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.

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.

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.

Trying to reduce the amount of tablets I take. High IU in one dose. Very happy

Great product

Quick turnaround on my order.


Was diagnosed with low VitD several months ago. Insurance won't pay for a vitamin and the prescribed version was pricy. Switched to ProHealth's and my blood test shows my levels are back to normal. Not bad for a 71 year old.
