Description & FAQ
L-Theanine (Natural Green Tea Extract) Nootropic Supplements
Our 400mg L-theanine capsules have been designed to keep you focused, stay relaxed, and stay energised.
L-theanine is an amino acid found in plants that mirrors the important molecules – like L-glutamine – found in our own bodies.
It can pass through the blood-brain barrier to engage with your brain’s receptors, helping to increase the levels of “feel-good” hormones like dopamine and serotonin so you can stay mentally alert and calm.
Does L-Theanine make you sleepy?
L-theanine can contribute to a healthy sleep pattern. It’s thought to do this by increasing levels of serotonin and dopamine, helping you to feel relaxed without causing feelings of drowsiness!
Does L-Theanine make you focus?
L-theanine has been used to help increase focus for centuries. Scientific research has shown that L-theanine can help to improve focus and cognitive function, with subjects demonstrating better attention, shorter reaction times, and better memory.
How long does L-Theanine take to kick in?
While it is different for everyone, most people tend to feel the effects of L-theanine around 40-60 minutes after ingestion. Other users report feeling the effects in 30 minutes or less.
