Uses mineral ascorbates, a requirement for high dose C supplementation, is in capsule form (more absorbable), and has 1 gram per pill to reduce the number of pills one has to consume. Clearly superior! I take 2 g. C / day so this is clearly the best choice for me! Next time I am going to buy the larger bottle. Vitamin C (ascorbic acid) is not the active form, whereas mineral ascorbates are the active form. The nonactive form (ascorbic acid) is an acid and the body has to rob calcium from the diet or bones to make a mineral ascorbate before it can be used (which means bone loss). A mineral ascorbate form of C, like Ester C, is the only sensible way to take this vitamin.

I like that I can take one capsule for 1000 mg instead of two 500 mg ones.

I really love this brand of vitamin C but the large sized tablets I have purchased before were too big! I prefer the capsules.

This is a great quality product. Love the C-1000 with bioflavoids. I never get sick.

This really works. Had a bad cold and increased it to 3 per day (had been taking 2 per day) and it decreased the symptoms exponentially.

I had a doctor put me on Vitamin C when I was facing a surgery. I knew it would work. But I really saw it's effect when my father was undergoing Chemo and Radiation which depresses the body's immune system. We all contracted colds and flu that winter and he never did. So when I had my heart surgery, I put myself on Vitamin C and have had no flu or cold problems, even taking care of my grandchildren. Ester C is wonderful because you don't get the burning you sometimes do with other Vitamin C products.

Excellent form of vitamin C - easily absorbed and the 1000mg capsule is much more convenient than taking two 500 mg's.
