Vitamin C is a staple in many people’s daily health routines, offering a range of benefits from immune support to promoting healthy skin. But with so many vitamin C supplements flooding the market, it can be difficult to know which ones truly deliver the claimed benefits. In this article, we’ll take a look at 15 popular vitamin C supplements, all tested in independent labs to ensure accuracy in their vitamin C content. This way, you can make an informed decision and choose the best product for your needs.
What to Look for in a Quality Vitamin C Supplement
When selecting a vitamin C supplement, several factors come into play, including the actual vitamin C content versus what is claimed on the label. The most important aspect is whether the product delivers the amount of vitamin C it claims to, with products that fail to meet 96% of their label claim being considered unreliable. Apart from that, the form of vitamin C (ascorbic acid, calcium ascorbate, or others), the fillers used, and the capsule type (vegan or not) are also important factors to consider.
The Best Vitamin C Supplements Tested: Our Rankings
15th Place: ProCaps Vitamin C 500mg Complex
ProCaps offers a high-quality vitamin C supplement, but it falls short of meeting its 500mg label claim. Instead, it provides 475mg per capsule, which is 95% of the claim. The product contains no fillers, which is a plus, but it does use gelatin capsules, making it unsuitable for vegans. Available from iHerb for $32.90 for 180 capsules, it costs 38 cents per gram.

GNC’s 1000mg vitamin C supplement delivers 899mg per caplet, which is 89.9% of the label claim. Although it is affordable at $9.99 for 100 caplets (11 cents per gram), it contains several unnecessary fillers, which makes it less desirable from a health-conscious perspective.
