Valerian extract works rapidly, often in less than an hour, when taken in doses of a few hundred milligrams, and can be taken up to three or four times per day.
5-HTP (5-hydroxytryptophan): Shown by clinical research to treat depression effectively. 5-HTP, an amino acid, allows your body to increase levels of serotonin, a mood-related neurotransmitter in the brain. Low serotonin levels have been linked to depression, and many prescription antidepressants work by increasing serotonin activity. For most people, taking 50-300mg of 5-HTP per day helps improve mood in just a few weeks without causing side effects that antidepressants can.
