NutriBiotic® GSE Liquid Concentrate is a compound derived from the seed and pulp of grapefruit. This formula is used by healthcare professionals worldwide.
The 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 always recommend grapefruit seed extract liquids be diluted according to the directions before use.
