I would like to know as well. I mean, typically vitamin C products, at least the good ones, are expensive because it's a highly unstable antioxidant. And for $40, that's rather inexpensive. So yeah, does anyone know at all? I've searched all over the web and I can't seem to find the answer. If all else fails, I'll have to contact the company directly.
