Analysis

This is the same premium softgel formula as the larger bottle but in a smaller trial size. It combines 200mg of Suntheanine with melatonin and 5-HTP for a very thorough approach to rest. The Suntheanine is particularly good for helping you reach a state of calm alertness before you fall asleep.

It is a solid option for travel or for those who only need sleep support occasionally. The softgel form is easy on the stomach and keeps the ingredients fresh. It is one of the most reliable sleep mixes available.

Pros

  • High-purity Suntheanine
  • Easy to swallow
  • Covers multiple sleep pathways
  • Convenient small bottle size

Cons

  • Not the best value compared to larger bottles
  • Serving size is two softgels
  • Melatonin dose is fixed at 3mg

Warnings

  • May cause grogginess if taken too late
  • Avoid if taking mood-regulating prescriptions
  • Do not drive after taking

Suntheanine L-theanine and 5-HTP provide foundational support for neurotransmitter balance and emotional calm in this softgel formula. These ingredients are paired with melatonin to support restorative sleep, which plays a major role in overall stress resilience.

Providing 200mg of branded L-theanine represents a meaningful dose for promoting relaxation without causing significant daytime drowsiness. This product offers deep support for the sleep-stress pathway but lacks adaptogens for daytime HPA-axis modulation.

Suntheanine L-Theanine, 5-HTP, and Melatonin are included in this formula to support foundational recovery and stress modulation. By facilitating deep sleep, these ingredients ensure the brain is adequately rested for the cognitive demands of the following day.

The use of premium branded theanine provides a reliable tool for enhancing mental clarity through stress reduction. This product appears well aligned with the recovery aspect of productivity, though it is not intended for active focus during work sessions.

Moderate effect
F Goal FitA Strength of SupportF CoverageD+ Formula Quality

Suntheanine L-theanine and 5-HTP work with melatonin to support deep nighttime relaxation and sleep quality. The 200mg theanine dose is effective for calm focus, but the melatonin inclusion is intended to trigger sleepiness.

While highly effective for evening rest, the formula is counterproductive for daytime mental focus and alertness. It serves as an excellent recovery aid but is poorly aligned with goals for sharp cognitive performance during active hours.
