Product analysis

54 out of 100

B 100 Complex supplies B vitamins that help the body use food for energy and fill nutritional gaps. Missing amounts for several added ingredients and an undisclosed blend make the extra ingredients harder to judge.

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

Nutrient Quality54

Some B-vitamin forms are clearly identified, while the quality of several added ingredients remains uncertain. The mix includes ordinary riboflavin and folic acid, which are less favored forms in their respective comparisons.

Ingredient Transparency53

Most B-vitamin amounts are stated, but several added ingredients have no individual amount. Missing forms and an undisclosed blend also limit a full comparison.

Value For Money56

Value varies across the mix, with favorable costs for riboflavin and B6 but weaker value for B5 and some other nutrients. The added ingredients do not all have enough information for a reliable value comparison.

Customer Satisfaction79

Customer feedback is highly positive across hundreds of ratings. That provides a useful picture of satisfaction, without proving extra energy or other health benefits.

Product Focus25

The strongest fit is filling gaps in B-vitamin intake and supporting normal energy use. The wider collection of added ingredients and claims does not establish extra benefit when nutritional needs are already met.

Vitamin B5 · 100 mgRiboflavin · 100 mgThiamin · 100 mgVitamin B12 · 100 mcg

Thiamin, riboflavin, niacin, pantothenic acid, B6 and folate support normal energy metabolism or correction of deficiency-related tiredness. Higher vitamin amounts do not establish more energy in people whose intake is already adequate. B12 is present at 100 mcg per serving but is below the saved contribution threshold. Other plant and nutrient ingredients broaden the formula without establishing additional energy benefits.

How this product is rated for Energy

Ingredient fit77

Six B vitamins contribute, with several other actives broadening the formula.
Goal fit
Six B vitamins contribute, with several other actives broadening the formula.
Dose adequacy
The six credited vitamins reach the saved amount references; B12 is not counted at this amount.

Pathways0

The contribution concerns nutrient sufficiency; no listed direct alertness, exercise or stress-fatigue pathway receives coverage.
Depth
No listed direct energy pathway receives coverage from the credited nutrients.
Breadth
No listed pathway reaches the coverage threshold.

Evidence78

Riboflavin provides the strongest recognized evidence contribution at its saved amount. Its practical benefit remains subject to the population and nutrient-status limits described above.
Evidence strength
Riboflavin leads the evidence contribution among ingredients at recognized amounts.
Studied preparation
The credited ingredients meet the saved preparation criterion; this does not establish benefit for every user.

Formulation logic100

The credited ingredients require no missing partner, and no configured conflict was found. All credited amounts pass the saved minimum contribution threshold.
Partner coverage
Every credited ingredient can contribute without a missing required partner.
Conflicts
No configured ingredient conflict was identified.
Effective doses
All credited ingredients pass the saved minimum amount threshold; this is not proof of a clinically effective dose.
