So much brouhaha about vitamin D these days. How much do we need? What levels are are dangerous? What does vitamin D really do for us?
Leila Sladanha, PhD, RD reports that vitamin D is a prohormone, which, when activated, acts as a hormone. It is mainly known for its role in bone health, but there is growing evidence that vitamin D deficiency may contribute to increased risk of chronic diseases, including cardiovascular disease and some cancers.
There is conflicting opinion on mega-doses of vitamin D, but there is evidence that levels above 4000 IU per day are associated with increases in all-cause mortality.
Check with your doctor before taking high doses of vitamin D.
Me? I take about 2000 IU on average per day. So far, I'm fine.
