"L-theanine may help with restless legs syndrome (RLS) because it can increase GABA levels in the brain. GABA is a chemical that can help calm the brain.
How it works
L-theanine can be taken as a supplement or in tea.
It's recommended to take it in the evening before bed.
L-theanine can be taken with melatonin, but you should check with your doctor before taking it with prescription medications.
Other treatments for RLS
Magnesium oxide and vitamin B6 supplements may help improve sleep quality and RLS symptoms.
Iron supplements may help because the body needs iron to make dopamine, which helps control movement.
Massaging your legs
Taking a hot bath in the evening
Applying a hot compress to your leg muscles
When to seek help
If you're experiencing more serious sleep issues like insomnia or sleep apnea, L-theanine likely won't help.
Supplement safety
When choosing a supplement, look for independently tested products and consult a healthcare provider. "
