The half-moons at the base of your fingernails are also known as lunulas, which is Latin for 'little moon'. While some people believe that missing half-moons are a sign of vitamin deficiency, this is a myth. In fact, the size and shape of your nail matrix (and the half-moons that accompany them) are determined at birth. However, an absent lunula can sometimes indicate anaemia, malnutrition, or depression.

What You'll Learn

The connection between missing moons and health issues
The rounded shadows at the base of your nails are called fingernail moons, or lunula in Latin. The place where each nail begins growing is known as the matrix, and the lunula is part of this.
The size and shape of the nail matrix are determined at birth and are what determines nail quality to a large degree. So, if you can't see your half-moons, it doesn't necessarily mean that they don't exist or that something is wrong with your health. They may be hidden under your skin, and you may only be able to see them on your thumbs, or not at all.
However, an absent lunula can sometimes indicate anemia, malnutrition, and depression. If you are experiencing any of these symptoms along with an absence of lunula, it is recommended that you make an appointment with your doctor.
Azure lunula is a phenomenon where the moons of the fingernails take on a blue discolouration.

The role of the nail matrix
The nail matrix is the place where each nail begins growing. It is an oval-like structure that produces the actual nail plate, and is also referred to as the nail root. The nail matrix is where new cells are made that will make up the nail. The lunula, or half-moon, is part of the nail matrix.
The size and shape of the nail matrix determine nail quality to a large degree. When someone can’t visualise their half-moon on their thumbnail, it generally means they have relatively small matrixes and are more predisposed to have thin, small nails. However, just because you can’t see your half-moons doesn’t mean that they don’t exist. They may be hidden under your skin.
While an absent lunula can indicate anemia, malnutrition, and depression, Dr. Stern says that our nail matrixes (and the half moons that accompany them) are determined at birth and are not influenced by the vitamins we consume.
