Vitamin C absorption and metabolism

Absorption of vitamin C occurs in the intestine. The amount absorbed depends on the dose as the absorption mechanism is saturable and any excess excreted in the urine in two to three hours. As vitamin C is water soluble, only a small amount (about 4 to 5 g) is stored in the body. Vitamin C levels in the body are regulated by absorption and kidney excretion mechanisms.
