Much like wrinkles on the skin, vertical nail ridges are considered a normal age-related change and are generally not a cause for concern.
Nutritional Factors
In some cases, prominent nail ridges may be associated with nutritional deficiencies.
Nails require adequate amounts of vitamins, minerals, and protein to grow properly. Deficiencies in nutrients such as:
Iron
Vitamin B12
Folate
Magnesium
Zinc
can sometimes contribute to changes in nail texture and appearance.
Iron deficiency, in particular, may lead to brittle nails and other nail abnormalities. If nail changes are accompanied by fatigue, weakness, dizziness, or pale skin, it may be worth discussing nutrient testing with a healthcare professional.
