The quality and price are right-- that draws us to Sam's every time we need more D3. According to research, D3 deficiency is associated consistently with risk of disease and illness. To the credit of Sam's Club marketing, the D3 product now uses a light-resistant dark bottle to reduce the amount of UV entering the bottle, damaging D3 molecules.

My doctor said my blood test revealed I was low in vitamin D. Not anymore after taking this product daily! Vitamin D is so important for our health in preventing cancer and building immunity.

Best vitamin D supplements I’ve taken. I’ve been taking this brand from Sam’s for years. On occasion I have tried a couple other brands, but ALWAYS come back to these. I’m not going to bother with any others again.

Glad to be able to purchase this item on line. Sure would be great to obtain all supplements on line since many others are not available in the local Sam’s Club!!!

no problem with product ! problem was packaging. no paper or plastic air pillows so the product wont roll or rattle around in the box. nothing was damaged but it may have if it were an other product.

Why bother trying to make these gluten and allergen free if you’re going to have Soybean oil as a top ingredient right after the actual vitamin D3? The majority of brands/companies use Soybean oils to make a cheaper product, but that leaves myself and many others unable to take them due to having allergies to Soybeans. I wish more companies would take this into consideration and start making quality products that everyone can take.

Been using for years and like it very much

Great price for huge amount.

Actual bottle states "PRODUCT OF CHINA AND USA". No idea where these vitamins are actually from.

My husband and I have used these for years. We are very happy with them.
