AI assessment of the formula, label and price. How scoring works
Nutrient Quality53
Some B-vitamin forms are favorable or clearly identified, while others are less favorable. Several missing forms and uncertain quality for other ingredients make the mix uneven.
Ingredient Transparency86
All listed amounts and many ingredient forms are disclosed. Several form omissions leave part of the label less clear for comparison.
Value For Money46
B6 offers good value for its declared amount, while vitamin C and riboflavin offer moderate value. Several other portions are relatively costly, leaving value mixed across the formula.
Customer Satisfaction89
Customer ratings are very positive across thousands of reviews. The broad feedback reflects satisfaction without establishing lasting stress relief.
Product Focus57
The clearest role is filling nutrient gaps to support normal body functions. The high B6 serving raises a suitability concern without establishing stronger benefits.
