NutriBiotic Maximum GSE steps up the concentration of the brand's classic grapefruit seed extract, blending Citricidal grapefruit seed extract (60%) with vegetable glycerine (40%) in an unfiltered, full-bioflavonoid concentrate.
Because of its strength, the label calls for diluting even a single drop in at least one fluid ounce of water before use.
This 1 fl oz bottle is vegan, gluten-free, and made without GMOs or common allergens, continuing a grapefruit seed extract tradition the brand has offered since 1987.
