  • 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.

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
teriffic product! this helps SO much with energy! December 30, 2013
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
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
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
So many people deficient in Vitamin D! This is the best D supplement I've come across! Fantastic price as well! November 18, 2013
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
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
Works For Me Does what it is supposed to do, for an excellent price. Definitely recommend. August 31, 2013
good value great value for great product! August 31, 2013
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
I take it once a day with my calcium, do not know how it works, but I am feeling great. August 7, 2013
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
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
It's D As we get older you need the D....but with Swanson it's cheaper. Thanks July 10, 2013
Dry Vitamin D I don't absorb fats very well. By labwork at my doctor's office, my Vitamin D level was very low. I took other brands of regular Vitamin D, and there was no improvement in my labwork. Just throwing my money away. So I started to take this "dry" vitamin D from Swanson. It absorbs better. Follow-up labwork shows that my level is now within normal levels. I can feel a difference when I'm taking this. The value is great! Much cheaper than other brands, but my labwork says that this is a great product. Thank you! July 4, 2013
Great Value Previously had a problem with low Vitamin D levels, my levels improved dramatically after taking two to three capsules daily depending on the season. Very happy with the quality of this product as well as the price. Would definitely recommend this product to a friend. July 2, 2013

Did the Job A recent visit to my doctor revealed that my Vitamin D level was low. I started taking the High Potency Vitamin D-3. within two months, my levels were normal. May 11, 2013
High Potency Vitamin D-3 During the fall and winter I experience a dragged down feeling mainly due to the lack of sunshine. After taking this product I feel fantastic! It is a must have for me since I live in the northern US. If you have the same feeling, give this a try and see how you feel! ELbee April 30, 2013
