L-Theanine is a non-protein amino acid of natural origin, present in the leaves of Camellia Sinensis, the plant from which the different varieties of tea are obtained: green, black, white and oolong.
Unlike other essential amino acids, L-Theanine does not participate in protein synthesis, but acts directly on the central nervous system, modulating brain activity and promoting a state of conscious relaxation.
L-Theanine can help:
- Improve concentration and focus.
- Increase cognitive performance.
- Promote relaxation and sleep quality.
- Modulate the physiological impact of stress, both mental and physical.
- Post-training muscle recovery.
- Inhibit the action of free radicals.
