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

Nutrient Quality40

The B12 form is named, but its quality has not been established. Naming a form alone does not show how it compares with alternatives.

Ingredient Transparency100

The amount and form are clearly disclosed. That makes it easier to check the serving and compare B12 options.

Value For Money40

Value for money remains uncertain. There is no usable B12 price comparison to support a stronger conclusion.

Customer Satisfaction85

Customer feedback is consistently positive across a large number of ratings. That provides a broader view of satisfaction, without proving effectiveness.

Product Focus30

A single B12 ingredient keeps the formula focused. Support for its intended benefits is limited.
