Excellent product as usual from the NOW brand. I have a hard time swallowing some of the larger pills, but I find the capsule version to be no problem at all. So glad to find all the NOW products at

I am very happy with the NOW Foods brand. They are known for good quality vitamins.

The difference in price buying this product from as opposed to my local vitamin store was incredible. I saved over $10.

Note: if you have trouble swallowing big pills, then you might find these a little large.
