L-Theanine dosage: what the research used
Short answer. Published work on L-Theanine and attention sits around 200 mg taken once daily. 30BASE uses exactly 200 mg.
L-Theanine is an amino acid found in green tea. It is one of the few compounds in this category with a consistent studied amount, which makes it a useful reference point when learning to read a supplement panel.
The studied dose
Most published work on attention and the relaxed-but-alert state sits around 200 mg as a single daily amount. Nobre and colleagues (Asia Pacific Journal of Clinical Nutrition, 2008) is the commonly cited reference. Smaller amounts appear on plenty of labels, usually where the total serving is only one or two capsules.
What it supports
L-Theanine supports calm concentration: a relaxed but awake state rather than a sedated one. Paired with caffeine it is the compound most often credited with softening the edge of coffee, which is why the two are so frequently studied together (Owen and Haskell, 2008). It is also one of the few compounds here where people commonly notice something in the first hours rather than after weeks.
What it does not do
It is not a sedative and does not cause drowsiness at this amount. It is not a treatment for any condition. It does not make thinking faster. The honest description is that the background gets quieter, which makes holding attention easier.
How 30BASE uses it
30BASE Daily Cognitive Stack contains L-Theanine 200 mg, the studied amount, alongside L-Taurine 800 mg. It sits in one pre-portioned daily sachet with six other compounds, eight capsules taken after breakfast, printed in milligrams on the label with no proprietary blend, and third-party tested in every production lot.
