Swanson Sleep Formula goes beyond melatonin alone by combining four complementary sleep-support ingredients in a single formula: melatonin to support a healthy sleep-wake cycle, Suntheanine® L-theanine to promote relaxation, Relora® to help manage occasional stress, and ZMA® (zinc, magnesium, and vitamin B6) to support overnight recovery and relaxation. This multi-targeted approach is designed to support both falling asleep and achieving more restful sleep, making it a comprehensive alternative to single-ingredient sleep supplements.
