Relaxation PM Blend is a synergistic amino-acid and neurohormonal formula studied for its effects on promoting relaxation, aiding sleep onset, and supporting nighttime recovery. This blend combines the inhibitory neurotransmitter GABA with melatonin, arginine, and glutamine to modulate key pathways involved in sleep-wake cycles, neuronal calmness, and muscle recovery. In research settings, these compounds work together to influence circadian signaling, nitric oxide production, and neurotransmitter balance—all of which may contribute to improved sleep quality and restorative recovery. Relax PM Blend is ideal for studies focused on sleep regulation, stress modulation, and nighttime muscle support.
