Strong, healthy, and shiny nails that are free from breakage and splitting start with proper nutrition. If you’re dealing with brittle nails, ridges, or other imperfections, your body may be lacking certain essential vitamins and minerals. The following nutrient-rich foods help nourish your nails from within, giving you the strong and smooth nails you desire.
1. Dark Leafy Greens: Spinach, Kale, and Broccoli
Dark leafy greens such as spinach, kale, and broccoli are packed with iron, calcium, and vitamins A and C. Vitamin C enhances iron absorption, supports collagen production, and improves nail health. Iron is crucial for strong nails, preventing them from becoming brittle and prone to breakage.

2. Sweet Potatoes: Vitamin A for Strong Nails
Sweet potatoes are rich in beta-carotene, a precursor to vitamin A, which helps the body produce keratin, an essential component of nails. A deficiency in vitamin A can lead to weak, brittle, and misshapen nails. Sweet potatoes also provide vitamin C, B6, manganese, and iron for comprehensive nail nourishment.
3. Eggs: Biotin and Protein Powerhouse
Eggs are excellent for nail health due to their high protein content and biotin, a vital B-vitamin involved in keratin production. Biotin helps prevent nail weakness and breakage. For optimal biotin absorption, consume fully cooked eggs instead of raw ones.

Salmon is not only good for your heart but also benefits your nails. It’s rich in omega-3 fatty acids, protein, and vitamin D, which moisturize and improve nail elasticity. Omega-3 helps prevent dry, brittle nails, keeping them supple and strong.
