When it comes to weak and overall unsightly nails, biotin or vitamin B7 (and also other B vitamins) is crucial to make them strong and beautiful again. You’ll need biotin to maintain protein production. It will also help to get rid of cuticles.

Since our nails are mostly made of protein, you can take L-Lysine supplement to build healthy proteins and maintain healthy nails.

Iron makes the center of red blood cells, which are responsible for carrying oxygen to organs and every cell in the body — including nails. As oxygen is crucial for healthy nails, iron deficiency can cause vertical ridges in your nails or make them appear concave or “spoon” shaped.

Magnesium is a part of over 300 reactions in the body, including protein synthesis required for nail growth and strength.

There are a few medical conditions that can cause weak nails such as anemia (low blood count), thyroid issues (both hypo- and hyperthyroidism), and skin disorders such as psoriasis and lichen planus.

If you have ridges on your fingernails, it’s probably due to eczema or skin dryness. Nails are made by living skin cells in our fingers, so a skin disorder can make your body low in protein, zinc, calcium, or vitamin A, which can sometimes lead to ridges on the fingernails.

    Yes, this is true that biotin, or vitamin B7, is crucial to maintain protein production and can help strengthen weak or brittle nails. Since your nails are made of protein, L-Lysine supplements can be taken to help build healthy proteins and help maintain healthy nails. Apart from these tips, don’t cut or manipulate cuticles, use nail hardeners sparingly, moisturize the nail bed and the cuticle and limit professional manicures.
