First of all these are little and so easy to take. I typically take 2 a day in the summer and take 3 a day in the winter. I feel like they help.

Doc suggested I take 5000 i.u. for my particular situation, but I had a hard time finding 5000 - could only find less to much less. Then here’s MM at my local Sam’s with 5000 i.u. right there on the shelf. Thanks Sam’s!

This product doesn’t have any quality for Vitamin , so I had returned. Don’t purchase this product Because it’s doesn’t follow the USA food standards. And this product isn’t American product.

Best priced in my research. I bought the 5000 units instead of 2000 as they were the same price so I take them every other day now instead of every day.

Started taking this vitamin several months back. My levels went up but this is a synthetic made vitamin. Anything that says DL in front of the ingredient means that it is synthetically made. It's best to take the natural form. My doctor has suggested there are other vitamins that are better on the market for me. I've stopped taking this. When I started taking another product my levels drastically increased. I also felt so much better. I have many MAJOR medical conditions in which I felt a dramatic difference!

Very good quality vitamin

Good way to get my Vitamin D3

Vit D keeps our levels up . Easy to swallow and great price .

Great value for a needed staple

Good product at a good price.
