This score evaluates label quality — dosage disclosure, transparency, cleanliness of inactive ingredients, and formula composition. It does not measure clinical efficacy, bioavailability, or third-party testing. Read full methodology
Same category, higher SupplementScore. Based on dosage transparency, label cleanliness, and formula quality.
The research summaries below are about the ingredients in general, drawn from published studies that often use different doses, forms, and populations than this product. A "strong" evidence rating for an ingredient does not mean this product will produce that effect — studied doses may be significantly higher or lower than what is contained here. Always verify doses against the Supplement Facts table above.
Primary structural component of bones. Adequate lifelong intake, combined with vitamin D, helps prevent osteoporosis — supported by extensive clinical evidence.
Essential for muscle contraction through calcium signaling.
Adequate folate intake before and during early pregnancy reduces risk of neural tube defects. This is one of the most well-established findings in nutrition.
Essential cofactor for nucleotide synthesis and cell division.
Essential for red blood cell formation. Deficiency causes megaloblastic anemia, confirmed by decades of clinical evidence.
Involved in myelin synthesis and nerve function. Adequate B12 status supports neurological health, particularly in older adults and vegans.

Alternatives are selected from the same category (B Vitamins) with a higher overall score. This is not a recommendation — always verify ingredients and dosages match your needs.
Cofactor in energy production pathways, but supplementation only helps if deficient.
Involved in neurotransmitter synthesis including serotonin and dopamine. Cofactor for over 100 enzyme reactions.
B6 is a cofactor in the transsulfuration pathway, converting homocysteine to cysteine. This is a separate pathway from the B12/folate remethylation route.
At 400mg/day (far above RDA of 1.3mg), riboflavin may reduce migraine frequency. Effect is dose-dependent and not expected at typical supplement doses.
At pharmacological doses (1500-3000mg), niacin may improve HDL cholesterol. This effect is dose-dependent and not expected at typical supplement doses.
Essential coenzyme (NAD/NADP) in hundreds of metabolic reactions.
Limited evidence. May help in cases of biotin deficiency but most people get adequate amounts from diet.
Essential cofactor for carboxylases involved in gluconeogenesis, fatty acid synthesis, and amino acid catabolism.
Essential cofactor for pyruvate dehydrogenase and other enzymes in carbohydrate metabolism.
