This oregano extract is made using the correct species of non-GMO oregano to provide the best-studied polyphenol, Carvacrol, along with a broad spectrum of other polyphenols and related oregano constituents. As a natural food-based supplement, it is safe to take every day. Twist open the capsule to use the powder as an extra-potent culinary spice, or take one capsule per day as a convenient way to use the standard dose. This is stronger than ordinary kitchen herbs, so start with one capsule and increase gradually to the desired dosage.
