L-Theanine

L-Theanine Formulas

L-theanine, an amino acid naturally found in tea leaves, is commonly chosen to complement calm focus and everyday relaxation, often alongside caffeine in pre-workout or focus formulas, where the combination is associated with smoother, more sustained energy compared with caffeine alone. Our range is sourced from trusted brands offering clearly stated dosing, with a 1:2 or 1:1 theanine-to-caffeine ratio being a commonly referenced combination in many pre-formulated products, though standalone L-theanine without caffeine is also widely available for evening or caffeine-free use. L-theanine is naturally present in green and black tea, which is part of why tea is traditionally associated with a calmer form of alertness compared with coffee. This category includes both standalone and caffeine-combination formulas.

Food supplements should not replace a varied and balanced diet and a healthy lifestyle.
