Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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!
