A substantial 300 mg L-theanine amount may support calm attention and relaxation. Most of the formula, however, sits inside a 1,050 mg proprietary extract blend whose ingredients and amounts are not disclosed.
The known theanine portion may suit people seeking stronger calming support. The hidden blend prevents reliable assessment of cognitive value, sedation, interactions, or formulation coherence.
Three capsules are needed per serving, and the serving cost is high. Generic theanine sourcing and extensive blend opacity make this much harder to evaluate than transparent alternatives.

.Named actives have amounts, but the proprietary blend is only partly disclosed. A proprietary blend hides the amounts of its individual components.
.The supplied aggregate rating is strong, although no specific comments are included. The moderate rating count provides a useful aggregate signal.
.Formula quality provides strong support for the product positioning. Dose-adjusted serving value appears weak, while opaque or lightly dosed additions reduce efficiency.
.The disclosed theanine amount may support relaxation before bed. It provides 300 mg of L-theanine alongside a large proprietary extract formula for a defined sleep-related pathway.
The generic source lacks a purity standard and the proprietary blend hides the identity and amounts of other actives. The large undisclosed extract blend makes ingredient-specific interactions and tolerability difficult to assess.
A 300 mg L-theanine serving provides strong non-sedating calming support. The large proprietary extract blend may add complementary botanicals, but its hidden contents and doses cannot be verified.
Theanine itself is well dosed and clearly identified, while most of the formula remains opaque. Unknown blend ingredients prevent a reliable check for stimulants, sedatives, interactions, or unnecessary repetition.
A substantial L-theanine amount may support calm attention and reduce stress-related distraction. The much larger proprietary extract formula cannot be assessed for focus, energy, or safety.
The theanine amount is clear and useful, but the hidden blend dominates the formula. Missing ingredient identities and doses prevent a dependable productivity assessment.
L-theanine supplies a meaningful calming-focus mechanism that may support attention under stress. The remainder of the formula cannot be evaluated because its herbal extracts are hidden in a proprietary blend.
The 300 mg theanine amount provides strong depth for relaxed attention. Hidden ingredient identities and doses prevent judging whether the large blend adds useful synergy, sedation, or unnecessary padding.
L-theanine at 300 mg provides substantial support for calm attention. The large proprietary extract formula prevents evaluation of the remaining cognitive claims.
The disclosed theanine has useful depth, but the hidden ingredients make pathway breadth and interaction logic uncertain. A formula dominated by an opaque blend offers much less confidence than the clearly listed active suggests.
A substantial 300 mg L-theanine amount may support calm focus, but it may also feel sedating for some users. The much larger proprietary extract formula prevents a clear understanding of the product's other cognitive or calming effects.
Theanine is disclosed separately, while the remaining blend is opaque. Unknown ingredients and amounts create avoidable safety and interaction uncertainty even though the named active itself is straightforward.
A substantial L-theanine amount may support calmness and lower stress-related tension. The much larger proprietary extract formula hides most ingredients, so the product's broader mood effects and interaction risks cannot be judged.
Theanine is disclosed separately, while the majority of the formula is opaque. Unknown ingredients and amounts create avoidable safety uncertainty despite the straightforward named active.
| Ingredient | Amount per serving |
|---|---|
L-Theanine | 300 mg |
Proprietary Extract Formula | 1050 mg |
The clearly identified L-theanine provides a substantial amount that may support relaxation, though the higher serving may feel sedating for some people. The generic source lacks a branded form or stated purity standard, leaving its quality less certain. The dose is disclosed separately, but the cost efficiency is only moderate for the amount supplied.
