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 vision healthEssential for rhodopsin production in the retina. Deficiency causes night blindness — one of the earliest recognized nutritional deficiencies.
strongSupports immune functionCritical role in maintaining mucosal barriers and immune cell function.
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.
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.
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.
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 iron levelsIron supplementation is used to address iron deficiency. Should be taken under medical supervision as excess iron can be harmful.
strongSupports energy levelsIron is essential for oxygen transport and cellular energy production.
