ProHealth's high potency 50000 IU is the strongest single dose on the market at a cost far less that you would pay at a pharmacy. We developed this product using vitamin D3 or cholecalciferol, which is the same type of vitamin D your body makes when exposed to sunlight and it is also the version used to fortify foods.

Excellent supplement

Vit D

My Vit D levels were low but after taking this for 2 months my levels were at the high range, works well. I did take with Vit K for absorption.

Cynthia C.

My script for this amount of D3 was no longer covered by my insurance. Found your site for the same amount (50,000 IU) ordered it and I am pleased.

Renee F.
Great vit d

Pro health always ships this out fast. These are great if you take a high dose of vitamin d and are small and easy to swallow. Always buy my vit d from pro health.
