Product analysis
Lights Out Sleep combines melatonin with calming ingredients to support sleep timing and help with winding down. Several ingredients have mixed evidence, so the broad blend does not mean every part will make a noticeable difference.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality28
Ingredient quality is difficult to judge across much of the blend. Several preparations are unspecified, while the named forms alone do not confirm their quality.
Ingredient Transparency78
Amounts are clearly disclosed, which helps you compare what each serving provides. Several ingredient forms are unspecified, making comparisons between preparations harder.
Value For Money31
The blend offers limited value when judged by its 5-HTP, theanine and melatonin content. Value for several other ingredients remains unclear, so a long ingredient list does not establish a better buy.
Customer Satisfaction71
Customers give generally positive feedback across several hundred ratings. The feedback does not establish whether the blend improves sleep or is suitable for a particular person.
Product Focus76
Sleep support is the clearest purpose, with melatonin supporting sleep timing and theanine offering a calming connection. Smaller amounts and mixed findings limit how much several other ingredients can contribute.
