Product analysis
B-Complex 100 supplies B vitamins that can help fill dietary gaps and support normal metabolism. Its high vitamin amounts do not establish extra energy when nutritional needs are already met.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality58
Several B-vitamin forms are clearly identified, making those sources easy to compare. Folate, biotin and some additional ingredient forms remain unspecified.
Ingredient Transparency86
The listed ingredient amounts are disclosed throughout the formula. Some forms are missing, leaving less clarity about the exact sources of those ingredients.
Value For Money49
Value varies across the formula, with vitamin B6 and riboflavin among the stronger contributions for the serving cost. Several other nutrients offer less value or lack enough information for a reliable comparison.
Customer Satisfaction82
Customer ratings are strongly positive across a sizeable set of reviews. The feedback supports a favorable view of satisfaction without establishing energy or other health effects.
Product Focus68
The clearest purpose is supporting normal nutrition and metabolism when intake is low. The 100 mg B6 serving raises concern about nerve damage with long-term use.

Vitamin B5 · 100 mgRiboflavin · 100 mgThiamin · 100 mgVitamin B12 · 100 mcg
Riboflavin, niacin, B5, B6 and folate can help address fatigue caused by low intake or deficiency, including anemia-related weakness. Their amounts fully meet the saved comparisons, but high B-vitamin amounts do not establish extra energy when intake is adequate. Thiamin's normal metabolic role also does not prove a routine energy boost. B12 did not qualify at its declared amount, and none of the assessed energy pathways receives coverage.
How this product is rated for Energy
Ingredient fit85
Several B vitamins provide conditional nutritional contributions, with other actives broadening focus.
Goal fit
The B-vitamin mix is relevant to nutritional fatigue, alongside other actives outside the assessed contribution.
Dose adequacy
Six credited vitamins fully meet their saved comparisons; B12 falls below the saved contribution threshold.
Pathways0
None of the assessed energy pathways receives coverage. This differs from the conditional nutritional contribution retained elsewhere.
Depth
No assessed energy pathway has a qualifying contribution.
Breadth
No assessed energy area reaches substantial coverage.
Evidence78
Riboflavin leads the saved support finding; normal metabolism and large B-vitamin amounts do not establish extra energy above adequacy. The preparation meets the saved criteria.
Evidence strength
Vitamin B2 (Riboflavin) leads the saved evidence finding, within the population and outcome limits of its supplied evidence.
Studied preparation
Credited preparations meet the saved criteria without establishing superiority of particular forms or delivery methods.
Formulation logic100
Credited ingredients clear the saved amount threshold and have no assessed missing partner or conflict.
Partner coverage
Credited ingredients work alone or have their relevant partners.
Conflicts
No assessed ingredient conflict was triggered.
Effective doses
All credited ingredients clear the saved minimum amount threshold; that threshold does not establish a clinical fatigue effect.

Folate · 667 mcg DFEVitamin B12 · 100 mcg
B vitamins and folate provide nutritional availability for normal metabolism and blood formation when intake falls short. Their high amounts do not establish improved energy or extra benefit in adequately nourished adults. B6 is declared at 100 mg per serving, triggering the supplied long-term sensory-neuropathy concern. The folate DFE declaration is not added to its separately retained folic-acid mass.
How this product is rated for Everyday Health
Ingredient fit85
Folate provides the leading connection in the saved general-health findings.
Goal fit
Folate provides the leading connection in the saved general-health findings.
Dose adequacy
Most included B vitamins reach their saved comparisons; larger amounts do not establish greater benefit.
Pathways80
Energy metabolism cofactors is the strongest route in the saved findings.
Depth
Energy metabolism cofactors is the strongest route in the saved findings.
Breadth
Two routes receive substantial contributions in the saved findings.
Evidence82
Folate leads the evidence finding; its nutritional contribution does not establish extra outcomes above adequate intake.
Evidence strength
Folate leads the evidence finding; its nutritional contribution does not establish extra outcomes above adequate intake.
Studied preparation
The included declarations receive a positive preparation finding; named forms do not establish superior functional effects.
Formulation logic93
B6 at 100 mg per serving triggers the supplied long-term sensory-neuropathy concern.
Partner coverage
The included ingredients work independently or have their required partner.
Conflicts
B6 at 100 mg per serving triggers the supplied long-term sensory-neuropathy concern.
Effective doses
All included ingredients meet the saved minimum amount comparison; that threshold does not establish clinical effectiveness.

B vitamins help the body carry out normal energy-yielding metabolism: thiamin supports carbohydrate processing, riboflavin and niacin provide coenzymes, and B6 participates in protein and glycogen metabolism. These essential functions do not show that extra vitamins raise resting or daily calorie expenditure when intake is adequate. The declared amounts therefore do not establish a faster metabolic rate or sustained weight loss.
How this product is rated for Metabolism Support
Ingredient fit79
B vitamins provide the main connection. The included amounts provide only a partial match to reference exposures; this does not establish effective doses for raising calorie expenditure.
Goal fit
B vitamins provide the main metabolic connection, within a formula also associated with other health goals.
Dose adequacy
The included amounts provide only a partial match to reference exposures; this does not establish effective doses for raising calorie expenditure.
Pathways0
No direct thermogenic pathway was identified beyond the ordinary nutrient roles. No pathway reached the coverage threshold, so direct support for a metabolism boost remains limited.
Depth
No direct thermogenic pathway was identified beyond the ordinary nutrient roles.
Breadth
No pathway reached the coverage threshold, so direct support for a metabolism boost remains limited.
Evidence100
Thiamin leads the saved comparison, but normal carbohydrate metabolism does not establish increased calorie expenditure from extra thiamin.
Evidence strength
Thiamin leads the saved comparison, but normal carbohydrate metabolism does not establish increased calorie expenditure from extra thiamin.
Studied preparation
The included preparations match the saved comparison, which does not establish a measured increase in energy expenditure.
Formulation logic100
No missing required partner or configured conflict was identified. The included amounts meet the minimum exposure comparison without demonstrating an extra benefit from combining them.
Partner coverage
No missing required partner was identified; the combination does not establish an additional metabolic-rate effect.
Conflicts
No configured ingredient conflict was identified in the supplied facts.
Effective doses
The included ingredients meet the minimum exposure comparison, which does not establish an effective thermogenic or weight-loss dose.
