Can lack of zinc cause nails to split?

There are many health concerns that can cause nails to split, peel, or be brittle, and zinc deficiency is definitely one of them. Other factors may include iron or vitamin A deficiency, exposure to toxins in nail polish remover, soaps and detergents, and even excessive exposure to water. Keeping your nails and cuticle beds moisturized, wearing gloves while washing dishes, cleaning, or using harsh chemicals, using natural detergents, cleaning products, moisturizers, and especially nail products like nail polish and polish remover will go a long way toward improving your nail health and preventing splitting. A biotin supplement can help as well. Make sure to see your doctor or other healthcare practitioner to get to the true root of the cause of your nail splitting before starting any additional supplementation.
