Clinically Studied Benefits (with research)
• Immune support — Vitamin C supports barrier integrity and leukocyte function; regular use helps shorten common-cold duration. (NIH/PMC — Carr & Maggini, Nutrients 2017)
• Common-cold duration (adjunct) — Human RCT syntheses show reduced cold duration/severity with regular vitamin C. (NIH/PMC — Hemilä, Nutrients 2017)
• Antioxidant protection — Scavenges reactive oxygen species and regenerates other antioxidants; lowers oxidative stress markers in humans. (NIH/PMC — Carr & Maggini, 2017)
• Collagen formation & skin — Essential cofactor for collagen hydroxylation; human data link sufficiency to dermal matrix and wound outcomes. (NIH/PMC — Carr & Maggini, 2017)
• Iron absorption — Enhances non-heme iron uptake by reducing Fe3+ to Fe2+ and forming absorbable complexes. (NIH/PMC — Lane & Richardson, 2014)
• Endothelial & cardiometabolic markers — Clinical evidence for improved endothelial-dependent vasodilation and select lipid/inflammation markers. (NIH/PMC — Carr & Maggini, 2017)
• Blood pressure (adjunct) — Meta-analytic RCT data show modest reductions, especially in hypertensive adults. (NIH/PMC — Juraschek et al., 2012)
• Wound healing support — Adequate vitamin C status is associated with improved tissue repair dynamics. (NIH/PMC — Carr & Maggini, 2017)
Additional Studies Showing Promising Benefits*
• Skin/photodamage (adjunct) — Oral vitamin C–containing regimens show signals for improved texture and reduced UV photodamage (heterogeneous dosing/formulas). (NIH/PMC — Cosmeceuticals Review, 2013)
