Beautiful nails are not just the result of a professional manicure or artificial extensions. The right vitamins for nails can strengthen the nail plate, protect against breakage, smooth out ridges, and even help reduce discolouration. Yet it is surprisingly difficult to get all the nutrients your nails need through diet alone. So which vitamins and supplements should you focus on to achieve strong, healthy nails from the inside out?
Your Nails as a Window Into Your Health
Nails are often one of the first parts of the body to signal nutritional deficiencies. Brittle, peeling, ridged, or discoloured nails are rarely just a cosmetic issue — they can reflect what is happening inside the body. Weak nails that break easily may point to a lack of essential vitamins and minerals, while changes in colour or texture can sometimes indicate underlying health conditions.
Before starting any supplementation aimed at improving nail health, it is worth consulting a dermatologist to rule out conditions such as fungal infections, psoriasis, or thyroid disorders. Once medical causes are excluded, targeted supplementation can make a real, visible difference to the strength and appearance of your nails.
Vitamin A — For Smooth, Hydrated Nail Plates
Vitamin A is primarily responsible for cell regeneration. It helps maintain proper hydration levels in the skin, hair, and nails, and prevents excessive keratinisation — the hardening and drying out of tissues. When it comes to nails specifically, vitamin A supports healthy growth, adequate moisture levels, and a smooth nail surface. A deficiency in this vitamin often manifests as dry, brittle nails that crack and peel easily.
Good dietary sources of vitamin A include liver, sweet potatoes, carrots, and leafy greens, but supplementation may be beneficial when dietary intake is insufficient. Explore our vitamin A supplements for a range of options.
B Vitamins — For Faster Growth and Stronger Structure
The B-vitamin group plays a multifaceted role in nail health. Deficiencies in vitamins B1, B2, B6, and B12 are commonly associated with brittle, slow-growing nails and deformations of the nail plate. These vitamins actively stimulate nail growth and support the structural integrity of the nail bed.
Among the B vitamins, biotin (vitamin B7/H) deserves special attention. Often referred to as the "beauty vitamin," biotin is one of the most widely recommended supplements for nails, hair, and skin. It directly contributes to the strength of the nail plate and may help reduce brittleness and breakage when taken consistently over several months.
[tip:Biotin works best when taken regularly over at least 3–6 months. Results are gradual — nails grow at roughly 3–4 mm per month, so it takes time for newly strengthened nail tissue to fully replace the old.]
Vitamins C and D — Supporting Mineral Absorption
Vitamin C is well known for its immune-supporting properties, but it also plays a valuable role in nail health. Its antibacterial action may help protect the nail bed from inflammation, and — crucially — vitamin C enhances the body's absorption of iron, a mineral that directly contributes to strong, healthy nails. Iron deficiency is one of the most common causes of spoon-shaped, brittle, or ridged nails.
Vitamin D supports the body's calcium metabolism, and calcium is a key mineral for nail hardness and resilience. When vitamin D levels are low, calcium absorption suffers, which can lead to soft, peeling nails. Given that many Europeans are deficient in vitamin D — particularly during the darker months — supplementation is often a practical step toward better nail health.
Vitamin E — Antioxidant Protection and Better Circulation
Vitamin E is a powerful antioxidant that protects cells from free radical damage, supports the renewal of intercellular lipids, and strengthens blood vessels. For nails, this translates into improved circulation beneath the nail plate, which promotes healthier growth and a better overall appearance. Vitamin E also has a protective, strengthening effect on the nails themselves.
One note of caution: excessive vitamin E intake may cause a yellowish discolouration of the nails. Sticking to recommended dosages ensures you get the benefits without unwanted side effects.
Niacin (Vitamin B3/PP) — Regulating Skin and Nail Function
The positive effect of niacin on skin health is well established, and since nails are a product of the skin, this benefit extends directly to nail condition as well. Niacin supports proper skin function, improves blood flow to the extremities, and may enhance the overall colour and vitality of both the skin surrounding the nails and the nails themselves.

Beyond Vitamins — Practical Tips for Healthier Nails
Supplementation is most effective when combined with good daily nail care habits. A few practical changes can significantly speed up your results:
- Wear gloves when cleaning or washing dishes — prolonged contact with water and household chemicals weakens the nail plate and strips away protective oils
- Avoid harsh nail polish removers — acetone-based removers are particularly damaging and can cause drying, brittleness, and discolouration
- Moisturise your cuticles — nail oils and cuticle creams help keep the nail bed healthy and support new growth
- Eat a balanced diet — eggs, nuts, leafy greens, fish, and legumes all provide nutrients that support nail health naturally
Ultimately, external care protects against damage, but it is what you put into your body that determines the long-term strength and beauty of your nails. A well-chosen supplement targeting hair, skin and nails can provide the nutritional foundation your nails need to grow strong, smooth, and resilient.

These changes may indicate an underlying condition that requires medical attention.]
Key Takeaway: The most important vitamins for strong, beautiful nails are biotin (B7), vitamin A, the B-complex group, vitamins C and D (for mineral absorption), vitamin E, and niacin (B3). Combine consistent daily supplementation with good nail care habits for the best results — and always rule out medical causes with a dermatologist if your nails deteriorate suddenly.
