Vitamin C tablets usually contain either sodium ascorbate or potassium ascorbate along with other things such as flavouring and glucose (or an artificial sweetener) and sometimes sodium bicarbonate to make them effervescent. Vitamin C is ascorbic acid and may be present in effervescent tablets when it will react with the sodium bicarbonate in contact with water to produce carbon dioxide and the salt, sodium ascorbate.

The ingredients are generally stated on the packaging of the tablets, so always check the packaging to see if the contents are suitable for your needs.
