Lysulin

Lysulin is a private U.S. consumer health company focused on nutritional supplements for blood sugar support, A1c management, and insulin function. Founded by Dexcom founder John Burd, the company markets commercially available products formulated with lysine, zinc, and vitamin C for people with diabetes, prediabetes, or elevated blood sugar concerns. Its portfolio includes capsules, powder, liquid, chewables, and a weight-loss shake, and it also sells home A1c testing kits through its direct-to-consumer channel. Lysulin appears to operate as a commercial supplement brand rather than a drug-development biotech, with no disclosed clinical-stage therapeutic pipeline typical of pharma or biotech companies.
