Healthy fingernails? - longitudinal lines
Are ridged fingernails related to a nutrition problem? The ridges I have in mind are vertical, extending from the bottom of the nail to the top.
Lines extending along the length of the nail are referred to as longitudinal lines. These lines are common changes, most of caused by normal aging.
Iron, Vitamin B-12, and zinc deficiencies and severe malnutrition can also cause nail changes. The changes you have described, however, are not suggestive of a significant nutritional disease.
