Westend61 / Getty Images Sleep is essential for health. According to one estimate, roughly 56% of people in the United States experience sleep issues, such as difficulty falling asleep or decreased sleep duration.1 Poor sleep is linked to an increased risk of health conditions like heart disease and obesity. Sleep deprivation contributes to dangerous accidents and impacts the ability to participate fully in work and social life.
Despite its known benefits, many struggle to get the recommended nightly sleep of seven to nine hours. Many sleep supplements exist, but not all may be effective or safe. Many people have tried L-theanine for sleep. L-theanine influences neurotransmitters that encourage relaxation and sleepiness.

Preliminary studies in mice show that a combined supplement of L-theanine and magnesium increases sleep duration and reduces sleep disturbances.1 Still, more research in humans is needed.
It is also vital that you discuss any sleep concerns with your healthcare provider to rule out issues such as sleep apnea, chronic insomnia from depression or anxiety, mineral deficiencies (e.g., iron), and more.
Supplement use should be individualized and vetted by a healthcare professional, such as a pharmacist, healthcare provider, or an RD or RDN . No supplement is intended to treat, cure, or prevent disease. L-Theanine’s Sleep Benefits
