Brain Feed Theanine

Sale price€40,00

Theanine is a fast-acting, non-sedative, natural relaxation supplement that reduces the impact of excitatory pathways in the brain. Each capsule contains the same amount of l-theanine found in 15-20 cups of green tea. L-Theanine benefits relaxation without sedation.

L-Theanine supplements are ideal for;

  • Anyone who wants to relax.
  • Anyone who wants to relax but maintain performance and clarity.
  • Acute stressors such as public speaking or traveling.

Most L-theanine found in dietary supplements is synthetic (e.g., Suntheanine), and it is produced as a racemic using ethylamine and L-glutamine and a multi-phase synthesis. Our l-theanine capsules contain 250 mg of natural theanine extracted from green tea from the mountainous region of the Hunan province in southern central China. We keep it as pure as possible, so you won't find any additives, like lemon balm, of which the mechanism of action, the ability to enter the brain or synergetic benefit is unknown.

how it works;

Human studies show that Theanine stimulates an increase in alpha brain waves indicative of a relaxed but alert mental state. This type of brain wave activity is often referred to as wakeful relaxation which demonstrates increased creativity and improved performance under stress and reduced anxiety.

  • It is absorbed into the bloodstream and enters the brain via the leucine-preferring amino acid transporter system.

  • The relaxing effect leads to increased GABA concentrations leading to overall feelings of calm and well-being. Unlike other conventional calming treatments, the side effects do not include increased sleepiness, slowed reflexes or decreased concentration.
