Product Overview

Sunlight is the source of life on Earth, but we may not be aware of all the ways it benefits use. Our bodies manufactured vitamin D-3 when the skin is exposed to UV radiation from sunlight, but its ability to do so decreases as we age.

No more colds or flu

Posted by iJenNZ on Jul 30, 2012 | Verified Purchase

I am taking one capsule per day of this product, in consultation with my doctor, and blood tests show that it is maintaining my vitamin D level in the upper normal range. At this level I can get through winter without contracting any cold or flu viruses that previously had been making me very ill. A definite thumbs up for this product.

Thanks for your feedback!

Best vitamin since sliced bread!

Personally Vit. D3 works only in mega doses, three times daily.
