Gone in 6 Hours
Posted by Reviewer1183204 on May 12, 2008
Studies show no matter how much Vitamin C you take, what you take is gone from your body within 6 hours. Ester C or Calcium Ascorbate is uffered C and is easier on your stomach. Since I take large doses this is perfect. The price was excellent also.

American Health Ester C
Posted by Reviewer1583487 on Dec 30, 2008
Ester C is an excellent source of vitamin C which is gentle on the digestive system. I think it is easily absorbed and this formula remains "active in the immune system for up to 24 hours." A good protection for the winter months.

The best form of supplement Vitamin C, so far as I'm aware. This one comes in easy-to-swallow tablets. Terrific!

clearly felt the rush of vigor after eating, I tracked the purpose! Highly recommend during the fall, spring and winter as a cold prevention
