alli Capsules will return to retailers' shelves in June. GSK, the manufacturer of alli, has been experiencing a supply shortage of the active ingredient used in alli. We apologize for any inconvenience this supply shortage is causing our consumers. We are excited to get alli product back on shelf for the many consumers who rely upon the brand to help them achieve their weight loss goals. Until alli is once again available, consumers should continue to adhere to the recommended diet and physical activity routine, which are the cornerstone of any weight loss program, and continue using alli once it is available.
