ProHealth's highest 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.

D3 Extreme

Great product!

Definitely a must living in Seattle. 🙂

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.

Good product

Great supplements. Good quality, but I like the gel pills better because they are smaller and easier to swallow. That's the only reason I didn't give it a 5.
