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.
Zinc is a cofactor for over 300 enzymes involved in immune cell development and function. Supplementation may reduce duration of common cold symptoms, particularly as lozenges. Essential for maintaining immune barrier integrity.
Essential for skin integrity and wound repair processes.
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 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.

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.
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.
Curcumin has anti-inflammatory properties in clinical studies, though bioavailability is low without enhanced formulations (piperine, liposomal, etc.).
Curcumin may reduce joint pain and inflammation in osteoarthritis. Effects depend on bioavailability — enhanced forms (BCM-95, Meriva, piperine) show better results than standard curcumin.
Some RCTs show improved skin hydration after 8-12 weeks at 2.5-10g/day of hydrolyzed collagen peptides. Results vary by collagen type and source.
May reduce joint pain in athletes and osteoarthritis patients, particularly type II collagen.
