What is the pH of this product? – The Original GSE Liquid Concentrate has a pH of about 2.75 and the Maximum GSE Liquid Concentrate has a pH of about 2.2, which are both very acidic. This is why we recommend you dilute Grapefruit Seed Extract before use.


What about the “grapefruit juice effect”? – There is an effect of grapefruit juice known as the “grapefruit juice effect”. Two components found in grapefruit juice, naringin and naringenin†, inhibit production of an enzyme, thus increasing the rate of absorption for certain classes of drugs. You may want to check with your physician or pharmacist to see if there is any interaction between your medication and the naringin and naringenin*.


*The Original GSE Liquid Concentrate contains only.1% and the Maximum GSE Liquid Concentrate contains only 0.3% of these compounds.
