L-theanine is one of the best-known and most extraordinary active ingredients in tea. It is being studied extensively for its potential role in several of tea’s key effects (green tea in particular): restoring calm and relaxation, mental clarity, memory, concentration, etc.
Natural, high-strength and particularly effective, our L-Theanine supplement is part of our Stress & Mood category.
It is not to be confused with theine, which refers to the caffeine found in tea.
Green tea has a number of recognised health benefits, some of which scientists attribute to its L-theanine content. These include, in particular:
SuperSmart’s L-Theanine supplement is notable in 2 important respects:
It’s first worth restating that tea is a fragrant drink that originated in China more than 2500 years BCE. It is made by steeping Camellia sinensis leaves in hot water.
More specifically, green tea is processed in such a way as to prevent oxidation of the leaves (unlike black and oolong tea), which gives it its green colour and distinct flavour. This processing also preserves its high content of L-theanine and antioxidant compounds.
L-theanine is primarily found in green or white tea, though smaller amounts are also present in:
L-theanine is generally considered to be safe for most people.
However, a high intake, via a dietary supplement, may:
If you’re finding life quite stressful at the moment, you might want to consider taking magnesium alongside your L-theanine supplement. This mineral is essential for your nervous system and muscle relaxation (try, for example, the 8 synergistic forms of magnesium combined in the supplement OptiMag).
GABA is an inhibitory neurotransmitter naturally present in the body, which promotes relaxation and sleep. In addition to supplementing with L-theanine, which is thought to have an effect on GABA levels, you could also supplement with GABA directly, ideally a liposomal form for maximum bioavailability (try Liposomal GABA).
If you’re also taking theanine for its effects on mental performance, then consider taking a ‘ nootropic’ supplement too (such as Noopept, scientifically shown to stimulate cognition).
