AI assessment of the formula, label and price. How scoring works
Nutrient Quality60
Several B-vitamin forms support a favorable view of ingredient quality, while riboflavin is less favorable. Missing form and blend details prevent a complete comparison.
Ingredient Transparency72
The listed nutrient and blend amounts and most forms are stated. The blend contents and B5 mixture proportions are not disclosed, leaving parts of the formula unclear.
Value For Money55
Value is favorable for riboflavin and B6, but weaker for vitamin B5, choline and thiamin. Several other nutrients cannot be compared reliably on value, leaving a mixed picture for the combination.
Customer Satisfaction77
Customer ratings are very positive. Several hundred ratings provide a useful picture of satisfaction, without proving an energy boost.
Product Focus35
The B vitamins support normal metabolism and can help with tiredness caused by low intake. The 100 mg B6 serving raises a concern about sensory nerve damage with long-term use, limiting suitability for routine supplementation.
