Taurine activates GABA(A) receptors in the region of the brain known to regulate sleep, and is involved in the production of melatonin which is a “sleep hormone”. It acts as a neural sedative to calm anxiety and reduce stress, which is a very common factor that induces insomnia. Taurine supplementation has been shown to improve sleep by 50%, changing from diurnal to nocturnal. Experts recommend taking 1000-2000mg of taurine per day before bedtime for a calm and stress-free sleep.
