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.

Thanks for your feedback!

Ester is unique in that it is not excreted from the body for up to 8 hours. Whereas a simple vitamin c is excreted after 3 hours. I personally certainly prefer not in the form of capsules, but powder. there are no unnecessary additives in the form of for example starch .. But it is more convenient for someone to carry around with it, the powder is of course less comfortable to wear. I've been drinking for a couple of years, alternating with another manufacturer. Immunity strongly strengthened much earlier, and the cold in the cold season was a constant phenomenon. Even vitamin C protects against viruses, maintains a good metabolism, parasites are uncomfortable where there is always vitamin C and water.

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

Thanks for your feedback!
