L-Theanine is an amino acid from green tea that supports a calm, alert state, which is why it fits people who want steadiness rather than more stimulation during a daily stimulant routine. It supports the calming side of attention without causing drowsiness, so focus can feel smoother rather than sharper-then-flatter.
For anyone already on a stimulant, more alertness is rarely the missing piece. Evenness is. That is the space L-Theanine works in.
L-Theanine supports the production of calming neurotransmitters, including serotonin, dopamine, and GABA, which together help balance mood and take the edge off the jittery feeling that can come with stimulant use. It is associated with alpha brain wave activity, which researchers have linked to a relaxed, focused state, though this is still an area of developing evidence and individual response varies (PMID 33751906). Controlled research on four weeks of L-Theanine has also looked at self-reported stress and cognitive measures in healthy adults* (PMID 31623400). The takeaway is calm-with-focus, not sedation.
Stimulants deliver focus by raising dopamine and norepinephrine, and that can tip into a wired, on-edge feeling. L-Theanine supports a calmer response alongside that, so the day can feel steadier without dulling the attention you rely on*. It is support for evenness, not another lever for intensity.
Stasis Daytime includes L-Theanine at 200mg, sitting alongside Shoden Ashwagandha and saffron for the calmer-response side of the day. It also appears in Stasis Nighttime for evening calm. Every dose is listed on the ingredients page.
In an open-label consumer survey, 96% reported experiencing less brain fog.†
Does L-Theanine make you calm or focused? Both, in a sense. It supports a calm yet alert state, which many people experience as steadier focus rather than either sedation or a spike.
Will L-Theanine make me drowsy during the day? It is associated with calm without drowsiness, which is why it suits daytime use alongside a stimulant.
How much L-Theanine is in Stasis Daytime? 200mg, always listed individually on the label.
Can I take L-Theanine with my stimulant? Many people do, but always consult your healthcare provider before adding a supplement to a routine that includes a stimulant.
