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

Nutrient Quality40

The B12 form is clearly identified, but its relative quality remains uncertain from the available information. The form name does not establish an extra health advantage.

Ingredient Transparency100

The B12 amount and form are clearly stated. That makes the declared serving easy to compare.

Value For Money40

Value for money cannot be judged reliably. There is not enough information to compare the B12 contribution with the serving cost.

Customer Satisfaction92

Customer feedback is highly positive across many thousands of ratings. The large response count gives a broad picture of satisfaction.

Product Focus66

B12 supports normal blood formation, nerve function and energy use. Extra energy, productivity or hair growth is not established when B12 needs are already met.
