This followed a study of urinary excretion of vitamin C (AA) that demonstrated 500 mg twice a day provides levels sufficient to cause continuous urinary excretion in humans.

How does vitamin C work as an antioxidant?

As an antioxidant, vitamin C provides protection against oxidative stress-induced cellular damage by scavenging of reactive oxygen species, vitamin E-dependent neutralization of lipid hydroperoxyl radicals, and by protecting proteins from alkylation by electrophilic lipid peroxidation products.

Is it safe to take 500mg of vitamin C daily?

Advertisement. For adults, the recommended daily amount for vitamin C is 65 to 90 milligrams (mg) a day, and the upper limit is 2,000 mg a day. Although too much dietary vitamin C is unlikely to be harmful, megadoses of vitamin C supplements might cause: Diarrhea.

What kills free radicals in the body?

Antioxidants are chemicals that interact with and neutralize free radicals, thus preventing them from causing damage. Antioxidants are also known as “free radical scavengers.” The body makes some of the antioxidants that it uses to neutralize free radicals. These antioxidants are called endogenous antioxidants.

Which form of vitamin C is best?

Ascorbic acid: Also called L-ascorbic and L-ascorbate, ascorbic acid is vitamin C in its purest form. It’s the most bioavailable form, meaning it is readily absorbed by the body through the bloodstream. Sodium ascorbate: Pure ascorbic acid can be too acidic for some people’s stomach (and cause heartburn).

What is antioxidant C good for?

It is involved in the first line of antioxidant defense, protecting lipid membranes, and proteins from oxidative damage. As a water soluble molecule, vitamin C can work both inside and outside the cells, and can neutralize free radicals and prevent free radical damage.

Is vitamin D an antioxidant?
