Smart for Life is a small holding company in the nutritional supplements and health products space. Its primary operating business, Doctors Scientific Organica (DSO), develops and sells the Smart for Life brand of meal replacement and weight management products — including nutrition bars, cookies, soups, and shakes — through major retailers like Costco, Walmart, Sam's Club, and Amazon. DSO also sells branded vitamins and supplements. A second nutritional business, GSP Nutrition, focuses on contract manufacturing of vitamins, supplements, tablets, capsules, and powders for third-party brands and retailers. Smart for Life also owns Nexus Offers, a digital affiliate marketing network that connects product vendors with digital marketers on a cost-per-acquisition basis, paying commissions only when marketing efforts result in a sale or lead. Nexus has been refocused to market the company's own nutraceutical products. Smart for Life pursues a buy-and-build strategy, targeting acquisitions of small nutraceutical companies at 4–6x EBITDA, with the goal of building a vertically integrated platform where owned manufacturing at its Riviera Beach, Florida facility reduces production costs and Nexus provides a captive digital marketing channel. Acquisitions are structured with roughly 50% cash and the remainder in stock and seller notes. The company explicitly acknowledges it currently lacks the capital to execute further acquisitions and will need to raise equity or debt to do so. Smart for Life is very small, with roughly 12 employees as of year-end 2023.
