The Truth About Grapefruit Seed Extract



rapefruit seed extract. Sounds so friendly, doesn´t it? You´ve heard it touted as a “natural” preservative, and the health food store sells it in a capsule as an antifungal supplement. If everybody says that it´s natural they must be correct, right? Wrong.

Grapefruit seed extract is not grapefruit juice. It is also not grapefruit essential oil and it is most certainly not an herbal tincture. Chemical manufacturers take the leftover grapefruit pulp, a waste by-product from grapefruit juice production, and in an intensive, multi-step industrial chemical process, change the natural phenolic compounds into synthetic quaternary ammonium compounds. Typically, in chemical synthesis of this type, chemical reagents and catalysts are used under extreme high heat and pressure or vacuum. Synthetic ammonium chloride is one of the chemical catalysts used in this process.
