Carnosic acid 40% is a natural antioxidant manufactured in Canada with Radient’s proprietary technology for the extraction and purification of carnosic acid from rosemary leaves using ethanol and water.

Extracts of rosemary (Rosmarinus officinalis) are widely used as a natural food preservative to protect various food products from rancidity. They have been popularized in the food industry due to the growing consumer demand for “all-natural” foods. Carnosic Acid 40% is produced using a patented gentle extraction process that selectively extracts carnosic acid, the most potent antioxidant found naturally in rosemary leaves and minimizes the formation of other less effective oxidative degradation products. Carnosic acid 40% is all natural, has minimal flavor and color and is produced using only ethanol and water as the extraction solvents.
