Analysis

Two capsules provide 300 mg valerian extract, 200 mg L-theanine, 80 mg passionflower, 30 mg hops, and 2 mg vitamin B6. Theanine reaches a strong calming amount, while valerian provides a moderate extract weight.

The ingredients are coherently directed toward sleep and stress relief rather than daytime productivity. Missing valerian extract ratio and valerenic-acid standardization reduce potency confidence, while passionflower and hops are supportive rather than dominant.

Thirty servings and a moderate-to-high daily cost limit long-term value. It fits users who want a clearly dosed theanine-centered nighttime blend and tolerate two capsules.

  • Adults seeking a sleep-and-stress 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 sleep-and-stress capsules

  • Requires two capsules
  • Valerian is not standardized
  • Serving cost is above average

Warnings

Nutrient quality

80 Highest impact

Theanine receives a strong amount, while valerian is useful but unstandardized and the remaining herbs are modest. The formula is focused, though overlapping calming ingredients increase drowsiness risk.

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

67 High impact

The supplied average rating is moderately favorable, and review volume provides a useful but limited signal. No detailed comments are provided to assess repeated complaints or whether experiences match the intended use.

Value for money

69 High impact

Useful core ingredients provide fair value, but formula limitations reduce competitiveness. Incomplete form, activity, or use details remain the main value trade-off.

L-theanine and valerian provide complementary support for mental calm and stress-related sleep difficulty. The formula is better suited to evening relaxation than to maintaining alert performance during daytime stress.

The 200 mg L-theanine amount is strong, while the valerian amount is useful but lacks extract-standardization details. Valerian, passionflower, and hops may combine to cause drowsiness, so the capsules can impair alertness.

Valerian, theanine, passionflower, and hops create a coherent bedtime relaxation blend. It covers several calming mechanisms but does not directly regulate circadian timing.

Theanine and valerian have useful disclosed amounts, while passionflower and hops play smaller supporting roles. The formula is focused and free of stimulants, though standardized extract details are limited.

L-theanine, valerian, passionflower, hops, and vitamin B6 form a focused calming and sleep-support blend. The formula may help tension related to poor sleep, but it is less suited to broad daytime mood regulation.

Theanine is meaningfully dosed, while valerian lacks an extract ratio or valerenic-acid standardization. Valerian, passionflower, and hops may cause additive drowsiness, so the blend is unsuitable before driving.

L-theanine may support calm attention, while valerian, passionflower, and hops shift the formula toward sleep. The 200 mg L-theanine amount is meaningful and clearly disclosed.

Daytime cognitive support is limited because several botanicals can be sedating rather than focus enhancing. Valerian, passionflower, and hops may cause drowsiness and can intensify the effects of alcohol, sleep medicines, or other sedatives.

Theanine can support calm concentration, but valerian, passionflower, and hops make the blend more sedating than focus-enhancing. The product is better aligned with evening relaxation than daytime cognitive performance.

Theanine is fully dosed and every ingredient amount is disclosed. Valerian, passionflower, and hops may cause drowsiness, so the blend is poorly suited before driving or concentration-heavy work.

B+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyB+ Value

The clearly identified L-theanine provides an effective 200 mg serving for relaxation support. Its generic form lacks a branded purity standard, but the exact amount is fully disclosed. Value is competitive, and the added valerian, passionflower, and hops make the blend more oriented toward sleep and calming than daytime focus.

Valerian · 300 mg OverallScore63
C- Active Ingredient Quality & BioavailabilityB Dose, Safety & Label TransparencyD- Value

The disclosed valerian root extract amount is reasonable for a moderate serving, and capsules help contain valerian's strong odor. Potency is less certain because the label gives no extract ratio or valerenic-acid standardization. The serving cost is above the collection median, which limits value despite clear ingredient amounts.
