5. Nutritional Deficiencies
Deficiencies in certain vitamins and minerals can affect nail health. Low iron levels are a common cause of brittle or splitting nails. Inadequate biotin intake may also contribute to weakness and breakage.
Foods that support nail health include:
- Iron-rich foods like spinach, beans, and lean meats
- Biotin-rich foods such as eggs, nuts, and whole grains
- Protein-rich foods that support keratin production
Before taking supplements, it is best to consult a healthcare provider.
6. Aging, Genetics, and Naturally Brittle Nails
As people age, nails naturally become thinner and more fragile. Genetics can also influence nail strength, making some individuals more prone to splitting than others.
Although aging and genetics cannot be changed, proper nail care can help reduce damage. Regular moisturizing, gentle filing, and avoiding harsh chemicals can improve nail resilience.
