Beyond Orange Juice
Ask someone what Vitamin C does and they will almost certainly say: “It helps with colds.” They are not wrong — but they are barely scratching the surface. Ascorbic acid is one of the most structurally versatile and physiologically essential molecules in the human body. It is a master antioxidant, an enzyme co-factor critical to collagen synthesis, a key player in neurotransmitter production, a modulator of immune function, and an enhancer of iron absorption. Scurvy — the devastating disease caused by Vitamin C deficiency — was once the leading cause of death among sailors not because it weakened their immune systems, but because without ascorbic acid, their bodies could not hold themselves together at a structural level [1].
Yet despite its vital importance, Vitamin C remains chronically underappreciated in modern supplementation. Many people assume that a daily multivitamin or a glass of orange juice covers their needs. The evidence suggests otherwise — both in terms of how much we actually need and how effectively standard supplements deliver it. This article examines what Vitamin C really does, why most people are getting less than they think, and what the science says about optimising your intake for genuine, measurable benefit.
Vitamin C is an essential co-factor for prolyl hydroxylase and lysyl hydroxylase, the enzymes responsible for stabilising the triple-helix structure of collagen [2]. Collagen is the most abundant protein in the human body, forming the scaffolding of skin, tendons, ligaments, blood vessel walls, bone matrix, and cartilage. Without adequate Vitamin C, collagen is produced in a structurally defective form that cannot maintain tissue integrity — hence the bleeding gums, fragile skin, and wound healing failure that characterise scurvy [1].
