How it works
Build -- cofactor for prolyl and lysyl hydroxylase enzymes required to cross-link collagen fibers
Maintain -- donates electrons as a water-soluble antioxidant and helps regenerate oxidized vitamin E
Transform -- cofactor for carnitine biosynthesis, supporting fatty-acid transport into mitochondria, and for dopamine beta-hydroxylase in catecholamine synthesis
Exchange -- converts dietary nonheme iron to a more absorbable form in the gut, enhancing uptake
Form matters
The same nutrient can be made in very different forms -- and a study done on one form does not automatically apply to another. Methylcobalamin is not cyanocobalamin; magnesium glycinate is not magnesium oxide; a whole-food extract is not the synthetic isolate that was studied. Two things decide whether what is in the bottle behaves like the research: the exact form, and independent lab verification (a Certificate of Analysis) that the form and dose on the label are truly what is inside. Without a COA, you are trusting a label, not the science.
On Vitamin C specifically: Ascorbic acid and mineral-ascorbate/'buffered' forms deliver the same active molecule; liposomal and polyphenol-bound forms are marketed for absorption but the comparative human bioavailability evidence is thinner than the base vitamin's own research base.
Across your systems
Vitamin C sits at the crossroads of collagen synthesis, iron absorption, and antioxidant recycling -- it is a required cofactor for the enzymes that stabilize collagen's triple helix, it converts poorly-absorbed non-heme iron into a form the gut takes up more readily, and it regenerates spent vitamin E at the membrane surface.
