What is L-Theanine?


  • L-Theanine is an amino acid that is commonly found in tea leaves. It is also a popular natural supplement used for cognitive enhancement. The supplement form of the substance is extracted and purified to produce a fine white powder.
  • L-Theanine is widely known for its ability to promote feelings of calmness and relaxation, without producing feelings of sedation; something that can be so useful in the fast-paced, non-stop society that we find ourselves in.
  • Due to these properties, it is extremely effective in counteracting common side effects of caffeine, such as the 'jitters'. When combining these two substances feelings of wakefulness and focus can be achieved, while staying very calm and relaxed.
  • If you’re interested in enhancing this incredible double edged effect of wakefulness and focus alongside feelings of calmness, check out our Caffeine & L-Theanine combined capsules.

How Much Should I Take?

The recommended dose of L-Theanine is between 100mg - 500 mg daily. It is recommended that when being used alongside caffeine, roughly a 2:1 ratio in the favour of L-Theanine should be used.
