  • As seen in Woman's World

  • approved vitamin D supplement

Swanson Vitamin D-3 is an essential bone supporting vitamin that works to absorb calcium efficiently in the body.* The body manufactures some vitamin D on its own when it is exposed to sunlight, but for people living in the northern latitudes where wintertime sun exposure is limited, the body's natural vitamin D may often be insufficient. Our High Potency Vitamin D-3 capsules tackle this problem by supplying an impressive 1,000 IU of vitamin D-3, the most biologically active fraction of vitamin D.


Q: Why are these considered dry?
A: They are considered dry because the vitamin D-3 is not suspended in a liquid oil; rather, it is in a dry powder inside the capsule.

Q: Is the Vitamin D-3 in this supplement sourced from fish or lanolin?
A: It is from lanolin.

Rated 3 out of 5 by from Not potent enough I took this "high potentcy Vitamin D3 for more than 1 year, and I was still deficient in Vitamin D. My doctor told me to take 5,000 IU of Vitamin D3 daily. I am 80 years old, so I require more D3 supplement, but I will not be ordering this again.

Rated 2 out of 5 by from D3 supplement I should have gotten at least 10,000 IU. These are not really high potency, not for D3 I have to take way too many of these to make it a good value for me. My fault, I should have paid closer attention to the strength not the title.

Rated 5 out of 5 by from Vitamin D3 I live in the north and had low vitamin D levels. Take this product every day and it's raised my vitamin D levls. Great product!
Date published: 2013-06-23
Rated 5 out of 5 by from Great all around bargain It's hard to say about Vitamin D products until one gets a Vitamin D test done, but this appears to be a fine health support for the benefits of Vitamin D3. Can't beat the price.
