Abich Labratories performed independent challenge testing on our Professional Strength Grapefruit Seed Extract. Refer to the Documents section of this page to find a link to the Challenge Test Results.

Professional Strength Grapefruit Seed Extract is formulated from both the seeds and the pulp of grapefruits (Citrus grandis). The process of extraction yields an active botanically-derived product consisting of flavonoids, such as naringen, ascorbic acid, tocopherols and citric acid which is then blended with USP vegetable glycerin and additional ascorbic acid. The main active constituents are flavonoids and ascorbic acid. The heavy viscous liquid is yellow/golden brown in color and has a mild citrus aroma.
