L-Theanine is a unique amino acid found almost exclusively in the leaves of the tea plant (Camellia sinensis). Unlike other amino acids, it is not used to build muscle, but acts as an active molecule. It is responsible for that characteristic feeling associated with tea: an "attentive calm" that sets it apart from the nervous excitement produced by black coffee.
It is 100% natural. It comes from the extraction of green tea leaves.
Yes, there is L-Theanine produced artificially through chemical synthesis. However, you must be careful: in the European Union, synthetic L-Theanine is generally classified as a Novel Food and its use is not freely authorised in food supplements. For your safety and to strictly comply with regulations, PLENIAGE® uses only L-Theanine naturally extracted from green tea (Camellia sinensis), which is the biologically active form, safe and fully permitted in Europe.
EGCG is a type of catechin (polyphenol) found naturally in green tea leaves. It is known to be a powerful antioxidant, but it is also the component responsible for the bitter taste of tea and, when concentrated in supplements, requires special safety precautions.
For liver safety and purity. The European Union has issued warnings about consuming high doses of EGCG in supplements, as they can affect liver health. At PLENIAGE®, we have decided to eliminate it completely through selective filtering. This allows us to offer you a product that is 100% focused on mental relaxation (L-Theanine) without burdening your liver with unnecessary or potentially irritating compounds.
No. Our purification process completely removes caffeine from the tea. This is a great advantage: it allows you to drink it at any time or, if you prefer, combine it with your own coffee (stacking) to ease nervousness without the risk of over-stimulation.
Each capsule contains 200 mg of pure L-theanine. This is the standard dose used in most scientific research to obtain benefits in attention and relaxation without excessive sedative effects. These 200 mg of pure L-theanine are extracted from 500 mg of green tea extract (standardised to 40% L-theanine).
You shouldn't. At a dose of 200 mg, L-Theanine promotes relaxation but not heavy sedation (unlike valerian or pharmaceutical drugs). It is designed to keep you functional, ideal for working or studying calmly.
A: No. L-Theanine is an amino acid that occurs naturally in the diet (tea) and is not considered to be addictive or physically dependent. You can safely incorporate it into your daily routine.
Yes. L-Theanine is a water-soluble amino acid and is well absorbed both with food and on an empty stomach. Many users prefer to take it on an empty stomach in the morning to maximise absorption speed, although if you have a sensitive stomach, accompanying it with a small snack is also fine.
It is our commitment to purity. Fibregum™ is a 100% natural acacia fibre that we use as an excipient to give body to the capsule. We replace synthetic additives (such as magnesium stearate) with this plant fibre to protect the active ingredient in a clean way.
It is a gluten-free, lactose-free formula suitable for vegans (vegetable capsule).
