Melatonin 2 mg may help with sleep timing and shorten the time it takes to fall asleep. Its usefulness depends on when it is taken and the person’s sleep pattern.

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

Nutrient Quality20

The melatonin and glycine forms are unspecified. Their relative quality cannot be judged confidently from the amounts alone.

Ingredient Transparency63

Both ingredient amounts are disclosed, making the serving clear. Neither form is specified, limiting a closer comparison with other preparations.

Value For Money50

The melatonin offers moderate value per serving. Glycine is less attractive for the amount provided and adds little supported sleep contribution at this serving.

Customer Satisfaction70

Customer ratings are favorable. The small review base limits confidence in how widely that experience applies.

Product Focus92

Melatonin gives the formula a clear sleep-related purpose. The glycine amount is far below the amount associated with preliminary sleep findings, so it adds little supported contribution.
