Another reason these ridges become more noticeable with age is related to nutritional absorption. As we get older, the body may not absorb vitamins and minerals as effectively. This can lead to mild deficiencies in nutrients like:
-
Biotin (Vitamin B7): Helps strengthen keratin.
-
Iron: Essential for oxygenating cells, including those that form nail tissue.
-
Magnesium: Supports healthy cell function.
-
Zinc: Aids in tissue repair and growth.
If your diet lacks these nutrients—or if you have trouble absorbing them—your nails may become thinner, more brittle, and more prone to developing ridges or other surface changes.
When to Be Concerned
Although most vertical ridges are simply signs of aging, some nail changes may indicate underlying health conditions. If your nails also show signs such as:
-
Discoloration (yellow, brown, or blue tones)
-
Thickening or splitting
-
Pain, redness, or swelling around the nail
-
Rapid or sudden changes in nail texture
…it’s best to consult a doctor or dermatologist. In rare cases, vertical ridges and other nail irregularities can be linked to thyroid disorders, poor circulation, rheumatoid arthritis, or even systemic infections.
