As a result, you can also develop symptoms of iron deficiency, including pale skin, fatigue and brittle nails that split.Foods that are high in vitamin A include carrots, liver, spinach, cantaloupe and fortified foods, including milk and breakfast cereals.f you have splitting and peeling nails that aren't due to environmental causes, consult your physician for the correct diagnosis before treating them with a vitamin supplement.
Nail splitting may also be caused by nail cosmetics (hardeners, polish, polish removers/solvents), nail procedures, and occupational exposure to various chemicals (alkalis, acids, cement, solvents, thioglycolates, salt, sugar solutions). Injury (trauma) may also play a role in the development of brittle nails.
