The Most Common Cause: Aging
One of the most frequent reasons for vertical ridges is simply aging.
As we get older, the body’s natural production of oils and moisture decreases. This can affect the nail matrix—the tissue responsible for nail growth—causing nails to become drier and more brittle. As a result, subtle ridges may form along the nail surface.
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.
