Ascorbic acid is the purest form of vitamin C, and this form is the sodium salt of ascorbic acid.
Form: Vitamin C can appear on the ingredient label as several different names, but the one you want is L-ascorbic acid, which is the most effective. An older study comparing common vitamin C derivatives with L-ascorbic acid didn't show an increase in absorption.
Fruits and vegetables are the best sources of vitamin C. Citrus fruits, tomatoes and tomato juice, and potatoes are major contributors of vitamin C to the American diet. Other good food sources include red and green peppers, kiwifruit, broccoli, strawberries, Brussels sprouts, and cantaloupe.

To your mixture of vitamin C and starch indicator, add drops of iodine, carefully counting the drops, until the solution develops a blue-black colour that does not disappear on stirring.
You can test the authenticity of the supplements by mixing a spoon of it in water. If it's fake, the product will leave behind some powder or residue in the glass, while an original product won't. Fake supplements also have a pungent smell and a bad aftertaste.
Ascorbic acid: Also called L-ascorbic and L-ascorbate, ascorbic acid is vitamin C in its purest form. It's the most bioavailable form, meaning it is readily absorbed by the body through the bloodstream.
For adults, the recommended daily amount for vitamin C is 65 to 90 milligrams (mg) a day, and the upper limit is 2,000 mg a day. Although too much dietary vitamin C is unlikely to be harmful, megadoses of vitamin C supplements might cause: Diarrhea. Nausea.
