Clinical trials have been conducted to investigate aspects of the nutritional value of erythorbic acid. One such trial investigated the effects of erythorbic acid on vitamin C metabolism in young women; no effect on vitamin C uptake or clearance from the body was found. A later study found that erythorbic acid is a potent enhancer of nonheme-iron absorption
Absorption (Pharmacokinetics)

In pharmacology , absorption is the movement of a drug into the bloodstream.Absorption involves several phases. First, the drug needs to be administered via some route of administration and in a specific dosage form such as a tablet, capsule, and so on....
