L-Theanine Nootropics Next Valley

L-Theanine

L-Theanine is, as the name suggests, a substance that occurs naturally in tea leaves. In 1950 it was already extracted from gyokuro leaves, a type of green tea.

The substance Theanine is an amino acid, in other words a building block for proteins. Although it occurs naturally in tea, supplementation is the main source of L-Theanine. L-Theanine has structural similarities to glutamine. It affects several neurotransmitter systems in the brain (Dop@mine, GABA, Glutamate, Serotonin).

L-Theanine is quickly absorbed after ingestion and is often combined with Caffeine or Magnesium for cognitive support.

Despite several studies on nootropics, no health claim can and should not be made on the effect and properties of the products. Read the instructions before use!
