Vitamin C: a simple buying guide

Vitamin C supplements in every common format: tablets, capsules, powders, chewables, gummies and oral sprays. The range covers standard ascorbic acid, buffered forms such as calcium ascorbate, liposomal vitamin C, and formulas that add bioflavonoids, rose hips, zinc or collagen.

Vitamin C contributes to the normal function of the immune system and to the reduction of tiredness and fatigue. Vitamin C also contributes to normal collagen formation for the normal function of skin, which is why it often appears alongside collagen. Strengths vary widely, from low-dose chewables to 1000 mg tablets and powders measured by the scoop, so compare the milligrams per serving rather than per tablet. Buffered vitamin C is less acidic than ascorbic acid; powders make it easy to adjust the dose and mix into drinks. Brands include NOW Foods, Doctor's Best, BioTechUSA, OstroVit, Osavi, Nordic Naturals and Cytoplan. See our vitamin C guide for more on forms and doses.
