General Ingredient Research — not an evaluation of this product
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.
strongSupports immune functionZinc 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.
strongSupports wound healingEssential for skin integrity and wound repair processes.
strongSupports bone healthPrimary structural component of bones. Adequate lifelong intake, combined with vitamin D, helps prevent osteoporosis — supported by extensive clinical evidence.
strongSupports muscle functionEssential for muscle contraction through calcium signaling.
moderateSupports sleep qualityMay improve sleep quality, especially in older adults and those with low magnesium status.
strongSupports bone health60% of body magnesium is stored in bone. Essential for bone mineralization.
moderateSupports muscle recoveryMay reduce muscle cramps and support post-exercise recovery.
strongPrevents neural tube defectsAdequate folate intake before and during early pregnancy reduces risk of neural tube defects. This is one of the most well-established findings in nutrition.
strongSupports DNA synthesisEssential cofactor for nucleotide synthesis and cell division.
strongSupports red blood cell formationEssential for red blood cell formation. Deficiency causes megaloblastic anemia, confirmed by decades of clinical evidence.
strongSupports neurological functionInvolved in myelin synthesis and nerve function. Adequate B12 status supports neurological health, particularly in older adults and vegans.
moderateSupports energy metabolismCofactor in energy production pathways, but supplementation only helps if deficient.
moderateSupports brain functionInvolved in neurotransmitter synthesis including serotonin and dopamine. Cofactor for over 100 enzyme reactions.
strongMay reduce homocysteineB6 is a cofactor in the transsulfuration pathway, converting homocysteine to cysteine. This is a separate pathway from the B12/folate remethylation route.
strongSupports immune functionSupports immune cell function. Regular supplementation may modestly reduce cold duration, but does not prevent colds.
strongAntioxidant protectionPotent water-soluble antioxidant that protects cells from oxidative damage.
strongSupports collagen synthesisEssential cofactor for enzymes involved in collagen production.
strongAntioxidant protectionProtects polyunsaturated fatty acids in cell membranes from oxidation.
moderateSupports skin healthMay help protect skin from UV damage when combined with vitamin C.
weakSupports hair and nail growthLimited evidence. May help in cases of biotin deficiency but most people get adequate amounts from diet.
strongSupports metabolic functionEssential cofactor for carboxylases involved in gluconeogenesis, fatty acid synthesis, and amino acid catabolism.
moderateSupports cholesterol levelsAt pharmacological doses (1500-3000mg), niacin may improve HDL cholesterol. This effect is dose-dependent and not expected at typical supplement doses.
strongSupports energy metabolismEssential coenzyme (NAD/NADP) in hundreds of metabolic reactions.
strongSupports energy metabolismEssential cofactor for pyruvate dehydrogenase and other enzymes in carbohydrate metabolism.
strongSupports energy metabolismEssential cofactor for pyruvate dehydrogenase and other enzymes in carbohydrate metabolism.
moderateSupports cholesterol levelsAt pharmacological doses (1500-3000mg), niacin may improve HDL cholesterol. This effect is dose-dependent and not expected at typical supplement doses.
strongSupports energy metabolismEssential coenzyme (NAD/NADP) in hundreds of metabolic reactions.
moderateMay help prevent migrainesAt 400mg/day (far above RDA of 1.3mg), riboflavin may reduce migraine frequency. Effect is dose-dependent and not expected at typical supplement doses.
