L-Theanine 100 mg, 30 capsules

L-Theanine, multiple benefits for nervous system health! Reduces stress, improves memory and focus!

L-Theanine is a dietary supplement derived from green tea extract, standardized to 98% L-theanine. L-Theanine is a semi-essential amino acid, meaning the human body cannot produce it naturally. It is naturally found in green tea and certain mushrooms, and it positively influences the secretion of serotonin and dopamine, hormones known for regulating well-being and emotional control. This compound from green tea also has adaptogenic effects, helps manage stress, supports restful sleep, stimulates the immune system, and contributes to maintaining normal blood pressure.

L-theanine enhances brain function and concentration

L-theanine can cross the blood-brain barrier, improving brain activity and focus. It is particularly useful in cases of “writer’s block,” where taking an L-theanine supplement can have a calming effect and help stimulate creativity. Studies comparing L-theanine with caffeine have shown that L-theanine promotes optimal brain stimulation and enhances attention without causing the agitation often associated with caffeine consumption.

L-theanine in anxiety and stress management

L-theanine enhances alpha brainwave activity, producing a state similar to deep meditation. This results in overall calm while also improving focus and concentration. Unlike many anxiety treatments that slow down the nervous system, L-theanine does not cause drowsiness or mental cloudiness. It relaxes without sedative effects and is non-addictive. At doses of 50–100 mg per day, L-theanine increases attention and concentration, making it useful in managing chronic fatigue syndrome. At higher doses of 200–400 mg per day, it can have a calming effect in cases of anxiety and depression.

L-theanine supports the immune system

Studies have shown that L-theanine can help support the innate immune system by regulating the secretion of inflammatory cytokines—molecules that transmit signals between cells and are involved in inflammatory processes and defense against infections. In addition, L-theanine contributes to supporting immunological memory, which is responsible for antibody production and long-term adaptive immunity.

L-theanine supports restful sleep

Beyond difficulties falling asleep, many people also experience poor sleep quality. Sleep deprivation is associated with a higher risk of various health issues and reduces overall quality of life. Some substances used for insomnia can cause dependency and have multiple side effects. Taking L-theanine before bedtime can help improve sleep quality—not by sedation, but by reducing anxiety, irritability, and tension. Since L-theanine does not induce drowsiness, it can be taken at any time of the day.
