FROM THE MANUFACTURER’S LABEL

Per 1 capsule: L-Theanine 200 mg.

Check the original label ↗

L-theanine is an amino acid found in tea and also sold as a separate supplement. Small human trials have examined stress-related symptoms and aspects of sleep. Tea, isolated theanine and theanine combined with caffeine are different interventions, so the complete formula matters when interpreting research or deciding what effect to expect.

The pack details above come from the manufacturer. Ingredient research below does not establish the effects of this exact product or independently verify its contents.

The complete declared ingredient amounts

The current table uses a serving of 1 capsule. It declares L-Theanine 200 mg. These are manufacturer label amounts, not a personal dosing instruction.

The comparison detail that changes the decision

The capsule supplies 200 mg L-theanine. The 90-capsule count describes the pack, while 200 mg is the amount in a single labelled serving. The selected product has 90 labelled servings per container. Matching ingredient form and serving matters more than bottle count.

Excipients, cautions and evidence limits

Other listed ingredients: Leucine, Microcrystalline Cellulose, Calcium Laurate, Hypromellose (derived from cellulose) capsule. Review other calming products and medicines before combining them. Theanine is not a substitute for assessment of persistent anxiety or insomnia. No independent batch test or exact-formula clinical outcome was verified in this review. Current Indian stock and delivered price remain unverified.

02 / BENEFITS, IN PERSPECTIVE

Where might it be useful?

01

Possible stress-related effects

A small randomized study reported improvement in some stress-related measures after short-term L-theanine use.

02

Possible sleep-related effects

The same research explored sleep measures, providing preliminary findings rather than a guaranteed sleep benefit.

THE EVIDENCE LENS

What the research can — and cannot — tell us

The cited trial was small and short, with results that need replication in broader populations. It does not establish treatment of anxiety disorders or chronic insomnia. Effects of a specific theanine preparation should not be assumed for every capsule, blend or drink, particularly when caffeine is added.

03 / A CLOSER LOOK

What deserves your attention?

Review other calming products and medicines before combining them. Theanine is not a substitute for assessment of persistent anxiety or insomnia.

Suitability comes before strength

Check blends for caffeine and other sleep or mood ingredients. Discuss persistent insomnia, anxiety, pregnancy or medicine use with a clinician. Avoid assuming that a supplement will be effective or appropriate simply because the ingredient occurs in tea.

Dietary details for this product

Dietary status not confirmed The reviewed current label does not explicitly establish vegan or vegetarian status for the complete formula. A cellulose capsule or dairy-free statement alone is not a whole-formula declaration.

A dietary label and an allergy assessment answer different questions. Check every ingredient, the capsule or softgel materials and the allergen statement on the pack you receive. If you take medicines, have a health condition, are pregnant or are choosing for a child, discuss the full formula with a qualified clinician.
