Product analysis

56 out of 100

MetaCalm combines ingredients that may support relaxation, with theanine offering the clearest link to easing tension. Several preparation details are unspecified, making the combined effects harder to predict.

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

Nutrient Quality51

The identified B6, magnesium and selenium forms have favorable quality findings. Several other forms are unspecified, leaving the quality of much of the calming mixture uncertain.

Ingredient Transparency81

All ingredient amounts are disclosed, making the serving easier to check. Only some forms are named, limiting precise comparisons for the remaining ingredients.

Value For Money30

The mixture offers limited value for several key ingredients, including theanine, taurine and 5-HTP. Uncertain value for other nutrients makes the full formula harder to compare.

Customer Satisfaction71

Customer ratings are favorable. The small review base limits confidence in how broadly those experiences apply.

Product Focus50

Relaxation and sleep provide the clearest purpose, though effects are limited and depend on the preparation. The much wider range of possible uses makes the formula less focused.
