Biotin ( Vitamin B7) Deficiency Biotin plays a key role in maintaining healthy nails, hair, and skin. A lack
of biotin can cause nails to become thin, brittle, and prone to splitting.
Foods rich in biotin include:
Eggs Almonds Cauliflower Cheese Mushrooms Sweet potatoes
Spinach Consistently including these foods in your diet may help strengthen nails over time.
Iron Deficiency Iron is essential for producing hemoglobin, which delivers oxygen to cells throughout the body—including those responsible for nail growth. Low iron levels can lead to brittle, fragile, or unusually shaped nails.
Iron-rich foods to consider:
Spinach and other leafy greens Red meat Lentils and beans Fortified cereals If iron deficiency is suspected, it’s important to consult a healthcare professional before taking supplements.
Insufficient Protein Intake Because nails are composed of keratin, inadequate protein intake can weaken their structure, slow growth, and increase breakage.
