Vitamin D, a fat-soluble vitamin, is essential to maintaining total body health, yet is not found in many foods. It's needed daily to keep bones and teeth strong over your lifetime, and to ensure the proper functioning of heart, muscles and nerves - it even helps your blood to clot. A daily regimen of this D3 (cholecalciferol) is the best way to treat and prevent vitamin D deficiency, whether from lack of sunlight, poor nutrition, chronic illness or aging.

D3 5000™ offers support for healthy bones by maintaining normal blood levels of calcium and phosphorus, thus promoting calcium absorption. It helps combat fatigue and assists the immune system with cellular growth regulation. An important formulation for those with low levels of vitamin D. Ingredients meet US Pharmacopeia standards.

Increase to 5000 IU

I've increased from 4 1000 IU gelcaps daily to just this one 5000 IU gelcap. This is the amount of D3 recommended by my endocrinologist, based on the best scientific reports, and the amount he takes himself

Multi Health Benefits From Vitamin D3

Vitamin D3 helps with multi functions in our bodies, immune system, stronger bone, telomere and DNA repair, steroid hormone and so forth. I've been taking it for several months. I remain physically strong all the times. We definitely can live healthier and longer life with vitamin D. Highly recommend it especially for those who get little exposure to sunlight.

Vitamin D3 5000 IU

Excellent product, but shipping to Canada very expensive now, so cannot afford it!🙃😥

Raised level of D

Several years ago, my MD thought my level of D3 was too low. I chose the ProHealth brand because I trust its quality and took it seven days a week. My level of D3 rose. Just recently my MD thought the level was a little too high, so I now take it six days a week. I have trouble with the fillers and binders in general and appreciate that I can take the ProHealth brand safely.

These are very good supplements. I take them daily and appreciate knowing that my vitamin D levels are maintained, even in the winter months.

I am very happy with this D3 supplement. I have restored my levels of 25D in a few days just with the recommended daily dose. Moreover, I had no issues with this supplement, great quality!

Great D3 supplement product.

I take several supplements produced by ProHealth, including this D3 supplement at 5000 IU. My annual blood test results never indicate any Vitamin D deficiency. I highly recommend this product.

Judith G.
Vitamin D3

Living in the northern region of North America, especially during the wintertime, it is extremely important to take Vitamin D supplementation as we are more house bound and have less hours of sunlight. This Pro Health Vitamin D3 is easy to take as they are in a tiny capsule form and very easy to swallow. Highly recommended.
