Vitamin D recommendations
While these studies are promising, they aren’t conclusive. What we know for sure, though, is that vitamin D is crucial for our health—and many of us aren’t getting enough of it.
The National Institutes of Health (NIH) generally recommends that adults get 600 IU of vitamin D per day—unless you’re over the age of 70, in which case you should aim for 800 IU. However, other experts suggest that up to 1,500 to 2,000 IU of daily vitamin D is best for optimal well-being.
