    This is a vital addition to my medicine chest..

    This product is so extremely necessary in this climate..our rainy, cloudy weather doesn't allow for much exposure to sunlight. Partly cloudy is the familiar forecast for the Pacific Northwest. The gray days would be harder to live with if the Vit.D levels for me dropped.

    Highly recommended by my doctor

    I usually have no problem swallowing any kind of pills. My Calcium pills are huge, but this pill I have a hard time with. It is because of the shape of the pill with the hard edges, not smooth all the way around. Tends to get caught in the throat easier.

    Good Suppliment & it is really working. No Gelatin

    I had very low D3 so the doc. suggested I take 2000 IU every day. I took it very diligently. The D3 levels are up now in the normal range. This supplement has no Gelatin or other animal products so very good and safe for everyone taking it for good health and D3 deficient people. No side effects. Well worth the investment.

    I will by this product again

    Good price, arrived quickly...will order again. Free shipping is a main consideration of mine. Thank you. Would like to add that although it is vit d3..... It does not say that on the front label. Just says vitd It is listed as d3 cholecalciferol in the ingredients. It took me awhile to see that it was the d3 that I wanted.
