Product analysis
Genius Sleep Aid may help with sleep timing and falling asleep, while theanine may offer a calming contribution.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality50
Theanine is identified in its favorable L-form. Several other preparations are unspecified, so their quality is less clear.
Ingredient Transparency78
All ingredient amounts are stated, making the serving easier to compare. Only theanine and rutaecarpine have named preparations, leaving several form details unresolved.
Value For Money30
The full serving cost makes theanine and melatonin relatively expensive. Reliable value comparisons are unavailable for glycine and inositol.
Customer Satisfaction90
Customer ratings are strongly favorable across a substantial review base. The review volume gives those opinions more context without proving a sleep benefit.
Product Focus60
The clearest purpose is bedtime sleep support, mainly through melatonin. Theanine may contribute calmness, but the sleep-oriented combination does not fit a goal of daytime alertness.
