Deficiencies in iron, B vitamins (biotin, B12), and zinc commonly affect toenails, causing brittleness, spooning (koilonychia), discoloration, or ridges; other issues like protein, calcium, vitamin C, and magnesium deficiencies can also impact nail health, leading to various changes from weakness to specific patterns, though severe systemic illnesses can also be underlying causes.
Low vitamin d can lead to brittle nails. It might be worth getting tested.
2 Nail changes in vitamin B12 deficiency present as hyperpigmentation of nails like bluish discoloration of nails, blue-black pigmentation with dark longitudinal streaks, and longitudinal and reticulate darkened streaks.
A magnesium deficiency can result in weak, flaky nails that are prone to breakage.
Koilonychia is when your nails have an indented shape, like a spoon. Often, spoon nails are a sign of iron deficiency. You're also more likely to have spoon nails if you have an autoimmune disease, such as lupus, or poor blood flow to your hands or feet.
Medium to dark vertical lines on your nails could indicate a Vitamin D and B12 deficiency. Short white lines or spots might point to zinc deficiency. Brittle nails that easily break could mean you're low in calcium and biotin.
Iron deficiency can weaken the nails, making them more prone to splitting, breaking, or becoming brittle. Pale or white nail beds: Normal toenail beds should be pink. In severe cases of IDA, the nail beds may appear pale or even white due to reduced blood flow and oxygenation.
Those little white spots on your fingernails can have several causes, one of which is a sign of zinc deficiency. If you also have any other low-zinc signs such as frequent infections, irritability, slow healing, hair loss, or skin rashes, then it may be time to considering supplementing your zinc.
What are the symptoms of iron-deficiency anemia?
When your body lacks calcium, your nails become thinner, weaker, and brittle. You may notice that they break easily and just don't look as healthy as they used to. Although nails and bones are made up of different substances, they're similar enough that poor nail health may be an early marker of bone density problems.
Look how strikingly pale the nails are. Normally, your nails have a pinkish color because of the tiny blood vessels that are in the tissue underneath your nail. But in liver disease, there are changes to that tissue which makes it difficult to see the tiny blood vessels and that's why the nails are so pale.
Tingling and numbness: One of the most common symptoms is a tingling, prickling or numb sensation in the hands or feet. This can happen if the vitamin deficiency causes damage to the myelin sheath, which is a protective layer that surrounds and protects nerve fibers.
Zinc deficiency can cause Beau's lines and white spots on your nails. Iron deficiency can cause vertical nail ridges and koilonychia (spoon nails). Spoon nails have a depression in the middle, like the center of your nail was scooped out. You may be able to hold a drop of water on your nail.
Psoriatic arthritis or lupus can make your toenails abnormally thick. They may even start separating from your nail bed. If you develop lupus, your nails may have spots. People with lupus often have excessively thick or rough nail folds and cuticles with hyperpigmentation.
Symptoms of vitamin B12 or folate deficiency anaemia
Keratin needs vitamin A, C, D, E, and B-complex. These vitamins keep nails hard, strong, and intact. Without them, the keratin dries out, tears, develops hang nails, and may be prone to fungal infections. You also need sufficient iron, calcium, zinc, and iodine.
Possibly. The term "pica" describes craving and chewing substances that have no nutritional value — such as ice, clay, soil or paper. Craving and chewing ice, known as pagophagia, is often associated with iron deficiency, with or without anemia, although the reason is unclear.
Occasionally, it can cause chest pain, a fast heartbeat and shortness of breath. Or it can cause you to crave non-food items like ice, dirt or paper. These are all signs of iron-deficiency anemia. The good news is that treatment can help iron-deficiency anemia.
Iron is depleted by blood loss (heavy periods, bleeding ulcers, surgery), increased demand (pregnancy, growth spurts, intense exercise), poor dietary intake, and conditions that hinder iron absorption (celiac disease, gastric bypass, some medications, or certain foods/drinks like tea/coffee/dairy with meals). Exercise can cause loss through sweating, red blood cell damage (hemolysis), and increased needs, while poor absorption is a major factor, even with good intake.
Patients with reduced plasma magnesium levels can develop soft, flaky nails that are inclined to break or split.

Here's a comprehensive guide to ten nail diseases and disorders that deserve a closer look.
Brittle or spoon-shaped nails
Brittle nails chip and crack easily. Spending a lot of time with your hands in water or using some nail polishes can lead to brittle nails, but brittle nails can also be a sign of iron deficiency. Another sign of iron deficiency is 'spoon-shaped nails'.
Common toenail abnormalities include discoloration, thickening, and detachment, often linked to underlying health issues. Conditions like anemia, diabetes, and autoimmune disorders can manifest as changes in nail appearance or texture.
Symptoms of iron-deficiency anemia may include:
