SYMNUTRITION L-Teanina 200mg, 150 Cápsulas

What is L-Theanine?

L-Theanine is an amino acid naturally found in green and black tea leaves, known for its relaxing properties without inducing drowsiness. This SYMNUTRITION supplement offers 200 mg of pure L-Theanine per capsule, in a presentation of 150 vegan, non-GMO, and gluten-free capsules. Manufactured in a cGMP registered facility in the United States, it guarantees purity and potency in every dose.

Main Benefits and Uses

L-Theanine has earned a reputation for its ability to promote a state of calm and mental clarity. Many users take it to manage daily stress, improve concentration, and support restful sleep. Some studies suggest it can increase the production of alpha waves in the brain, associated with alert relaxation. Combined with caffeine, it enhances focus and mental energy without the typical jitters of coffee. It is a popular choice among students, professionals, and anyone looking for natural support for cognitive performance and emotional balance.

How does it work?

L-Theanine crosses the blood-brain barrier and modulates the activity of key neurotransmitters such as GABA, serotonin, and dopamine. By increasing GABA levels, it produces a calming effect, while increased serotonin and dopamine contribute to improved mood. Unlike pharmacological anxiolytics, it does not cause dependence or excessive drowsiness, making it a mild and effective alternative for managing daily stress.

Dosage and Recommendations

The recommended dose is one 200 mg capsule daily, preferably on an empty stomach or with food. For a more pronounced relaxing effect or to aid sleep, an additional capsule can be taken up to a maximum of four daily, following the manufacturer's instructions. Do not exceed the recommended dose. It is important to consult a healthcare professional before starting any supplementation, especially if you are pregnant, breastfeeding, or under medical treatment.

Side Effects and Contraindications

L-Theanine is generally safe and well-tolerated. At high doses, some people may experience mild headaches or gastrointestinal discomfort. No serious drug interactions have been reported, but caution is advised if taking antihypertensives or stimulants. This supplement should not be used as a substitute for medical treatments for anxiety or insomnia. Keep the product out of the reach of children.
