Yes, however...: Normal levels of Vit D are 30-100, though 50-80 is the optimal level. Achieving good levels helps prevent heart disease, cancer, autoimmune disease, infections etc. In fall & winter all adults should take 5-8000 iu/day. In spring and summer spending about 20 min. in mid-day sun without sunscreen can give enough D but if you don't do that take year-round. Best with K. Many good brands- see comment:

Ideally take Vitamin K with D; D helps us to absorb Calcium and K makes sure the Calcium winds up in the bones and not in arteries. There are many good brands; choose Vit D3 (not D2). I like liquid drops with 2000 iu/drop but if you find capsules that combine 2000-5000 iu with Vit K in same capsule that would be good too.
