  • Super-potent bone nutrition

  • Works to absorb and use calcium efficiently

  • As seen in Woman's World

  • ConsumerLab.com 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 5 out of 5 by it works The vitamin d council has a lot to say about dosage of vitamin d3 (which is the best form). We are spending less time in the sun, and covering up with sun block when we do. It is a very important supplement. March 22, 2012

Rated 5 out of 5 by A good source of vitamin D! This is a very convenient and economical product which allows one to greatly increase the amount of vitamin D in the diet. It is especially noteworthy that this formula offers the dry version which may be preferable to other versions. February 15, 2012
Rated 5 out of 5 by MUST BUY!!!!!!! I do Muscle testing (Kinesiology) and Teach Holistic Nutrition. I have tested Numerous brands of Vitamin D-3. From the Very Expensive, (some sold by prominent Naturopaths) to the Very Inexpensive. And I have found that FEW are ANY GOOD. This Product is the BEST! and Very low Cost!! I have seen amazing results, in a very short time. It's the one I recommend to All My Clients, Family and Friends. Most other brands are JUNK, and very costly because of the HYPE . God Bless You Swanson's for all your great Quality products! March 17, 2010
