Tag: L theanine timeline

According to research published by the National Institutes of Health, peak plasma concentrations of L-theanine occur roughly 32 to 50 minutes after oral administration. This provides a strong starting point for understanding how quickly this calming amino acid can begin to work, though the full experience is more nuanced.

Within 30 to 60 minutes of consumption, most users begin to feel the relaxing effects of L-theanine. Knowing how long does it take to see results with L-theanine, however, depends on whether you are looking for immediate relief from stress or gradual improvements in sleep and cognitive function.
