New Mood by Onnit combines 5-HTP, GABA, L-theanine, and other calming nutrients to support healthy serotonin levels, ease everyday stress, and promote a relaxed transition into sleep. A good option for winding down after a stressful day, not just for sleep itself. A larger 60-capsule bottle for extended use. Take as directed on the label, in the evening. Avoid combining with SSRIs or other serotonin-affecting medications without talking to your doctor first.
