Author(s): Lanny L. Johnson

Protocatechuic acid (PCA), is a natural phytochemical found throughout nature: in soil, plants, vegetables, streams, ponds and lakes. PCA is common to the human diet and is also produced in small amounts by bacteria in the human large intestine. PCA is non-toxic, non- allergenic and nonmutagenic and the side effects are minimal. It is generally recognized as safe by the FDA as a food flavoring additive (G.R.A.S.).
