Rated 4.8 out of 5 by 13 reviewers.
Rated 5 out of 5 by vitamin D This is a great supplement and gets a thumbs up from me. May 1, 2016
Rated 5 out of 5 by Tiny and Mighty There are so many health benefits associated with Vitamin D. It's very important to get adequate amounts. Easy to swallow and great value. December 21, 2015
Rated 5 out of 5 by Doctor's Best Vitamin D3 I wish that Swanson offered a small, 1000 IU D3 gel like this, however, this is a very good brand, and I would recommend it if you are Vitamin D deficient. Though I probably need more, one gel, twice a day, several hours and meals apart is all my tummy can handle of any brand of D. September 27, 2015
Rated 5 out of 5 by Great Product This product has worked well to bring my husband's vitamin D3 level in a good range. He took a higher dose with the Swanson label and it didn't help. May 23, 2015
Rated 5 out of 5 by Affordable and well absorbed I have researched the best vitamin D since mine runs low in the winter. As a Registered Dietitian I use and recommend this product. November 26, 2013
Rated 5 out of 5 by Great D3 I bought this because there is NO Soy OIL in it like the vitamin D3 that the pharmacy sells. I wanted to up my D3 intake to improve my immune system, so I take one 1000 iu soft gel at breakfast and another one at dinner. I noticed within the week that I had more stamina and I am more cheerful. I'm not surprised since D3 works in hundreds of enzyme systems in the body. Awesome stuff! November 12, 2013
Rated 5 out of 5 by Great value Best value for this necessary product! September 11, 2013
Rated 4 out of 5 by Dr.s Best D3 For the money it is about the best deal out there. Not a knock off brand either. Well worth the price. May 2, 2013
Rated 5 out of 5 by great value To have the Doctor's Best name and a great price, you can't go wrong with this.Vitamin D is needed by everyone and this does the job for me! February 10, 2013
