As we age, nails can become thinner, brittle, or slow-growing—but the right nutrients can make a noticeable difference. Here are the most effective foods to strengthen nails after 40, along with why they work:

Your nails are made of keratin, so protein is essential.
Best foods:

One of the most important nutrients for nail thickness and growth.

⚠️ Simple daily habit (very effective)
Try this combo daily:

It covers protein, biotin, and healthy fats in one go.
If you want, I can create a 7-day meal plan using Pakistani foods specifically to improve nails, hair, and skin together.
