ProHealth's high potency 50000 IU D3 Extreme™ 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.

Solomon I.
Highest dosage of Vitamin D3

I've been taking Vitamin D3 Extreme for several years now as it was recommended by my doctor. I wasn't able to find the 50,000 IU capsules at any of the local retail pharmacies but was able to order it from ProHealth. It gives me the right amount of Vitamin D3 which I just take every other week to keep my bones strong.

Happy Survivor

I switched over to ProHealth brand, and have been taking that for many years, setting up an automatic delivery of two bottles every two months. I share extra bottles with family and friends.
The vitamins arrive regularly, and there have been no problems with my orders.
