Have you noticed lines on your nails recently? While often harmless, these marks can sometimes indicate health issues or nutrient deficiencies.

**1. Aging**
As you grow older, vertical lines on your nails may appear more prominent. These lines, from the base to the tip, are typically not a concern.

**2. Nutrient Deficiencies**
Lack of certain nutrients can affect nail health. For example, “low levels of Vitamin B12 can change your nails’ color and texture.” Dehydration weakens nails, leading to lines. Similarly, iron deficiency may cause spoon-shaped nails with vertical ridges.

**3. Injury**
Fingernail injuries, such as crushing or picking, can result in lines. These injuries harm the skin under the nail and disrupt growth.

**4. Skin Conditions**
Skin disorders like psoriasis or eczema may cause ridges, particularly around the cuticles. These ridges reflect changes in the skin near the nails.

**5. Circulation Issues**
Poor blood circulation, linked to conditions like peripheral artery disease, can reduce blood flow to your nails, affecting their appearance.

In general, lines on your nails are harmless signs of aging. However, if you notice other changes such as “color differences or thickness variations,” consult a doctor. Maintaining proper nutrition, hydration, and nail care can help keep them healthy.
