AI assessment of the formula, label and price. How scoring works
Nutrient Quality30
Theanine and fenugreek forms are unspecified in the main listing, limiting quality comparisons. Vitamin D and lemon balm forms are identified, but their quality remains uncertain.
Ingredient Transparency65
All ingredient amounts are disclosed, so serving quantities are clear. Half the relevant forms and one composition detail remain unspecified.
Value For Money48
Fenugreek offers favorable value at the serving cost, while theanine is more middling. Vitamin D and lemon balm value remains uncertain.
Customer Satisfaction63
Customer ratings are generally positive, but the review pool is small. The limited volume makes the satisfaction signal less settled.
Product Focus58
The clearest contribution is modest short-term relaxation from theanine, with attention and sleep effects less certain. The mixture spans several goals rather than concentrating on one clearly established role.
