Analysis

Three capsules provide 100 mg branded Suntheanine, 50 mg elemental magnesium from 500 mg magnesium malate, 30 mg saffron extract, and smaller amounts of lemon balm, passionflower, lavender, valerian, and magnolia. The formula covers several calming and mood-related pathways with individually listed weights.

Suntheanine offers strong source confidence, while saffron and magnolia add distinct support beyond common sleep herbs. Valerian at 50 mg is too low and undefined to contribute much, and the label appears to repeat saffron and magnolia marker amounts in a way that complicates interpretation.

Only 30 servings are provided, with three capsules and an exceptionally high daily cost. It fits users who specifically value the branded theanine and multi-botanical design rather than simple sleep support.

Who is it for
  • Adults seeking a premium calming capsules
  • Users whose needs match the disclosed ingredient amounts
  • People who can screen ingredient-specific medication and tolerance concerns
Best for
  • Comparing form, dose, and practical value
  • Goal-aligned supplement selection
  • Users who prefer a premium calming capsules

Pros

  • Uses branded Suntheanine
  • Includes saffron and magnolia
  • Adds magnesium malate
  • Lists each botanical amount

Cons

  • Very high serving cost
  • Requires three capsules
  • Only 30 servings
  • Valerian amount is only 50 mg
  • Some marker amounts are ambiguous

Warnings

  • The combined theanine, lemon balm, passionflower, lavender, valerian, saffron, and magnolia may cause drowsiness or next-day impairment
  • Saffron may add to antidepressant effects and deserves review with serotonin-modulating medicines
  • Magnolia and other calming herbs may compound alcohol or sedative medicines
  • Turmeric may increase bleeding concern with anticoagulant or antiplatelet medicines

Nutrient quality

67 High impact

Branded theanine, saffron, and magnolia markers improve form quality. Elemental magnesium and most botanicals are modest, creating more breadth than depth around the two strongest actives.

Ingredient transparency

79 High impact

Listed active ingredients have specific weights and no proprietary blend hides their doses. Complete use directions and a full other-ingredients list are not included in the supplied facts.

Customer satisfaction

59 Moderate impact

The supplied average rating is strong, and the small review sample limits confidence. No detailed comments are provided to assess repeated complaints or whether experiences match the intended use.

Value for money

26 Situational impact

Weak dose efficiency or high recurring cost limits practical value. Incomplete form, activity, or use details remain the main value trade-off.

Several herbs are supplied at small amounts, including valerian, and elemental magnesium is modest. The formula is coherent but relies on many partially dosed calming ingredients rather than a few deep pathways.

Branded theanine, magnesium, saffron, and several calming herbs create a broad bedtime relaxation strategy. The concept is sleep-specific, but many herbs appear at token levels.

Suntheanine is well identified at 100 mg, while elemental magnesium is only 50 mg and valerian is far below typical use. Missing standardization for several botanicals makes the crowded label stronger in breadth than depth.

Suntheanine, saffron, magnesium, and calming botanicals may reduce stress that interferes with cognition, but the formula is not directly focus-oriented. Suntheanine at 100 mg and saffron extract at 30 mg are meaningful, while 50 mg elemental magnesium and most herbs are modest.

The formula addresses calm attention and stress-related cognitive interference without strong cholinergic or circulation support. The calming stack is internally consistent, though valerian and other sedating herbs may work against daytime focus.

Branded L-theanine provides credible calm-focus support, while magnesium and saffron may help reduce tension. Several additional herbs are more sedating than focus enhancing and may reduce alertness for some users.

The formula is better suited to relaxation than demanding cognitive work. Valerian, passionflower, lemon balm, lavender, and magnolia may cause drowsiness, so use before driving or other alertness-dependent tasks is not appropriate.

Theanine, magnesium, saffron, and calming botanicals may reduce stress, but the heavily sedating direction can work against productivity. Theanine and some botanicals have human calming evidence, while the multi-herb stack lacks strong evidence for improved work performance.

The formula covers calm and stress response but omits alertness, cognitive precursors, and fatigue resistance. The ingredients share a relaxation strategy, but valerian, passionflower, lavender, and magnolia may promote drowsiness in some users.

Report overview
A+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD+ Value

Suntheanine supplies a branded, high-purity form at a well-aligned amount. Magnesium, saffron, and several calming botanicals broaden relaxation support beyond theanine alone. The cost per active amount is high, but the branded source and substantial supporting formula improve the practical value.

Valerian · 50 mg OverallScore40
F Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyF Value

An undefined valerian form prevents a meaningful potency assessment. The 50 mg amount is too low to provide meaningful valerian support. A token amount and undefined form create poor valerian-specific value.
