L-Theanine 200 mg

Greatlife L-Theanine contains a high-quality L-theanine ingredient derived from green tea and standardised to 98% L-theanine. The ingredient has been carefully selected with a strong focus on purity, quality and a consistent L-theanine content. L-Theanine is a well-studied amino acid that occurs naturally in tea and is particularly of interest for relaxation, mental sharpness and the ability to maintain calm focus without causing drowsiness. This supplement is pure and free from unnecessary additives and GMOs.

For best results, we recommend taking L-Theanine approximately 30–60 minutes before bedtime when the aim is to support relaxation and sleep quality. It can also be taken during the day when calm focus is needed or during periods of high mental demand. The product can be used daily and is suitable both for occasional use and as part of a long-term routine.

From a biological perspective, L-Theanine has been studied for its effects on signalling within the nervous system, including its relationship with GABA, glutamate and dopamine. Studies have also found an association between L-Theanine and increased alpha brain-wave activity, which is linked to a state of relaxed alertness. This makes L-Theanine particularly interesting when the aim is to combine mental clarity with a calmer state of mind.

Why L-Theanine?

L-Theanine has several interesting properties compared with many other ingredients used for relaxation and mental focus:

Support for relaxation and mental clarity

  • L-Theanine may help promote a calm state without normally causing drowsiness.
  • It is particularly of interest for calm focus and mental concentration.

During periods of stress

  • L-Theanine has been studied in relation to perceived stress and relaxation.
  • It may be a useful supplement during periods of high mental demand or when it is difficult to unwind.

For evening use and sleep

  • L-Theanine is often taken in the evening because it may promote relaxation without acting like a traditional sleep aid.
  • It may therefore be particularly suitable for people who find it difficult to wind down before bedtime.

L-Theanine from green tea with 98% purity

Greatlife uses a carefully selected L-theanine ingredient derived from green tea with a very high L-theanine content of 98%. The high level of standardisation means that the ingredient consists predominantly of L-theanine and provides a consistent amount of the active amino acid in each capsule. For us, the purity and quality of the ingredient are essential, which is why we choose concentrated and well-defined ingredients over simpler alternatives with a lower content of the active substance.

High-quality L-Theanine

Greatlife L-Theanine is a pure, highly concentrated L-theanine product, free from dairy, soya, sugar, gluten and GMOs, as well as artificial sweeteners, colours, preservatives, hydrogenated oils, corn syrup and magnesium stearate. The product is supplied in a dark glass jar free from BPA, phthalates and other endocrine-disrupting substances. It is manufactured in the EU under high quality and hygiene standards and is suitable for vegetarians and vegans.

L-theanine is often used in food supplements to support mental balance, focus and stress management. It is commonly included in formulas for concentration, calm energy and evening relaxation routines. It is also sometimes combined with caffeine to support focused mental performance.
