What to Eat to Reduce Nail Ridges: A Nutrition Guide for Healthier Nails
- Eggs (fully cooked)
- Almonds and walnuts
- Sweet potatoes
- Spinach
- Salmon
Biotin supports keratin structure, helping nails grow thicker and less prone to ridging caused by fragility.
3. Iron: Preventing Weak or Grooved Nails
Iron deficiency can lead to thin nails and, in more severe cases, spoon-shaped nails (koilonychia). While vertical ridges alone don’t automatically mean iron deficiency, persistent weakness or fatigue alongside nail changes may be worth discussing with a healthcare provider.
Iron-rich foods include:
- Lean red meat
- Chicken thighs
- Lentils
- Chickpeas
- Pumpkin seeds
- Dark leafy greens
- Pair plant-based iron sources with vitamin C–rich foods like citrus fruits or bell peppers to improve absorption.
4. Zinc: Supporting Growth and Repair
Zinc plays an essential role in cell growth and repair. A deficiency may contribute to nail abnormalities, including ridges or white spots.
Include foods such as:
- Oysters
- Beef
- Cashews
- Sunflower seeds
- Whole grains
Because the body does not store zinc efficiently, consistent intake is important.
