Re: Ester C
Ester-C is a non-acidic form of Vitamin C. I have been taking it for quite a number of years. Some sources claim that Ester-C contains metabolites that may enhance the delivery of essential Vitamin C to the cells of the body, resulting in higher blood levels. On the other hand, there are some who dispute this claim. My guess is that it's at least as good as any other form of Vitamin C, and since it is non-acidic, high doses will be much better tolerated. Of course, it is also about twice as expensive as ordinary Vitamin C.
