The Best Foods for Healthier Nails
1. Biotin-Rich Foods – The Nail Growth Superstar
Biotin (vitamin B7) is perhaps the most well-researched nutrient for nail health. Studies show it can increase nail thickness and reduce splitting.

Broccoli

Salmon
How much: Aim for at least one biotin-rich food daily.
2. Iron – For Strength and Color

Tofu
Pro tip: Pair iron-rich foods with vitamin C (citrus, bell peppers) to boost absorption.
