Difference between ester C and vitamin C?

[Guest guest]

My husband bought me some Vitamin C 500 mg.( under the impression that the

Vitamin C was the same as the ester C but far less expensive ) I had tried the

ester C before on Dr. Nase's recommendation and I don't remember having any

bluhing/flushing problems . I am wondering it there is a difference between the

2, especially if there is something in the vitamin C which can induce

blushing/flushing. I think that I did read that the ester C was more gentle to

the stomach.
