    What are Tannins?

    Tannins are water soluble, polyphenolic compounds. They are categorized as either hydrolyzable or condensed. Tannins have astringent and antioxidant properties and are renowned as GI health protectants. Tannins give the bitter taste to black teas and are a significant component of Redwood Tree bark, giving it its distinct red color.

    Are Tannins taken in a dietary supplement safe?

    Yes. Viracin contains condensed plant tannins. These condensed tannins have antioxidant activity properties and, as they are not absorbed by the body, will support GI health and healing. Tannins taken as a dietary supplement, drunk as teas or in wine, eaten in fruits or food have been shown to exhibit significant antioxidant activity.

    Viracin is non-toxic and can safely be taken by a variety of individuals.

    We suggest using a probiotic and multivitamin to support beneficial bacteria growth and healthy mineral balance.

    Occasionally individuals may experience temporary constipation after taking Viracin for a long period of time. To avoid temporary constipation, increase water intake while taking Viracin and consider taking a Magnesium supplement (see our MagC Vitamin C Antixoidant and Magnesium Formula).
