Any water based liquid vitamin that includes Ascorbic Acid is bunk, in the presence of copper or other catalysts it will break down to dehydroascorbic by up to 35% in about 15 min. After that it is further decomposed to oxalic acid and threonic acid, neither of which you want in your body. If you could stop it at the dehydro stage, no problem, but you can't. Forget about liquid vitamins and buy high quality caps/tabs from manufacturers with very short shelf life policies, like LEF, Jarrow, maybe AOR(haven't looked).
