Tranquil PM + GABA is a carefully designed formula made for patients suffering from occasional insomnia or sleeplessness. Tranquil PM + GABA promotes a healthy sleep cycle by naturally boosting levels of serotonin1 and GABA, the neurotransmitters responsible for sleep-regulation and relaxation, plus melatonin. This formula includes 5-HTP, PharmaGABA®, and taurine, which help increase levels of the neurotransmitters and hormones that supports relaxation2 prior to bedtime and promotes the deep, restorative stages of sleep3. **
