Hi and thanks for query.

The black line might be splinter hemorrhages that is blood clot from small vessels like capillaries, they can result from trauma to nail bed. There are many other causes of such lines on nails including nutritional imbalances, fungal infection of nails, arthritis,and even infection of the heart valves, sometimes they are related to increasing age. I would suggest you should get it examined by your primary care physician to rule out anything serious. vitamins supplements can help if the cause is vitamin deficiency.
