Rated 4 out of 5 by from The vitamins were too large and hard to swallow. I like the Ester C except they are so large and hard to swallow. When I bought Ester C before, it came in a capsule which was easier to swallow.

Rated 5 out of 5 by from Ester C A month ago or so,I bought Ester-C at Swanson Vitamins. The purchase was a good one since this is a fine product at a reasonable price. The Ester-C version is better for the body to absorb over a regular Vit C supplement. The Ester-C is the combination of an alcohol + acid.

Rated 5 out of 5 by from Very Good Quality I love this vitamin C because others upset my stomach. This one is easy on my stomach and is very good quality & effectiveness.

Rated 5 out of 5 by from Ester C This product is great value, both health-wise and financially. I love the fact that it contains bioflavonoids to assist with absorption. Many people need this assistance and it gives me satisfaction knowing that I am getting the full benefit of this vital supplement. I do find these tablets a little large to take and end up having to drink a lot of water with them, but I need the extra hydration anyway so it is not enough to prevent me using Ester C 1000mgs.
