Introduction
Nail ridges—especially vertical lines running from the base to the tip—are common and often harmless. They can appear with age, dehydration, or minor nutritional gaps. While nail care products may help on the surface, what you eat plays a major role in nail strength and texture. A nutrient-rich diet can support smoother, healthier nails over time.
🥚 1. Protein for Strong Nail Structure
Nails are made primarily of keratin, a type of protein. Without enough protein in your diet, nails can become weak, brittle, or develop ridges.
Good sources include:
Eggs
Chicken or fish
