Naringin is mainly found in grapefruits. The grapefruit is a large, dimpled, round citrus fruit. It is likely to be a cross between a pomelo or shaddock (Citrus grandis, a large Malaysian citrus) and a sweet orange. Grapefruit seed extract is processed from grapefruit seeds and pulp obtained as a by product from grapefruit juice production. Vegetable glycerin is added to the final product to reduce acidity and bitterness.
