Can't tell the difference yet

The tab is big and hard to swallow. But I don't see the result yet.

I highly, highly recommend this product. I've taken mega-doses of vitamin c for decades, and have incorporated this into my arsenal for several years. These are relatively small tablets, and the tablets are manufactured in such a way that they break down quickly and easily. For this reason, and because they are non-acidic, they can be taken on an empty stomach if desired. They absorb well and never cause digestive upset. I give this particular Ester-C huge credit for my excellent health. I believe that nutritional supplements saved my life. I've tried a lot of products, and I know what works and what doesn't. My reviews are honest, straighforward, and based on my experience. Read my other reviews to quickly learn from my three decades of research and experimentation.

May be an ok product

I got it following a recommendation for being a more efficient type of Vitamin C with higher bioavailability and longer half life, but as with other Vitamin C products, I couldn't feel its benefits during the cold season

Excellent vitamin C w/bioflavinoids

American Health makes the best Ester C 500 with bioflavinoids. Usually get the 225 quantity, but I needed a smaller bottle to fit into my storage box.
