A Nutrition Guide for Healthier Nails
Your nails are more than just a canvas for polish—they’re windows into your overall health. Brittle, peeling, ridged, or slow-growing nails can often be traced back to nutritional gaps. While genetics and external factors (like frequent hand-washing, harsh chemicals, or gel manicures) play a role, what you eat has a profound impact on nail strength, growth, and appearance.
Here’s a science-backed guide to the key nutrients your nails crave—and how to get them.
💅 Top 6 Nutrients for Strong, Healthy Nails
1. Biotin (Vitamin B7)
Why it matters: Biotin is essential for the production of keratin—the tough, fibrous protein that makes up your nails, hair, and skin. It helps improve nail infrastructure, reducing brittleness and splitting.
- Deficiency signs: Thin, splitting, or brittle nails; hair loss; scaly red rash around eyes/nose/mouth.
- Daily need: 30 mcg for most adults.
- Food sources: Cooked eggs (yolk), almonds, sweet potatoes, salmon, avocado, nuts, seeds, and whole grains.
- 💡 Note: Studies show biotin supplements can improve nail thickness and reduce splitting in people with brittle nails—but results are most significant if you are actually deficient. Always consult a doctor before starting high-dose supplements, as biotin can interfere with certain lab tests.
