3. "White Spots Mean Calcium Deficiency"
The mysterious white spots on nails have long been associated with calcium deficiency, leading many to unnecessarily supplement their diets. In reality, these white spots, known as leukonychia, are usually caused by minor trauma to the nail matrix—the area where nails grow. This trauma can occur weeks before the spot appears and is often so minor that you don’t even remember it happening. Common causes include bumping your finger, aggressive nail art, or pressure from tight shoes (for toenails). While dietary deficiencies can affect nail health, they typically cause more generalized changes rather than isolated spots. Understanding the true cause of these white spots is essential for proper nail care and overall health management. If you notice persistent or widespread nail changes, it’s best to consult a healthcare professional, as these could indicate underlying health issues. Many people who believe they have a calcium deficiency end up taking unnecessary supplements, which can have adverse effects if taken in excess. A balanced diet rich in various vitamins and minerals is more beneficial for overall nail health than focusing on specific nutrients. Dermatologists and nail experts agree that proper nail care practices, such as gentle handling and avoiding damage, are more effective than dietary supplements in preventing these white spots.
