  • Highest potency vitamin D supplement

Swanson Premium high Potency Vitamin D-3 5,000 IU is our highest potency vitamin D supplement available. Americans need more vitamin D, and experts across the country are calling for changes to the RDA and suggesting that a majority of us are not getting enough. Vitamin D is vital to healthy bones, strong immune system functions and mental/emotional wellness. Sunlight helps our bodies produce vitamin D, but our production capacity is limited...especially in winter months when sun exposure is reduced.

The current RDA for vitamin D is between 200 IU and 600 IU for the average person based on age, weight and health status. But most experts now recommend that healthy individuals take in up to 1,000 IU on top of what they might get through diet and multivitamins. Those in Northern climates or with greater needs may need even more. Our new 5,000 IU vitamin D-3 softgels answer the need for those who require higher intake.

Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Rated 4.9 out of 5 by 205 reviewers.
Rated 5 out of 5 by Affordable and Effective This product is very affordable and easy to take - the gel caps are quite small. My recent blood work showed a healthy level (and a higher level than previous Vitamin D tests showed) for vitamin D which I believe is in part due to taking this product. January 1, 2017
Rated 5 out of 5 by A great choice for vitamin D My doctor suggested I take a Vitamin D supplement. I chose Swanson's 5000 IU, and I am very happy with this choice. The price is very reasonable and the ingredients are of superb quality. November 16, 2016
Rated 5 out of 5 by Liquid sunshine I always feel better when I take these in the winter. October 19, 2016
Rated 5 out of 5 by Very absorbable! I have been taking this for a while and recent blood work showed a significant increase in my Vitamin D-OH 25 levels. This tells me that the Swanson brand is a quality product and very absorbable. I would recommend this to anyone wanting to supplement their Vitamin D. October 16, 2016
Rated 5 out of 5 by Vitamin D It's worked very well for me. I am now in normal range for vitamin d instead of very low! July 17, 2016
Rated 5 out of 5 by I've been using this product for some time, but just recently check on the vitamin D3 level I need for my age, and discovered that I was not taking enough; Upon checking, I discovered the product in a higher potency. All Swanson products are reliable and reasonably priced. June 5, 2016
Rated 5 out of 5 by Combined with Vitamin k-2, it really helps replenish my bone mass. May 15, 2016
Rated 5 out of 5 by Great Value Swanson's SW HIGHEST POTENCY VIT D-3 5000 IU 250SG is easy to take because it's very small gel cap but has a very high potency of vitamin D. April 23, 2016
Rated 5 out of 5 by Good vitamins These were exactly what I need and they were a little cheaper than a couple other places that I checked February 17, 2016
Rated 5 out of 5 by D-3 It is a relied to now be able to get my full dosage in one pill. Great. January 16, 2016
Rated 5 out of 5 by Vitamin D-3 5000 IU My wife and I take one of these soft gels at both breakfast and lunch. Dr. Micozzi and Dr Pescatore as well as many other health newsletter writers have noted many studies showing the health benefits of taking 10,000 IU per day. December 28, 2015
Rated 5 out of 5 by Vitamin D-3 5000 IU During the winter months I like to ramp up my Vitamin D-3 supplement to 5000 IUs and Swanson has it at a great price point. December 5, 2015
Rated 5 out of 5 by Effective Vit D My vitamin D levels were low according to my doctor. Started taking these easy to swallow caps once daily and now my Vit D level is high normal range. November 15, 2015
Rated 5 out of 5 by Important nutrient! Vitamin D's importance throughout our body has been underestimated for a LONG time! Now we know that it is very important in almost every single body process we have and the daily values needed has been raised (just not high enough in my opinion) so taking a supplement becomes critical to maximum functioning of our bodies in so many ways. November 4, 2015
Rated 5 out of 5 by A "must have" Some things are "subjective" (i.e. I can't literally measure Quality or Effectiveness on this. HOWEVER, Swanson has demonstrated to me that it is a great company. That being said, Vitamin D-3 is such a standard product, that I am Trusting that this is the best product for me, and an ESSENTIAL one! I do think "Value"/PRICE could be a bit better. Rather than 3.596 cents per capsule, my guess is that it could be produced for 2 to 3 cents per capsule. September 29, 2015
Rated 5 out of 5 by Good quality I love this product.I'm always low in vitamin D,so I have to supplement.Swanson has the best value and I love that they don't use soybean oil in the 5000 IU because I am allergic to soy. September 27, 2015
Rated 5 out of 5 by Super supplement! I love this little gel cap Vitamin D3! I Always keep on hand and regularly take 1-2 daily. I've heard we need more of this type of Vitamin D. It really helps the immune system, and other things as well! September 25, 2015
Rated 5 out of 5 by Great value Great value in an easy to swallow softgel. Best taken with vitamin k-2. September 11, 2015
Rated 5 out of 5 by Good product! When looking for any supplements, I always turn to Swanson! The best prices and products! August 21, 2015
Rated 5 out of 5 by great value large quantity, highest potency, and great results. August 20, 2015
Rated 2 out of 5 by Vitamin D did not improve After supplementing with this product my husband's vitamin D level did not improve. I switched him to another brand that Swanson carries and his level is now in the optimal range and the dose was only 1000 IU compared to this brand of 5000's IU. May 23, 2015
Rated 5 out of 5 by Good stuff Good stuff, small size makes it easy to swallow. Great value. Highly recommended. May 16, 2015
Rated 5 out of 5 by Good producti I like this product, it is a strong dose of Vit D3 in a small package. The softgels are quite small and easy to take. 5000 IU in a tiny softgel. I think it is good quality and you get your money's worth. I have no problem recommending this item. May 5, 2015
Rated 5 out of 5 by great supplement Living in the Northwest is not an easy pill to swallow most of the seasons, which lack sunshine. This new potent Vitamin D-3 is the best news, b/c I have to take less pills for more [ptency. May 1, 2015
Rated 5 out of 5 by Good for my family I first used it and let my mother (83) and mother in law (81) use it. Then I give it to my friends and hope that more people could get benefit from it. April 20, 2015
