Clinical evidence supports the use of several different supplements for promoting restful sleep. These include:

• Melatonin. This sleep-promoting hormone is naturally released by the body in the hours leading up to bedtime. Melatonin supplementation may help support a healthy sleep-wake cycle especially when you’re trying to realign your natural sleep rhythm due to shift work or jet lag. However, it’s important to use melatonin cautiously as scientists lack information on its long-term effects.
• Magnesium. Magnesium deficiency is increasingly common and may cause nighttime symptoms like leg cramps. Easy for the body to absorb, magnesium glycinate is known for its calming properties and may promote relaxation and sleep. Research indicates that supplementing with magnesium may help some individuals fall asleep faster and stay asleep longer.
• Lavender (Lavandula angustifolia). Essential oil components of English lavender, like linalool and terpineol, support sleep by reducing stress and activity in the central nervous system, lowering blood pressure, and potentially improving mood. Lavender has a long history of use in natural medicine for its calming properties and possesses limited risk for side effects. Lavender oil can be taken by mouth or administered through aromatherapy.
• Valerian (Valeriana officinalis). This root extract contains many bioactive chemicals that can have moderate sedative and relaxing effects on the body. A possible mechanism by which valerian may improve sleep is by increasing the amount of gamma-aminobutyric acid (GABA), a calming neurochemical in the brain.11 Some studies have shown valerian to help people fall asleep faster and sleep more throughout the night.
• L-theanine. An amino acid found in tea leaves, L-theanine is another substance that triggers the release of GABA.12 L-theanine naturally calms anxiety, enhances relaxation, and provides a safe natural sleep aid without drowsiness.13 L-theanine should be used carefully as it can interact with other medications.
