Biotin supports the keratin structure, helping nails grow thicker and reducing the likelihood of ridging due to fragility.
The Importance of Iron for Nail Integrity
Iron deficiency can lead to various nail issues, including thin nails and, in severe cases, spoon-shaped nails (koilonychia). While vertical ridges alone do not necessarily indicate iron deficiency, persistent weakness or fatigue alongside nail changes may warrant a discussion with a healthcare provider.
Iron-rich foods to consider include:
- Lean red meat
- Chicken thighs
- Lentils
- Chickpeas
- Pumpkin seeds
- Dark leafy greens
Pairing plant-based iron sources with vitamin C-rich foods, such as citrus fruits or bell peppers, can enhance iron absorption.
Zinc: A Key Player in Nail Growth and Repair
Zinc is crucial for cell growth and repair, and a deficiency can lead to nail abnormalities, including ridges or white spots. To ensure adequate zinc intake, include foods like:
- Oysters
- Beef
- Cashews
- Sunflower seeds
- Whole grains
Since the body does not store zinc efficiently, consistent intake is essential for maintaining nail health.
