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.

Difficult to swallow

The capsules are so large that I have an hard time swallowing them, so I rarely take them. I would not recommend this product.

Joy S.
D3 Extreme

At first I was alarmed by the high dose but tried it as my doctor highly recommended it. It works so well that I have now made it a part of my supplement routine.

Recommended by my doctor

Great value. Good go-to product to keep the immune system bolstered.

D3 Extreme

Great product!

Definitely a must living in Seattle. 🙂

Eric A.

We find taking one of these tablets every 10 days keeps our vitamin D at the correct levels. Buying in packs helps reduce the cost and storage in the fridge is ok. A great product.

Pat K.

Ive been using this product
