Nails are made mainly of keratin, a strong protein produced in the nail matrix beneath the cuticle.
Because nails grow continuously, they can sometimes show signs of changes happening inside the body.
According to Mypersonaltrainer, ridges or grooves in the nails may indicate nutritional deficiencies or other health conditions.
However, nail changes should not be viewed as proof of a specific problem.

Different types of ridges
Doctors often look at the direction of nail ridges when assessing possible causes. Vertical ridges run from the base to the tip of the nail, while horizontal ridges run across the nail.
Vertical ridges, especially when combined with brittle nails, may be linked to low levels of B vitamins such as biotin, folate, or vitamin B12. Deficiencies in iron, calcium, or magnesium may also contribute to these changes.
Horizontal ridges, known as Beau's lines, may appear when nail growth has been temporarily disrupted.
They have been associated with zinc deficiency, severe protein deficiency, and conditions involving serious malnutrition.

Medical advice
Experts stress that ridged nails can have many causes.
Ageing, skin disorders, fungal infections, and hormonal conditions may produce similar changes.
For this reason, a medical evaluation is recommended before taking supplements. Blood tests can help determine whether a true deficiency exists.
Self treatment may delay diagnosis and, in some cases, lead to excessive intake of vitamins or minerals.
