Product analysis
Fully Active B Complex with Quatrefolic can help fill B-vitamin gaps that affect normal energy use, nerve function and blood formation. Several mixtures lack proportion details, making the full formula less straightforward to compare.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality74
Several vitamins use clearly identified forms, including active folate and a phosphate form of B2. Biotin’s exact form is unspecified, and selected vitamin forms do not by themselves establish extra benefits.
Ingredient Transparency77
Amounts are listed and most forms are identified. Three mixture breakdowns and biotin’s exact form are missing, limiting the detail behind the formula.
Value For Money58
Folate and B6 offer good value, with a favorable B2 serving cost. Niacin and B5 look less economical, so the combination’s value depends on which nutrients you need.
Customer Satisfaction91
Ratings are favorable across a very large review pool. That gives a broad picture of buyer satisfaction without proving improved energy or cognition.
Product Focus62
The clearest role is filling nutrient gaps that can affect energy, nerves and blood formation. High amounts and active forms do not establish better focus, mood or energy when intake is already adequate.

Vitamin B5 · 100 mgRiboflavin · 75 mgThiamin · 60 mgVitamin B12 · 1000 mcg
The B vitamins support normal metabolism and can address fatigue associated with nutritional deficiency; B12 and B6 are also relevant to deficiency-related anemia. Vitamin C contributes to filling a low-intake gap. Folate is declared in plain mcg, so its required DFE amount remains unresolved. The high amounts and selected forms do not establish extra energy when nutritional needs are already met.
How this product is rated for Energy
Ingredient fit86
Most amounts receive full recognition, vitamin C receives partial recognition, and folate lacks the required DFE amount.
Goal fit
Vitamin B12 contributes to the product's nutritional connection to fatigue; broader product uses also influence its focus.
Dose adequacy
Most amounts receive full recognition, vitamin C receives partial recognition, and folate lacks the required DFE amount.
Pathways0
The saved findings recognize no coverage of the specified alertness, exercise or fatigue pathways.
Depth
No specific route receives coverage in the saved findings, despite the nutrients' normal physiological roles.
Breadth
None of the specified routes reaches the coverage threshold.
Evidence81
Vitamin B12 leads the saved evidence finding. The relevant evidence concerns nutritional deficiency, rather than additional energy when needs are met.
Evidence strength
Vitamin B12 provides the strongest recognized evidence, with fatigue benefits limited by the relevant nutritional or population context.
Studied preparation
The recognized ingredients pass the preparation check; this does not independently prove fatigue relief from this finished product.
Formulation logic97
No unmet partner requirement or configured conflict was found. Folate remains below the amount requirement because DFE is unresolved.
Partner coverage
The recognized ingredients have no unmet partner requirement in the supplied findings.
Conflicts
No configured ingredient conflict was identified; this check does not cover every possible interaction.
Effective doses
Seven recognized ingredients meet the amount threshold; folate does not because its required DFE amount is unresolved.

B vitamins help the body use carbohydrates, fats and protein through their coenzyme roles. Supplying more than adequate intake does not establish a rise in resting or daily energy expenditure. The formula's recognized amounts reflect a comparison framework rather than proof that high B-vitamin amounts accelerate metabolism. The mixed phosphorylated and ordinary vitamin forms do not establish additional heat production.
How this product is rated for Metabolism Support
Ingredient fit83
B vitamins supply the credited contributions, though linked to several goals.
Goal fit
B vitamins supply the credited contributions, though linked to several goals.
Dose adequacy
Amounts receive substantial recognition overall; reaching a benchmark does not establish faster metabolism.
Pathways0
The saved findings show no coverage of the configured metabolic-rate pathways, despite recognizing the nutrients' amounts.
Depth
None of the configured metabolic-rate pathways receives coverage from the credited nutrients.
Breadth
No area reaches the saved threshold for substantial coverage.
Evidence100
Thiamin leads the saved evidence finding, and the credited preparations are recognized. Normal nutrient or cellular roles still differ from measured whole-body energy expenditure.
Evidence strength
Thiamin leads the saved evidence finding; the clinical scope and outcome limitations described above still apply.
Studied preparation
The saved findings recognize the credited preparations; this does not establish a sustained metabolism or fat-loss effect.
Formulation logic100
No unmet partner requirement or configured conflict was found. All credited ingredients clear the amount threshold used for inclusion.
Partner coverage
Each credited ingredient works independently or has its required partner.
Conflicts
No configured conflict was matched among the evaluated combinations.
Effective doses
All credited ingredients clear the inclusion threshold; this is not proof of an effective energy-expenditure dose.
