Analysis

The formula is most useful for people who want help settling down and falling asleep. Melatonin provides the main sleep-timing support, while L-theanine may help ease mental tension before bed.

The amounts are clearly disclosed, which makes the formula easier to assess. However, 5 mg of melatonin is more than many people need, and the 75 mg of L-theanine plus small herbal extracts offer relatively light supporting coverage.

The gummy format is convenient for anyone who dislikes capsules, but the full serving requires two gummies and offers no sustained-release feature for staying asleep. It fits occasional bedtime use better than someone seeking precise low-dose adjustment or broad daytime stress support.

Who is it for
  • Adults who mainly need help settling down at bedtime
  • People who prefer gummies over capsules or tablets
  • Users who tolerate a moderate-to-high melatonin amount
Best for
  • Sleep-onset support
  • Nighttime stress that makes it hard to wind down
  • Occasional use when a full night of sleep is available

Pros

  • Clearly lists the amounts of all active ingredients
  • Combines sleep-timing and relaxation support
  • Uses the active L-theanine form rather than an unspecified theanine ingredient
  • Convenient gummy format

Cons

  • The 5 mg melatonin amount may be unnecessarily high for some users
  • The L-theanine amount is modest
  • Botanical extracts are present in small amounts
  • No sustained-release feature for overnight sleep maintenance

Warnings

  • The 5 mg melatonin serving may cause next-day drowsiness or vivid dreams, especially in sensitive users.
  • Melatonin, L-theanine, and the calming herbs may have additive sedating effects with alcohol or sleep medicines.
  • Chamomile may be unsuitable for people with a known allergy to chamomile or related plants.

Nutrient quality

68 High impact

L-theanine and specifically named calming herbs support reasonable ingredient identity, but no branded sources or extract standardization are supplied. Melatonin is relatively high while theanine and the herbs are modest, and the gummy base adds low-value carbohydrates.

.

Ingredient transparency

77 High impact

Every listed active has a specific amount and no proprietary blend hides key doses. Plant parts are often named, but serving directions, inactive ingredients, extract strengths, and purity details are not supplied.

.

Customer satisfaction

70 High impact

The supplied aggregate average is favorable and comes from a large rating sample, but no individual feedback is available. Detailed feedback is absent, so repeated complaints and real-world sleep experiences cannot be assessed.

.

Value for money

66 High impact

Several relevant sleep actives support fair formula value, but most supporting ingredients are modest and the melatonin amount is unnecessarily high for some users. Gummy carbohydrates and low-value protein weaken efficiency, while the serving cost is only moderately competitive.

Melatonin · 5 mgTheanine · 75 mg

The formula is built for sleep onset, combining direct circadian support from melatonin with relaxation support from L-theanine. Melatonin carries the strongest evidence, while the low-amount herbal extracts add less certain value.

The core doses are transparent, but melatonin exceeds the preferred lower physiological range and requires a two-gummy serving. Sensitive users may experience next-day drowsiness, and the immediate-release design offers no specific overnight maintenance feature.

The gummy may help users settle when stress mainly appears as difficulty sleeping. It provides 75 mg of L-theanine, 5 mg of melatonin, and small calming-herb extracts for the stated purpose.

The theanine and herb amounts are modest while the melatonin amount is relatively high. The 5 mg melatonin amount may cause next-day grogginess or vivid dreams in sensitive users.

Report overview
Theanine · 75 mg OverallScore70
B+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyF Value

Explicit L-theanine identity confirms the active isomer, but no branded source or purity testing is shown. The clearly disclosed amount is suited to mild support but sits below the optimal range. The gummy provides mild support, but high dose-adjusted cost limits value.

Melatonin · 5 mg OverallScore48
F Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyD Value
The 5 mg dose exceeds the preferred physiological range but remains clearly labeled. Its two-gummy format and lack of sustained release or purity verification weaken dosing precision and quality assurance. Several calming ingredients add breadth, yet the high serving cost and possible morning grogginess remain drawbacks.
