As we get older, nails can become thinner, brittle, or slow-growing due to changes in nutrition and hormones. The good news is that the right foods can significantly improve nail strength and appearance.
Here are some of the most effective nutrients—and the foods rich in them—that help strengthen nails after 40:
🥚 Protein (the building block of nails)
Nails are made of keratin, a protein—so low protein intake can lead to weak, peeling nails.
