L Theanine

What is this?
L Theanine is a relatively uncommon amino acid found in green tea. It is similar in structure to Glutamine; a precursor to GABA and glutamate. It is able to cross the blood brain barrier where it can bind with glutamate receptors and seems to increase levels of serotonin and dopamine.

L Theanine can also increase levels of nitric oxide promoting blood flow and healthy circulation.

Where this interesting compound comes into its own, is its ability to relieve stress and lower anxiety without acting as a sedative. Many people choose to take L Theanine alongside caffeine to reduce some of the negative effects sometimes associated with caffeine, such as jitters and tension.

Focus supplements produce only high quality products, manufactured in the UK at an ISO licensed facility and 3rd party lab tested for purity.

Suggested use
We recommend starting with 200-300mg per day.

L Theanine also stacks well with caffeine at a 2-1 ratio, for example 200mg of L Theanine to 100mg caffeine.
