Zenbev versus Sleep Medications

Virtually every sleep medication, either herbal or pharmaceutical, disrupts sleep architecture. Medications currently available tend to increase light sleep (stages 1 and 2) at the expense of deep sleep (stages 3 and 4) as well as inhibiting REM sleep which results in side effects of drowsiness and lack of refreshment. As the tryptophan in Zenbev allows the brain to produce melatonin, none of the sleep stages are compromised, resulting in a preservation of sleep architecture and a deep, uninterrupted sleep.
