Allergy Research Group® 200 mg of Zen (60 or 120 capsules) combines 200 mg of L-theanine with 550 mg of GABA per 2 capsules. L-theanine is an amino acid from green tea, while GABA (gamma-aminobutyric acid) naturally occurs in fermented foods. This combination is convenient for daily use, at any time of the day. The L-theanine in this product comes from Suntheanine® – a pure, patented form produced by fermentation. The capsules are plant-based and easy to take, making them suitable for a regular routine, whether you choose to use them during the day or in the evening.
What is L-theanine?
L-theanine is an amino acid that naturally occurs in green tea (Camellia sinensis). It is especially valued because of its unique combination with caffeine in tea, but is also available in isolated form in supplements.
Is L-theanine an essential amino acid?
No, L-theanine is not an essential amino acid. This means the body does not necessarily need to obtain it from food, as is the case for essential amino acids. It is also not common in standard foods, except in tea.
What is the difference between L-theanine from green tea and Suntheanine®?
Suntheanine® is a patented, pure form of L-theanine that is produced through fermentation. In green tea, L-theanine occurs naturally, but in smaller amounts and always together with other substances such as caffeine. Supplements with Suntheanine® contain only L-theanine in a set quantity.
Where does L-theanine occur naturally?
The main natural source of L-theanine is green tea. It also occurs in smaller amounts in other types of tea, such as white and black tea, but is rarely found in other foods.
What exactly is GABA?
GABA stands for gamma-aminobutyric acid. It is a non-essential amino acid that is also found in fermented foods such as kimchi, miso, and certain types of yogurt. In supplement form, it is often added in fixed amounts.
Is GABA the same as glutamine or glutamate?
No, GABA is related to glutamine and glutamate, but they are three different substances. They are sometimes used separately in foods and supplements, depending on the purpose of the formula.
Does GABA occur in foods?
Yes, GABA naturally occurs in fermented products such as fermented vegetables, yogurt, and certain teas. The amounts in food are usually small and variable.
