Should you be taking a vitamin C supplement? Which are the best vitamin C supplements in terms of quality and value?

Vitamin C is an antioxidant critical for maintaining healthy connective tissue. Research shows that getting too little can be a problem, but so can getting too much. Unfortunately, our tests of vitamin C supplements found that more than 25% of the products selected for review didn't contain the amounts of vitamin C listed on their labels. Two high-dose products contained about 40% more vitamin C than listed -- which could cause side-effects for some people -- and one had 15% less than listed.

We also found that a common dose of vitamin C from a high-quality supplement can cost as little as 1 cent, or you can spend over a dollar.

In this comprehensive report about vitamin C
supplements, you'll get test results and quality ratings for 25 vitamin C products (including 14 that passed our Quality Certification Program) and information about one other vitamin C supplement similar to one that passed testing. You'll learn:
    • Which vitamin C supplements passed testing, and which failed
    • Which high-quality vitamin C supplements are also lowest cost
    • What vitamin C can and cannot do for your health
    • The potential advantages of forms of vitamin C, such as Ester-C, sodium ascorbate, and slow-release vitamin C
    • The value of additional ingredients, such as bioflavonoids (e.g., quercetin, dihydroquercetin, rutin, and hesperidin), often found in vitamin C supplements
    • The vitamin C dosage to help prevent or treat conditions such as colds, gout, and vitamin C deficiency 
    • The potential side-effects of vitamin C and other concerns, including the potential for kidney stones and interactions with drugs and diagnostic tests
