4. Spoon-shaped nails
Take a look at your nails as they can also indicate a vitamin C deficiency. A concave or spoon shape is frequently related to vitamin C insufficiency. People who have spoon nails describe it as being able to hold a tiny drop of water on the top of their nail.
If this is your case, your nails could also become brittle and thin with red spots and vertical lines in the nail bed. These kinds of changes are more common on fingernails rather than toenails.
The medical term for this issue is splinter hemorrhage, and it’s usually caused by vitamin C deficiency. Keep in mind that these symptoms are also related to iron deficiency anemia. Talk to your doctor to find out if your spoon-shaped nails with red spots and vertical lines are a sign of vitamin C deficiency.
