An L-theanine supplement from green tea
L-theanine is an amino acid naturally present in green tea leaves (Camellia sinensis). Théanine activ’ from NATURAMedicatrix uses a purified green tea leaf extract, standardised to 40% L-theanine: 250 mg of extract provides 100 mg of L-theanine per capsule.
The formula is enriched with vitamin B8 (biotin), which contributes to normal functioning of the nervous system and to normal psychological function.

Negligible caffeine and EGCG content
The green tea extract in Théanine activ’ is purified to the point where its caffeine (theine) and EGCG (epigallocatechin-3-gallate) contents are negligible: 1.25 mg of caffeine per capsule, i.e. 5 mg per 4 capsules, and less than 1.25 mg of EGCG per capsule.
Compared with a cup of green tea, one capsule of Théanine activ’ contains 40 times less theine and 10 times more L-theanine.
Theanine and theine: two different compounds
Despite their similar names, L-theanine, an amino acid, has nothing to do with theine, which is simply the caffeine in tea. Théanine activ’ provides the former and keeps the latter to a minimum.
