Essential nutrients for keeping nails healthy are: Protein: Nails are mostly composed of a protein named keratin. Not having enough protein can make it hard for your body to create strong and healthy nails. Vitamin B12: Not having enough B12 can make your nails change color and texture. Low levels of iron can cause vertical lines on nails and sometimes nails that look like spoons. 3. Dehydration is when your body loses too much water.

Not drinking enough water can impact your whole body, including your nails. If you don’t drink enough water, your nails can become weak and have lines on them. It’s important to drink enough water to keep your nails and skin healthy.

4. Injury to a fingernail. Injuries like crushing or constantly picking at your nails can create lines on them. These injuries can harm the skin under the nail and affect how the nail grows.Skin Conditions Some skin problems, like psoriasis or eczema, can lead to changes in the nails, like ridges, especially around the cuticles or the skin near the nail.

6. Heart and blood vessel illnesses. Bad circulation can reduce the amount of blood reaching your nails, which can impact how they grow and look. Health issues like peripheral arterial disease or other heart problems can show symptoms in the nails. Final thoughts Lines going up and down on your nails are typically a harmless indication of getting older. If you see any other changes in your nails, such as color differences, thickness variations, or if there are other symptoms along with the ridges, it’s a good idea to see a doctor. Eating well, drinking enough water, and being careful not to hurt your nails can keep them healthy and looking good. Keep in mind that your nails can show how healthy you are, so it’s important to take care of them.
