Butyrate is an essential end product of a healthy microbiome. Primarily, it fuels your gut cells, strengthening the gut lining. Butyrate naturally occurs with a distinctive, fermented scent. (Ok, we’re trying to make it sound nice, but it can be a little smelly.) Some people are more sensitive to this scent than others, but the odor means it's premium quality and ready to work. BodyBio Butyrate is free of wheat, gluten, yeast, corn, soy, dairy, artificial colors, and resins.
