Food supplement
with L-theanine
L-theanine by Dr. med. Michalzik
For inner calm, clear thinking, and strong nerves: This high-quality food supplement combines pure L-theanine from premium green tea extract with organically bound magnesium. Developed by Biotikon® and verified by doctors – vegan, laboratory-tested, and free from additives.
L-theanine is a unique amino acid found almost exclusively in the leaves of green tea (Camellia sinensis). It has been appreciated for centuries for its ability to combine relaxation with mental alertness. Modern studies show that L-theanine can promote alpha waves in the brain – a state associated with calmness, concentration, and mental clarity.
Especially in combination with magnesium, L-theanine unfolds its full potential: magnesium contributes to normal nervous system function, helps reduce tiredness, and supports normal psychological function. At the same time, magnesium supports muscle function – ideal during periods of high mental or physical stress at work, in studies, or in sports.
Our L-theanine is derived from certified premium green tea extract and processed especially gently. Each batch is strictly laboratory-tested to ensure purity and quality. The formulation is completely free from separating agents, colorants, and preservatives – for maximum naturalness.
The capsules offer flexible dosing with 100–200 mg of L-theanine per daily portion. This is complemented by 35.8–71.6 mg of highly bioavailable magnesium in the form of magnesium bisglycinate.
The most important bioactive compounds in our product include:

Made in Germany
Theanine by Dr. Michalzik is subject to strict examinations of German supervisory authorities. It is manufactured by use of gentle production technologies without heat or additives in the capsule filling and without the use of processing agents which are not required to be mentioned on the packaging.
No industrially produced silicic acid (silicon dioxide) flow aid.
Biotikon does not use silicon dioxide or silicic acid (SiO2, known as E551) as a flow aid. The foundation for product testing "Stiftung Warentest" states that those may contain nanoparticles. Silicic acid or silicon dioxide in dietary supplements has been discouraged. Bio Suisse has terminated approval of silica or silicon dioxide. Silica from horsetail is not to be confused with this industrially produced silica.
No Aluminum Contained
A large number of nutritional supplement providers use aluminum as a sealant for cans. During the sealing process an aluminum foil is strongly heated by a high frequency electromagnetic field. We deliberately do not use this method!
Without talcum!
The release agent and lubricant talcum which is used for manufacturing of tablets or capsules can contain asbestos fibers. Biotikon completely dispenses with the use of release agents and lubricants in their capsule production.
Fresh Products!
From the date of sale all of our products have a long lasting shelf life. This is possible because we process in house.
Food Safety HACCP
Biotikon products are manufactured in accordance with legal requirements and in compliance with the HACCP concept 
in order to ensure food safety.
