Product analysis

40 out of 100

Power to Sleep PM 6 mg Melatonin centers on melatonin to help with sleep timing and falling asleep. The undisclosed herbal blend makes the full combination harder to judge.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality22

Calcium and magnesium forms are identified, but most other forms are unspecified. The undisclosed herbal blend also limits a clear judgment of ingredient quality.

Ingredient Transparency54

Amounts are listed throughout, but most forms are unspecified. The herbal blend does not identify its individual components, leaving the full recipe unclear.

Value For Money36

The cost compares poorly for theanine and melatonin, while GABA offers limited value. Value for most of the remaining ingredients is uncertain.

Customer Satisfaction75

Customer ratings are generally very positive. A substantial number of ratings gives a broad view of customer satisfaction.

Product Focus28

Melatonin provides the clearest link to sleep timing and onset. Support for lasting stress relief or everyday mood is less certain, and several supporting amounts do not match the preparations associated with benefits.
