Tag: 500 mg vitamin c

For most healthy adults, taking 500 mg of vitamin C daily is generally considered safe, as it falls significantly below the 2,000 mg tolerable upper intake level (UL) established by health authorities. While the recommended daily allowance is lower, many individuals opt for this higher dose to boost antioxidant support and potentially reap other health benefits.

According to the National Institutes of Health, absorption efficiency for vitamin C drops to less than 50% when oral doses exceed 1 gram per day. This raises a key question: how does the body absorb 500 mg of vitamin C, and is a single high dose effective?

The Recommended Dietary Allowance (RDA) for adult men is 90 mg of vitamin C per day, with adult women needing 75 mg. But with many supplements offering higher amounts, a common question arises: should you take 500 mg of vitamin C every day?

The National Institutes of Health sets the Recommended Dietary Allowance (RDA) for adult men at 90 mg and for women at 75 mg, making 500 mg a significantly higher intake. Understanding whether 500 mg is a lot of vitamin C involves comparing this dose to both these baseline needs and the safe upper limits for intake.
