Reliable product
I appreciate that this is a physician therapeutic quality item. I appreciate that it is available in 5,000 IU form (so that I don't have to take a bunch of lower dose pills in order to get this therapeutic dosage).

Effective product. Amazon not the cheapest source.
This product was recommended by my Dr. I usually buy it at his office. If I run out between visits I buy it at Amazon. Must say the Dr office sells it for a significantly cheaper price. My Vit D levels have reached normal on this product.

Vitamin D is the best defense
This is pandemic armor. If you want respiratory defense this is it. Vitamin d helps with hundreds of functions. It helps prevent certain autoimmune diseases (like diabetes, MS) and cancers. It helps with depression and cognitive functions. You need it every day. If you’re not going outside, take a supplement. Your body needs it.
