63 out of 100

Vitamin B-12 500 mcg may help fill a B12 shortfall and support normal blood formation and energy use. Extra B12 has no established energy or productivity benefit when your intake is already adequate.

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

Nutrient Quality40

Cyanocobalamin is identified, but its particular quality cannot be judged from the available evidence. The named form alone does not establish better results.

Ingredient Transparency100

The B12 amount and form are both disclosed. That makes the simple formula easy to identify and compare.

Value For Money40

Value for the B12 content remains uncertain. The available information does not support calling it either a bargain or poor value.

Customer Satisfaction91

Customers report very positive satisfaction across a large number of ratings. The extensive feedback offers a firmer picture of satisfaction, rather than proof of health effects.

Product Focus66

The single-nutrient formula is most relevant to filling a B12 gap. Extra B12 does not establish better hair growth, energy or productivity when nutritional needs are already met.
