Rexall Sundown

Rexall Sundown is a prominent developer and manufacturer of vitamins, minerals, and dietary supplements. Originally founded in 1976 by Carl DeSantis, the company became a leader in the consumer healthcare space with brands like Sundown Naturals and Osteo Bi-Flex. The company focuses on providing accessible nutritional products to the mass market through major retail channels. In 2000, it was acquired by Royal Numico for approximately $1.8 billion, marking one of the largest deals in the supplement industry at the time. Following subsequent ownership by NBTY (The Nature's Bounty Co.), the core brands were eventually acquired by Nestlé Health Science in 2021. The company's legacy continues through its widely recognized product lines that target general wellness, bone health, and immune support.
