Vitamin B5 · 50 mgRiboflavin · 50 mgThiamin · 50 mgVitamin B12 · 50 mcg
Riboflavin, B6, folate, niacin and pantothenic acid can help fill dietary gaps whose deficiencies cause tiredness or fatigue. These nutritional contributions do not establish a stimulant effect or added energy in adequately nourished adults. The high B-vitamin amounts do not establish greater benefit than nutritional adequacy.
How this product is rated for Energy
Ingredient fit90
The relevant B vitamins contribute within a broader formula containing ingredients outside the supported energy roles. The counted ingredients supply differing portions of their comparison amounts, limiting some contributions.
Goal fit
The relevant B vitamins contribute within a broader formula containing ingredients outside the supported energy roles.
Dose adequacy
The counted ingredients supply differing portions of their comparison amounts, limiting some contributions.
Pathways0
No direct alertness or exercise-energy area receives a contribution; the relevant nutrient contributions remain conditional on low intake. No direct energy area reaches the supplied breadth comparison.

B vitamins help normal energy-yielding metabolism, but extra intake has not been shown here to raise whole-body calorie expenditure above adequate nutrition. Their declared amounts receive saved contributions without establishing a direct thermogenic effect or sustained weight loss.
How this product is rated for Metabolism Support
Ingredient fit83
The saved findings count nutrient amounts, principally B vitamins. Normal energy metabolism does not establish an increase in calorie expenditure.
Goal fit
Other actives broaden the formula beyond this goal, reducing its focus.
Dose adequacy
The known amounts provide partial support in the saved comparison, without establishing a proven thermogenic dose.
Pathways0
No configured thermogenic function receives a contribution from these ingredients.
Depth
No configured thermogenic function receives a contribution.
Breadth
No function reaches the saved breadth threshold.
Evidence100
Vitamin B1 (Thiamin) is the strongest saved evidence contributor. The supplied scientific context does not establish a routine increase in calorie expenditure.
Evidence strength
Vitamin B1 (Thiamin) supplies the strongest saved evidence contribution; this does not override limitations in the direct energy-expenditure findings.
Studied preparation
The counted amounts match preparations accepted in the saved comparison.
Formulation logic100
The counted ingredients can contribute independently and no configured conflict is found. Their known amounts pass the saved minimum.
Partner coverage
The counted ingredients can contribute independently or have the required partner.
Conflicts
No configured ingredient conflict was identified in the supplied facts.
Effective doses
The counted amounts pass the saved minimum, which does not establish a proven increase in energy expenditure.
