I had no idea! This resonates so much with me.

Strong, healthy nails often go unnoticed, but they’re powerful indicators of our overall well-being. When nails become prone to splitting, breaking, or developing unusual signs, they may be hinting at underlying health issues or nutrient deficiencies. Spotting these signs early not only improves nail appearance but can also guide us toward steps that enhance overall health.

In this guide, we’ll delve into possible reasons behind weak or brittle nails and explore what these symptoms may be saying about your body. From dietary influences and environmental factors to underlying health conditions, understanding these causes empowers you to make informed choices for your nutrition, lifestyle, and when to seek medical guidance. This comprehensive look at nail health aims to help you achieve not only beautiful nails but a healthier body.

1. Nutritional Deficiencies

Biotin Deficiency: Biotin, a B-vitamin, supports hair, skin, and nail health. A lack of biotin can make nails brittle and prone to splitting. Boost biotin intake with foods like eggs, almonds, cauliflower, cheese, mushrooms, sweet potatoes, and spinach.

Iron Deficiency: Iron is crucial for producing hemoglobin, which carries oxygen to cells that aid nail growth and strength. Low iron levels can result in brittle or unusually shaped nails. Foods rich in iron include spinach, red meat, lentils, and fortified cereals.

Low Protein Intake: Nails are primarily composed of keratin, a protein. Insufficient protein can weaken nails. Consider adding more lean meats, poultry, fish, legumes, and dairy to support nail structure.
