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.

How Can L-Theanine Benefit Me?

Supplementing L-Theanine daily can:

  • Promote feelings of calm and relaxation. Lessen those daily feelings of stress.
  • Increase cognitive performance. Stay sharp but relaxed.
  • Counteract negative side effects of caffeine. No more 'jitters'.
  • Increase productivity when combined with caffeine.
