Do you have brittle or broken nails? What do you think are the reasons for brittle nails? Very often we do not give importance to this part of the body.

The nails grow on the fingertips and face the aggressions of the outside world. They scratch surfaces and, very often, during this action, they break, bend or scratch.

But why do they break? What is the reason for brittle nails? Often due to the absence of glycine (an amino acid responsible for regenerating collagen production).

Glycine deficiency causes fragility and abnormal nail growth. Hence, collagen production is indispensable for their growth.

At the same time, there are cases where brittle nails are caused by a wound or fungal infection, such as nail fungus or onychomycosis.
