This is the vitamin C that I take every day. Capsules are on the large side but they go down easily. Not hard on the tummy. I believe they are partly why I have not had a cold in the past years.

I have been taking this product for years and was so happy to see it at Thrive! Not a hard pill, but a capsule that is gentle on the digestive system.

The best Vitamin C!

Posted   by Shannon
Ester C is the best form of vitamin C one can take being more bioavailable than the regular form. And, if you are prone to heartburn, this formula is buffered and doesn't upset the stomach. I cannot recommend it enough.
