  • Provides super-potent bone nutrition

  • Works to absorb and use calcium efficiently

  • 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 4.8 out of 5 by 157 reviewers.
Rated 5 out of 5 by Very small in size I really like this product, they are very small in size & big on quality September 8, 2016
Rated 5 out of 5 by Great Product My Dr. said I am deficient in this vitamin so I ordered it from Swanson's because I thoroughly trust them. July 21, 2016
Rated 5 out of 5 by Recommended by my Dr. My Dr. recommended that I purchase all of my vitamins and supplements from Swanson Vitamins. He said that they are of the highest quality with the best cost. Thank you for having such wonderful products!!!! February 25, 2016
Rated 5 out of 5 by Works for Appetite Control! I bought this a few winters ago because of all the hype on vitamin D. My husband and I didn't notice any 'wow' when taking the first bottle. We ran out, and I did not intend to repurchase. A few weeks later we both noticed a significant increase in appetite. We finally figured out it was due to the vitamin D. We bought another bottle, and soon our appetites were under control-no more munchies and satisfied with smaller portions. We tried an expensive kind, one in olive oil, and never noticed an improvement over the Swanson's brand, so we are back to stay. October 4, 2015
Rated 1 out of 5 by Anything in There? I take one of these daily and its supposed to be 2 1/2 times the daily allowance but my last lab test showed a Vit D deficiency! So I question whether it has the claimed amount of Vit D (or any at all). October 3, 2015
Rated 5 out of 5 by Use as extra boost to 5000 mg Vit D3 I purchase this to use if I want to use just a bit more than my 5000mg gel cap. It is a very small capsule which I like. Happy with this product! September 25, 2015
Rated 5 out of 5 by This is a great product This brought my Vitamin D level back up to a normal rate. I will continue to take it all the time. I think Swanson is the best place to get vitamins, their great prices keep me coming back. March 21, 2015
Rated 5 out of 5 by Meets my needs These supplements help keep my Vitamin D level where it should be & I feel they are a good value too. December 21, 2014
Rated 5 out of 5 by Swanson's High Potency Vitamin D-3 If you're looking for a high dose source of Vitamin D-3, then all I can say is here it is. Safe and effective. I work graveyard, indoors for 10-12 hours, and sleep much of the day away, so sunlight is rare for me. This helps, especially since I'm getting into my 50's. If this is too high for you, then go with the 400 I.U. instead, also available right here at Swanson. September 16, 2014
Rated 5 out of 5 by Very good It is a vitamin that I take daily on recommendations. May 31, 2014
Rated 5 out of 5 by Highly Recommend Vit. D-3 No matter where you live, I believe it's very important to keep tabs on vitamin D levels. This is such an easy & convenient way to meet your daily need of this important vitamin. February 7, 2014
Rated 4 out of 5 by teriffic product! this helps SO much with energy! December 30, 2013
Rated 5 out of 5 by I trust Swanson. I trust Swanson to give me a great product at a great price. I am confident with their D3. December 18, 2013
Rated 5 out of 5 by Great Product! I have been taking this for quite a while. When I started ,my blood work showed that I was deficient in vitamin D. My levels were single digit. After taking 4 a day for a while, the next time I had blood work done it showed that my D was too high. So I cut back to 2 a day and my D level stays great. I know that it worked for me. Suggest you have your blood work check your vitamin D level and dose accordingly. This is a great product if used properly. December 8, 2013
Rated 5 out of 5 by effective this product is effective. It brought my vitamin D level up from below minimum to very good. I used 4 caps per day December 4, 2013
Rated 5 out of 5 by So many people deficient in Vitamin D! This is the best D supplement I've come across! Fantastic price as well! November 18, 2013
Rated 5 out of 5 by Special Find I especially like to take vitamins in the dry formula since the gels do not agree with me. It is the only dry vitamin D I have found and I am very pleased with all of its qualities and also the price. Since Vitamin D is so essential I believe I have discovered a "special find" I have been using it for years. November 3, 2013
Rated 5 out of 5 by D3 I like the 1000 IU for this product . I don't like having to take multiple pills just to get the right dose. This is very convenient to use. October 31, 2013
Rated 5 out of 5 by Works For Me Does what it is supposed to do, for an excellent price. Definitely recommend. August 31, 2013
Rated 5 out of 5 by good value great value for great product! August 31, 2013
Rated 5 out of 5 by Vitamin D-3 1000 IU This is a good quality Vitamin D-3 capsule for the money. I like the capsules because there is no problem with them dissolving. Great product. August 21, 2013
Rated 5 out of 5 by I take it once a day with my calcium, do not know how it works, but I am feeling great. August 7, 2013
Rated 3 out of 5 by wrong form for me I didn't look closely when buying this. I prefer the gel tab form of D at a higher concentration. August 4, 2013
Rated 5 out of 5 by maintain daily Vitamin D !! I love this 1,000 units size -- that way we can take them 4 different times daily to keep levels in the body up more often. July 29, 2013
Rated 5 out of 5 by It's D As we get older you need the D....but with Swanson it's cheaper. Thanks July 10, 2013
