ProHealth's prescription strength 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.
With over 70% of the population deficient in Vitamin D levels it is important that you supplement your diet with a high-quality D3 vitamin. Each day we are learning more about the amazing benefits of Vitamin D.
A growing body of research suggests this powerful nutrient may:
Promote a healthy immune system
Boost calcium & phosphorus absorption and for healthy bones and teeth

I took it for unrelenting back pain. I took the correct K2, Mg, and Calcium to balance the high dose D3, 50,000 IU and 100,000 IU. I noticed reduction in pain by half the first day (50,000 IU) by third day of 100,000 and 50,000 IU D3 with K2, 5g and 10 g, Mg (not oxid
e) and Coral Calcium pain was gone. The proper amount of K2 seemed crucial as I tried it with less and did not get the full result until I added more K2.

Taking Vitamin D3 helps me with fatigue/weakness issues more than anything else I have ever taken. Without supplementation, my D3 levels are always below normal. I am extremely thankful for this supplement as it greatly improves my quality of life. It takes away the
"rubber feeling" in my legs and arms, gives me energy to complete many more tasks than I could wihtout it. When my D3 level is low, I have trouble with heart arrhythmias. They totally stop when I take sufficient Vitamin D3. It is important to have Vit D3 levels followed by a physician....[read entire review]

ProHealth always delivers promptly and keeps me informed regarding my order progress. The product is neat, clean and works well. In Australia I can only get 1000 IU caps, so this product means I only need 1 capsule per week !! I am well, and rarely get colds and other a
ilments now....[read entire review]

My doctor told me I needed to raise my vitamin D count. This did the trick.

I love D3 extreme, as I can just take one pill a week to get my vitamin D, rather than having to take them every day. I take enough pills and supplements every day, so I find this VERY helpful.
Plus, when I feel a cold or flu coming on, I will take one of these every d
ay for three days to rev up my immune system, and can usually avoid getting really sick....[read entire review]

Super potent vitamin D-3 product, the strongest I have ever seen. Very pleased with the convenience of having to take it only once a week or even once a month.
