Analysis

The tablet combines a preferred-range theanine amount with melatonin and a small nighttime herbal blend. Its design is clearly aimed at sleep rather than daytime focus.

The melatonin amount is relatively high and may cause residual grogginess or vivid dreams. The herbal blend does not reveal individual ingredients or amounts.

The product may suit experienced melatonin users who know they need a strong serving. Lower-dose, fully disclosed sleep formulas offer more flexibility.

Who is it for
  • Experienced melatonin users
  • Adults seeking strong sleep-onset support
  • People not needing next-morning alertness
Best for
  • Bedtime use
  • Sleep onset
  • Theanine plus melatonin

Pros

  • Substantial theanine amount
  • Melatonin amount is disclosed
  • Competitive serving value
  • One-tablet format

Cons

  • Very high melatonin amount
  • Proprietary nighttime blend
  • Poor fit for daytime focus
  • Limited dosing flexibility

Warnings

  • The high melatonin serving may cause next-day grogginess or vivid dreams
  • Do not drive after taking the product
  • Alcohol, sedatives, and other sleep aids may compound drowsiness

Nutrient quality

72 High impact

Generic theanine and an unspecified herbal blend provide limited form assurance. Theanine is meaningful and melatonin is potent, though the herbal contribution cannot be assessed.

.

Ingredient transparency

67 High impact

Every listed active has a specific amount, which makes the core formula straightforward to assess. A partially disclosed blend and missing excipient details leave important uncertainty.

.

Customer satisfaction

59 Moderate impact

The supplied aggregate satisfaction signal is favorable. Limited feedback volume and absent narrative evidence leave the experience less certain.

.

Value for money

68 High impact

Two meaningful sleep actives support fair quality, but the hidden blend and aggressive melatonin amount weaken value. Serving-level value is reasonable for a combined sleep formula.

Theanine and melatonin directly target relaxation and circadian timing in a sleep-specific formula. The small herbal blend adds uncertain support because its ingredients are hidden.

Theanine reaches a preferred amount, but the high melatonin dose may increase morning grogginess or vivid dreams. The tri-layer design suggests staged delivery, though the proprietary herbal blend limits transparency.

L-theanine provides a well-aligned amount for calm attention, while melatonin supports nighttime use. The combination fits stress that interferes with falling asleep better than daytime stress.

The herbal blend hides its individual ingredients and doses, which limits assessment. The 10 mg melatonin amount may cause next-day grogginess or vivid dreams in sensitive users.

Theanine and melatonin support sleep, which may indirectly benefit cognition and mental resilience. Theanine reaches a useful amount, while the herbal blend is too opaque to judge.

The 10 mg melatonin amount is high and may cause next-day grogginess, vivid dreams, or disrupted sleep timing. The formula is coherent for sleep but does not directly support memory or cerebral energy.

L-theanine is well dosed for calm attention, while melatonin and herbs target sleep restoration. Better sleep may support next-day cognitive function, but the formula is not suited to daytime focus.

The melatonin amount is relatively high and may cause next-day grogginess or vivid dreams. A small proprietary herbal blend also prevents full assessment of the nighttime support.

A well-dosed 200 mg L-theanine amount may support calm and reduce stress-related tension. The nighttime design may help mood indirectly when poor sleep is a major contributor.

The 10 mg melatonin amount is high and makes the formula primarily sedating rather than mood stabilizing. It may also increase next-day grogginess or vivid dreams.

The clearly disclosed 200 mg L-theanine amount is well aligned with focused use. Generic sourcing lacks added purity evidence, but cost efficiency is competitive. The added 10 mg melatonin is a relatively high sleep dose that may increase next-day grogginess or vivid dreams.
