I started taking iron supplements and eating more B12-rich foods. Within three months, my nails were unrecognizable—strong, smooth, and growing like weeds. No expensive treatments. No salon visits. Just nutrition.
Here’s what science says your nails truly need—and how to give it to them.
First, What Are Nails Made Of?
To understand what your nails need, you need to know what they’re made of.
Keratin: Your nails are composed primarily of hard keratin, a structural protein. Keratin provides strength, rigidity, and protection.
Water: About 10-15% of your nail plate is water. Too little water = brittle nails. Too much water (constant hand-washing, dishwashing without gloves) = soft, peeling nails.
