The appearance of your nails and hair says a lot about your overall health. It is one of the initial signs that you might be facing health issues in near future. So, if your nails have become brittle, dry, flaky, broken or lacklustre, it is a sign that you are missing on some vital nutrients, especially vitamins and minerals that play an important role in nail growth and strength. On the other hand, if your fingernails are smooth with a pink glow, you are probably eating right.

Dry and cracked nails could indicate deficiency of calcium while lack of biotin could produce ridges along the nail bed. If you are not having sufficient Omega-3 in your diet, it may show up in the form of cracks in nails.
Dr Rinky Kapoor, Consultant Dermatologist, Cosmetic Dermatologist & Dermato-Surgeon, The Esthetic Clinics in an interview with HT Digital lists some vitamins and minerals that are important for nail growth.
Biotin or B7 is the most essential ingredient for nail health. It prevents brittleness and improves growth. You can find biotin in liver meat, egg yolk, dairy products, yeast, fish, avocado, sweet potatoes, nuts, and seeds.
Omega 3 fatty acids especially those found in fish oil adds strength to the nails and make it shiny. You will find it in walnuts, soy, and eggs also.
