Low levels of essential nutrients such as biotin, iron, zinc or magnesium can weaken nails and ridges. Since metabolism and nutrient absorption may decrease with age, deficiencies become more likely after age 40.
In some cases, vertical ridges can indicate health problems such as poor circulation, thyroid imbalance, or even rheumatoid arthritis. If you notice other symptoms such as fatigue, brittle hair, or changes in skin texture, it is worth seeing a doctor. Shop for vitamins and supplements
When should you worry?
Although vertical ridges are generally benign, you should exercise caution if they present:
Changes in nail color (especially dark lines or streaks)
Nails that break, flake or thicken
Pain, swelling or inflammation around the nail
These could be signs of fungal infections, trauma, or in rare cases melanoma (a serious form of skin cancer that can appear under the nail).
