As an antioxidant, vitamin C scavenges free radicals in the body and protects tissues from oxidative stress.1-8 Vitamin C also promotes the absorption of iron, while inhibiting its oxidation.

More vitamin C is contained in the adrenal glands than any other organ in the body and is required at higher levels during times of stress. Physical stresses on the body such as ingestion of heavy metals, cigarette smoking, and extreme temperatures, also signal the need for increased intake of vitamin C.
