9.5-HTP
It’s short for 5-hydroxytryptophan, a compound that your body makes from foods. Your body uses 5-HTP to make melatonin, an important hormone for sleep. Some studies suggest, but don’t prove, that 5-HTP supplements made from plant seeds may help you log more sleep. Experts recommend 100-300 milligrams of 5-HTP before bedtime. Side effects include nausea and headaches.
