Stress out is a natural, calming tablet/paste, containing tryptophane, hypericum, and taurine. Tryptophane (serotonin precursor) reduces muscle tension and susceptibility to stress. Hypericum increases the amount of serotonin in brain increasing the feeling of happiness. Taurine stops the excessive excitement during stress. Stress Out is not addictive and has no side effects, so it is very safe even with long-term usage."
