One thought on “How Do You Know If You Have a Vitamin D Deficiency?”
Arti says:
A vitamin D deficiency can only be discovered through blood tests that measure levels of storage vitamin D, known as 25(OH)D. In the US, current guidelines suggest that consuming 400–800 IU (10–20 mcg) of vitamin D should meet the needs of 97–98% of all healthy people (12). While it’s possible to take too much vitamin D, toxicity is very rare.
