Product analysis
Intrinsi B12-Folate can help cover B12 and folate gaps, supporting normal blood formation and helping when low nutrient levels cause tiredness.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality38
Folate and B12 forms are identified, but their quality remains uncertain. Intrinsic factor lacks a precise form declaration, leaving that part less clear.
Ingredient Transparency88
Ingredient amounts and both vitamin forms are stated. Intrinsic factor lacks a precise form declaration, making that ingredient harder to compare.
Value For Money40
Value for the vitamin combination and intrinsic factor remains uncertain. A firm judgment about whether the formula is economical is not possible.
Customer Satisfaction71
Customer feedback is positive, but it comes from a relatively small number of ratings. That limits confidence about broader buyer experience.
Product Focus69
The short formula focuses on B12 and folate nutrition, including normal blood formation. Benefits for tiredness and concentration mainly depend on low nutrient levels, with no established added benefit from intrinsic factor.
