Why are nails an important health indicator? The most important vitamins
Our nails are more than just decorative elements. They consist of keratin, a protein also found in hair and skin. Changes in the structure, color, or surface of the nails can indicate deficiencies, illnesses, or other health problems. Vitamin deficiency, in particular, can manifest on the nails in various ways.
The most important vitamins for healthy nails
Before we look at the specific signs, it's important to know which vitamins are essential for nail health:
Biotin (Vitamin B7): Promotes nail growth and stability.
Vitamin A: Supports cell regeneration and ensures healthy nail beds.
Vitamin C: Important for collagen formation, the basic structure for nails and skin.
Vitamin D: Regulates calcium balance, which also influences nail structure.
Iron: A mineral necessary for the oxygen supply to the nails.
Zinc: Supports cell division and nail growth.
Typical signs of vitamin deficiency on the nails
Here are the most common changes that can indicate a vitamin deficiency:
If your nails break easily, split, or peel off, this could indicate a deficiency in biotin or zinc. These vitamins are crucial for the stability and elasticity of the nails.
Tip: Pay attention to a diet rich in eggs, nuts, seeds, and whole-grain products to replenish your zinc and biotin reserves.
Vertical ridges or lines on the nails are often observed with iron deficiency or vitamin D deficiency. These deficiencies impair cell division and nail growth.
Yellow, white, or brownish discolorations can indicate a deficiency in vitamin C or iron. Vitamin C is important for collagen formation, which strengthens the nail plate.
Tip: Fresh fruits and vegetables, especially citrus fruits, bell peppers, and broccoli, promote vitamin intake and absorption. Remember the "ADEK" rule! Vitamins A, D, E, K are fat-soluble vitamins. Therefore, pay attention to when and with what you consume them. I recommend a balanced diet. Of course, I know it's always easier said than done. But sometimes small things can help, like the goal of eating one vegetable and one fruit a day. Yogurt is a great source of protein and nutrients. Therefore, feel free to also seek advice on dietary supplements at your trusted pharmacy. Furthermore, a check-up with a doctor is always advisable, especially if you need to take long-term medication.
What nails might look like with a vitamin B deficiency or iron deficiency?
Changes in nails are often quickly visible. "Women" immediately notice if something looks or feels different. One wonders: "where do these ridges, brittleness, or dryness suddenly come from?" These are usually clear indications that your body has a deficiency in certain nutrients and can help you to become aware of potential health problems early on.
What my nails might look like with a vitamin B deficiency:
Ridges and lines: With a deficiency in vitamin B, especially B7 (biotin) or B12, vertical ridges or lines may become visible on the nails. These lines run lengthwise along the nail and are often a sign of disturbed cell division and regeneration.
Brittleness and splitting: Nails that are brittle, fragile, or easily split due to vitamin B deficiency are common. This is because vitamin B plays an important role in the formation and stability of the nail structure.
Discoloration: Sometimes, nails can also appear pale or discolored with a vitamin B deficiency, which can indicate a general weakening of the nail plate.
Changes in the nail surface: The surface may appear uneven, rough, or dull, indicating disturbed cell formation in the nail bed.
Nails with iron deficiency:
Spoon nails (koilonychia): One of the most well-known changes with iron deficiency are so-called spoon nails. These nails are flattened and have a concave shape, similar to a spoon. They are often thin and can curve upwards.
Vertical ridges: Similar to vitamin B deficiency, vertical lines or ridges can also appear on the nails with iron deficiency, indicating disturbed cell division.
Pale nails: With iron deficiency, nails are often pale or have a pale, almost translucent color. This is because iron is necessary for the formation of red blood cells, which transport oxygen to the tissues, including the nails.
Brittleness and chipping: Iron deficiency can weaken the nails, causing them to break or chip easily.
White spots or streaks: Sometimes small white spots or streaks also appear on the nails, which can indicate a deficiency or disturbance in nail growth.

Foods rich in Vitamin B and Iron
Here are some foods rich in Vitamin B and iron, as well as recommendations on how much you should ideally eat daily to improve your body's levels. Please note that the exact amounts may vary depending on individual needs. For specific deficiency symptoms, it is always advisable to consult a doctor or nutritionist. Foods high in Vitamin B: Whole grain products: Whole grain bread, oatmeal, brown rice Recommended amount: 2-3 servings daily (depending on needs and energy requirements) Meat: Beef, chicken, turkey Recommended amount: 2-3 times a week, approx. 100-150 g per serving Fish: Salmon, mackerel, trout Recommended amount: 2-3 times a week, 100-150 g per serving Eggs: The yolk, in particular, is rich in Vitamin B12 and B7 (Biotin) Recommended amount: 3-4 eggs per week Dairy products: Milk, yogurt, cheese Recommended amount: 2-3 servings daily Legumes: Lentils, chickpeas, beans Recommended amount: 2-3 times a week, 150 g per serving Nuts and seeds: Almonds, sunflower seeds, flaxseeds Recommended amount: 30 g daily Foods high in iron: Red meat: Beef, lamb Recommended amount: 2-3 times a week, 100-150 g per serving Liver: Especially beef or chicken liver (rich in iron) Recommended amount: 1-2 times a month, 50-100 g Legumes: Lentils, chickpeas, beans Recommended amount: 2-3 times a week, 150 g per serving Green leafy vegetables: Spinach, kale, Swiss chard Recommended amount: 100-200 g daily Dried fruits: Apricots, raisins, figs Recommended amount: 30-50 g daily Nuts and seeds: Pumpkin seeds, sesame Recommended amount: 30 g daily Important notes: Vitamin B12 is mainly found in animal products. Vegetarians and vegans should rely on fortified foods or supplements. Improve iron absorption: Vitamin C promotes iron absorption. It is therefore advisable to combine iron-rich meals with Vitamin C-rich foods such as citrus fruits, bell peppers, or broccoli. Regularity: To achieve better levels in the body, you should regularly incorporate these foods into your diet, ideally daily or at least several times a week. If you have specific blood values, your doctor can give you more precise recommendations on how much of certain foods or supplements you need.

Summary :
If you observe such changes in yourself, it is advisable to consult a doctor. A blood test can confirm the deficiency and help you initiate the correct treatment. Furthermore, a balanced diet with sufficient vitamin B and iron is essential for healthy nails and your general health. Protect your nails with UV nail wraps, my personal tip. Avoid nail salons that are not always the gentlest and most hygienic option.
