3. Support Nails With Nutrition
Focus on foods rich in:
Biotin: eggs, nuts, sweet potatoes
Iron: leafy greens, beans, lean meats
Zinc: seeds, seafood
Protein: nails are made of keratin
If you suspect a deficiency, talk to your doctor before starting supplements.
4. Choose Nail Products Wisely
Avoid harsh nail polish removers with acetone
Use strengthening base coats sparingly
Give nails regular “polish-free” breaks
The Bottom Line
For most people over 40, vertical ridges on fingernails are a normal sign of aging, much like fine lines on the skin. They usually reflect slower cell turnover, mild dehydration, or subtle nutrient changes — not disease.
Think of your nails as a quiet messenger. When cared for properly, they can remain strong, healthy, and attractive well into later years.
