Vitamin C's roles across the layers of skin
This review describes how vitamin C accumulates in both the epidermis and dermis, where it supports collagen synthesis and helps provide antioxidant protection against UV-related photodamage, comparing evidence for dietary versus topical vitamin C on skin health.
ReviewVitamins across topical, procedural and systemic anti-aging strategies
This review describes how vitamins, including vitamin C, contribute to skin hydration, collagen biosynthesis and protection against oxidative damage across topical, cosmetic-procedure and systemic dietary-supplement approaches to skin aging.
ReviewA vitamin C derivative serum measurably increased dermal collagen
In a preclinical model and a randomized double-blind clinical trial, a stabilized vitamin C derivative serum upregulated dermal collagen production roughly four-fold versus a control moisturizer in an ex-vivo skin model, alongside visible improvements in photoaging and hyperpigmentation in the clinical portion.
Human RCTVitamin C supports collagen deposition in the vessel wall
In cultured vascular smooth muscle cells - the main cell type of the arterial wall - vitamin C markedly increased deposition of type V collagen and the formation of mature, striated collagen fibrils, highlighting its role as a cofactor for the enzymes that build and organize vascular collagen.
Lab studyVitamin C and E supplementation in a high cardiovascular-risk population
In a 12-month randomized, double-blind, placebo-controlled trial in adults with or at high risk of cardiovascular disease, a vitamin C and E combination was compared with an Ayurvedic herbal formulation and placebo for effects on vascular smooth-muscle and endothelial function, blood pressure and lipids.
Human RCTVitamin C and L-arginine improved blood vessel function in long COVID
This review of endothelial dysfunction in long COVID identifies vitamin C and L-arginine as among the few interventions shown in trials to improve flow-mediated dilation, a standard measure of blood vessel lining function, in this patient population.
ReviewLysyl hydroxylases govern collagen cross-linking
This review describes how lysyl hydroxylation of specific lysine residues, catalyzed by the PLOD enzyme family, is a key step controlling how collagen molecules cross-link and assemble in the extracellular matrix.
ReviewLysine-based collagen cross-links help determine bone quality
This review explains how lysyl-hydroxylase- and lysyl-oxidase-mediated collagen cross-links are a major determinant of bone's biomechanical properties, distinct from bone mineral density, and how alterations in this cross-linking pattern are linked to bone fragility.
ReviewLysyl oxidase builds collagen's covalent cross-links
This review describes how the enzyme lysyl oxidase acts on lysine residues to form the covalent cross-links between collagen triple helices in the extracellular matrix, a step that also generates reactive oxygen species as a byproduct.
ReviewProline biosynthesis is needed to maintain skin's collagen structure
Using both a rodent model and cultured skin fibroblasts, this study found that simulated microgravity suppressed the fibroblast enzyme PYCR1, lowering intracellular proline levels, reducing collagen production and thinning the dermis - restoring PYCR1 partially reversed the effect.
Animal studyA Krebs-cycle intermediate expands the proline pool for collagen production
In cultured human dermal fibroblasts and UVB-irradiated mice, alpha-ketoglutarate - a rate-limiting cofactor of prolyl-4-hydroxylase - increased the proline pool available for procollagen production and reduced UVB-induced wrinkle formation with long-term topical use.
Lab studyMapping where proline hydroxylation occurs across the proteome
This study developed a workflow combining chromatography and mass spectrometry to systematically map thousands of proline hydroxylation sites in human cells, including many outside of collagen, refining the tools available to study this key collagen-stabilizing modification.
Lab studyTaurine protected the heart in a sepsis model
In a mouse model of sepsis-induced cardiac injury, taurine treatment improved cardiac function and survival, reduced myocardial inflammation and oxidative stress, and preserved mitochondrial structure, an effect linked to inhibition of the NF-kB signaling pathway.
Animal studyTaurine supplementation supported neurons after induced ischemia
In a gerbil model of transient global cerebral ischemia, taurine given both before and after the ischemic event reduced neuronal death and glial activation in the hippocampus, alongside favorable changes in oxidative-stress and apoptosis markers.
Animal studyAn honest look at taurine for athletic performance in heat
This narrative review of nutritional strategies for football performed in hot conditions describes taurine as a promising ingredient for performance and recovery, but notes it is still supported by relatively few trials compared with more established strategies like hydration and electrolyte planning.
ReviewHow sodium, potassium and magnesium handling shapes blood pressure
This review of genetic disorders of renal tubular transport shows how the kidney's handling of sodium, potassium and magnesium is tightly coupled, and how small perturbations in this electrolyte handling can have disproportionate effects on systemic blood pressure.
ReviewAn electrolyte solution improved fluid balance versus placebo
In a randomized, placebo-controlled trial, healthy adults given a glycerol-electrolyte solution containing sodium, potassium, magnesium and calcium showed significantly better fluid balance and lower urine output over 8 hours than a matched placebo beverage.
Human RCTPotassium and magnesium as part of a multi-ionic approach to fluid balance
This review argues that chloride, potassium and magnesium status are tightly interconnected and should be assessed together, rather than focusing on sodium alone, when addressing fluid and electrolyte balance in clinical settings.
ReviewVitamin C is safe up to 2000 mg per day, with GI effects at high intakes
This safety review concluded that vitamin C supplements are safe for most adults at intakes up to 2000 mg per day, with the main adverse effect reported across clinical trials being occasional gastrointestinal upset or mild diarrhea from the osmotic effect of unabsorbed vitamin C at high doses.
ReviewHigh-dose vitamin C and kidney stone risk
This analysis highlights that high-dose vitamin C supplementation can increase urinary oxalate, a potential risk factor for oxalate kidney stones, and found that popular online information about vitamin C rarely mentioned this risk.
Observational studyKidney stone prevention guidance on vitamin C supplements
This nutrition review of kidney stone prevention strategies recommends that people prone to calcium oxalate stones limit vitamin C supplements, alongside other dietary measures such as adequate fluid intake and limiting oxalate-rich foods.
ReviewVitamin C reactivates the enzyme that hydroxylates collagen's proline residues
This study identified the first synthetic small-molecule activators of collagen prolyl 4-hydroxylase and confirmed vitamin C's established role in reducing the enzyme's iron center back to its active state after oxidative inactivation during catalysis.
Lab studyAscorbate's dual role in hydroxylation and protein folding
This review traces ascorbate's biochemical roles beyond antioxidant activity, describing its function as a cofactor for the prolyl and lysyl hydroxylases needed for collagen formation, and its involvement in oxidative protein folding more broadly.
ReviewVitamin C's history from scurvy cure to signaling molecule
This review traces vitamin C's discovery as the anti-scurvy factor - a deficiency caused mainly by impaired collagen-related hydroxylation - through to modern research on its lesser-known roles in cell signaling and gene expression.
