Empowering healthier lives since 1968, NOW Foods began when Elwood Richard, a physical chemist, launched Health House, a chain of health food stores in Chicago. Inspired by his research on physical performance through nutrition, Elwood saw the need for affordable natural products. Facing competition from local supermarkets, he founded his own manufacturing company, ensuring cost-effective, high-quality health foods. NOW Foods, still family-owned, has since become a leading brand in the natural product industry, offering an extensive line of affordable, top-quality products. Elwood's vision of accessible health foods continues to drive the company today.
