Warning Signs of Vitamin Deficiencies You Can Spot in the Mirror

47. Slow-Healing Abrasions and Vitamin K Deficiency

A subtle and often-missed indicator of compromised nutritional status is the unusually slow healing of small cuts, scratches, or papercuts—even weeks after the initial injury. This isn't about major wound healing, which involves zinc and C, but the slow resolution of surface abrasions. This can signal an inadequate intake of Vitamin K. Crucial for more than just major blood clotting, Vitamin K is vital for the proper production of proteins involved in tissue repair and regeneration. Without sufficient K, your body struggles to lay down the early-stage foundational scaffolding needed for skin repair, leading to the lingering appearance of small scabs or red marks. To support this vital process, regularly include green leafy vegetables like kale, spinach, and Swiss chard in your meals.

48. Burning Feet Sensation: Pantothenic Acid (B5) Deficiency

An often-overlooked and distinct symptom of a Pantothenic Acid (Vitamin B5) deficiency is a persistent, unpleasant "burning feet" syndrome, especially noticeable at night. This is a form of sensory peripheral neuropathy. Vitamin B5 is an absolutely essential cofactor for creating Coenzyme A (CoA), a molecule critical for energy metabolism and the synthesis of neurotransmitters like acetylcholine. Without sufficient B5, the delicate myelin sheath—the protective coating around nerve fibers—can become damaged, leading to misfiring nerve signals that the brain interprets as intense heat or a burning sensation in the extremities. Because B5 is so widespread in nature, this symptom is rare today but serves as a crucial warning that the body’s core neurological support is compromised. Ensure your diet includes ample amounts of liver, mushrooms, avocados, and whole grains to keep your peripheral nerves functioning smoothly.
