L-Theanine in depth
What it is
L-theanine is an amino acid found almost only in the tea plant (Camellia sinensis) and in a small number of mushrooms. It is not one of the amino acids used to build human proteins.
Forms you may see on a label
Labels show “L-theanine”, supplied as a powder or in capsules. Supplement L-theanine may be extracted from tea leaves or made in a laboratory. Both give the same molecule.
Where it occurs naturally
Green, black and white tea all contain L-theanine, with amounts that vary by tea type, growing conditions and how the tea is brewed. A cup of tea also contains caffeine, whereas L-theanine supplements do not.
Safety notes and who should check first
L-theanine is generally well tolerated at typical supplement amounts in the studies that have been published. Check with a doctor before use if you are pregnant or breastfeeding, or if you take medicine that lowers blood pressure or causes drowsiness.
