"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." ~product review by Laryl

  • Super-potent bone nutrition

  • Works to absorb and use calcium efficiently

  • 1,000 IU of vitamin D-3 per capsule

Swanson Vitamin D-3 is the most biologically active form of vitamin D. 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 Vitamin D-3 formula supplies an impressive 1,000 IU of this essential vitamin. It works to support bone health by absorbing calcium in the body. Trial size bottle of Swanson Premium High Potency Dry Vitamin D-3 contains 30 servings.


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.

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
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
