The human body cannot synthesize vitamin C on its own, so it must be obtained from external sources such as fruits, vegetables, and vitamin C supplements.
Vitamin C (Ascorbic Acid) supplements are available in a wide variety of forms, including effervescent tablets, chewable tablets, sustained-release tablets, capsules, and gummies.
