Those mysterious bruises aren’t always random accidents or signs you’re “just sensitive.” A bruise is blood leaking under the skin after tiny vessels break, often from a bump you barely noticed. But when they appear often, in odd places, or take too long to fade, they can signal deeper problems—sometimes starting with something as simple, and as serious, as a vitamin deficiency.
Low levels of vitamin C can weaken collagen, the protein that keeps blood vessels resilient. Fragile vessels break more easily, leaving you speckled with marks that seem to appear from nowhere. A lack of vitamin K can slow clotting and weaken capillary walls, turning minor trauma into dramatic discoloration. While many bruises are harmless, frequent or unexplained ones deserve attention. Nourishing your body, tracking changes, and speaking with your doctor can turn those silent warnings into answers—and relief.
