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
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
Great value Best value for this necessary product! September 11, 2013
