For strong nails, focus on Biotin (B7), which helps keratin production, and other nutrients like Iron (for blood flow), Zinc (keratin formation), Vitamin C (collagen), Vitamin D, and Protein, best obtained through a balanced diet but also available in supplements. A deficiency in these can cause weakness, so ensuring adequate intake supports nail strength, hardness, and growth.
Ask your healthcare professional about biotin.
Some research suggests that the nutritional supplement biotin might help strengthen weak or brittle nails.
Weak nails are a sign of Vitamin B and C deficiency.
Brittle nails that split or crack easily may lack essential nutrients, especially B12. This vitamin helps deliver oxygen and nutrients to the nail bed, ensuring that nails grow thicker, stronger, and more resistant to breakage. Without enough B12, nails can become weak, dry, and prone to peeling.

Taking vitamin B12 daily is generally safe for most people, as it's water-soluble and excess is flushed out, but high doses can cause mild side effects like headaches, nausea, dizziness, or diarrhea in some individuals, while very high levels (especially from injections) might rarely link to other issues, so it's best to stick to recommended amounts unless treating a diagnosed deficiency.
Because of its involvement in protein synthesis, a process essential to nail growth, it's no surprise that magnesium helps create beautiful and strong nail plates. Sufficient mineral, vitamin, and nutrient intake is necessary to support the nail beds in growing nail tissue.
Symptoms of vitamin B12 or folate deficiency
Overview. Like the skin, the fingernails are a reflection of a person's state of health. Low levels of zinc and iron as well as thyroid problems can cause brittle nails.
Vitamin B12 is present in foods of animal origin, including fish, meat, poultry, eggs, and dairy products [5,12]. Plant foods do not naturally contain vitamin B12. However, fortified breakfast cereals and fortified nutritional yeasts are readily available sources of vitamin B12 that have high bioavailability [13,14].
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. The nail pigmentation associated with B12 deficiency is more frequent in patients with dark skin.
To prevent your nails from splitting, keep them dry, moisturize regularly, wear gloves for household chores, and maintain a healthy diet with biotin, iron, and zinc. Taking these steps can help strengthen and protect your nails.
Normal aging: Many people develop vertical ridges on their nails as they get older. These lines aren't dangerous. Skin conditions: If you have very dry skin or eczema, you may have vertical lines on your nails. Thyroid disease: If you have hypothyroidism, you may have thick, brittle nails with vertical ridges.
Clinical manifestations are often nonspecific and can include hair loss, dermatitis, conjunctivitis, and neurological symptoms such as depression, lethargy, and paresthesia. Biotin supplementation is commonly marketed for hair and nail health.
Your body needs magnesium to function normally. Symptoms of magnesium deficiency include low appetite, nausea or vomiting, muscle spasms or tremors and abnormal heart rhythms. A blood test or urine test can be used to diagnose magnesium deficiency. Magnesium deficiency is usually treated with supplements.

When taken in doses greater than 350 mg daily, magnesium is possibly unsafe. Large doses might cause too much magnesium to build up in the body, causing serious side effects including an irregular heartbeat, low blood pressure, confusion, slowed breathing, coma, and death.
Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables (such as sweet potatoes) [2,12].
In fact, some studies have even suggested the opposite. For instance, one study noted that individuals who regularly took vitamin B12 supplements gained between 2.5 to 17 fewer pounds (1.2 to 7.7 kg) over a decade than those who didn't supplement.
- Hydrates and protects: Vaseline forms a barrier that locks in moisture, helping to keep nails hydrated and preventing them from becoming dry and brittle.
According to Astrology, the moon is a powerful symbol associated with emotions, intuition, and natural cycles. Cutting nails in the evening, when the moon's influence is strong, is believed to disrupt personal energy fields. This can lead to imbalances that affect one's emotional well-being and intuitive clarity.
For stronger nails, take a biotin supplement, use a hand cream or cuticle oil, wear gloves when washing dishes, and remove nail polish without acetone.
