Vitamin D functions as a hormone, a chemical messenger with widespread effects in the human body. It is important for optimal bone, cardiovascular, neuromuscular, and immune health. Adequate calcium and vitamin D throughout life, as part of a well-balanced diet, may reduce the risk of osteoporosis. Supplementation with vitamin D may be necessary to meet daily needs, since obtaining sufficient vitamin D from natural food sources and sun exposure alone can be difficult. Research shows that vitamin D3 (cholecalciferol) is approximately 87% more potent than vitamin D2 for raising and maintaining vitamin D blood levels.

Well engineered, physician's enthusiastic approval.
This is a quality product, reasonably priced for what it offers, and highly recommended by my doctor. I've been using it for two years, no side effects of any kind. I would endorse it with confidence.

The Best Vitamin D3!
I learned about this brand of vitamin D3 from the Vitamin D Council and have twice now raised my D levels from severe deficiency (7 and later 3) to optimal levels between 80-100. I now take a weekly maintenance dose of 5K/week as a maintenance dose to avoid becoming deficient again as I appear to be chronically vitamin D deficient without supplements. I’m happy, my doctor is happy, and I highly recommend this brand of vitamin D3!Incidentally, my PCP had given me a prescription for vitamin D after my level came back at 7. I filled the script but also started doing research and discovered she had prescribed vitamin D2. As soon as I got the Bio-Tech Pharmacal D3 I stopped taking the prescription vitamin D2 because the test measures vitamin D3! She was amazed with how quickly I raised my levels but refrained from telling her how I did it. I’ve learned the hard way that most doctors really resent it when their patients know more than they do!

Great product, reliable company so far, good type of Vit D to take as well.
Great Product. We have used this for years after our doctor said this Vit D product showed up in increasing his patients Vit D blood levels. We like it and my husband feels it helps his body pain go down some and also boots his immunity. Good value as well for the money.
