NutriBiotic has been a trusted source for high-purity GSE (Grapefruit Seed Extract) and immune support products since 1980. Their GSE liquid concentrate and capsules are among the most concentrated and consistently potent grapefruit seed extracts on the market, used by natural health practitioners for antimicrobial support, food safety, and immune function. Beyond GSE, NutriBiotic offers a complete line of vegan protein powders, rice protein, skin care, and oral care products made from pure, simple ingredients. Their products are non-GMO, free from synthetic additives, and manufactured with rigorous quality standards. NutriBiotic's oral care line — particularly their Dental Gel and Mouthwash — provides effective antimicrobial protection using GSE as the active ingredient instead of harsh chemicals.
