Your nails are made of keratin—a type of protein—and just like your skin and hair, they require consistent nutritional support to stay healthy. In this post, we’re diving into the most important vitamins and minerals your body needs to grow strong, smooth, and beautiful nails.
1. Biotin (Vitamin B7)
Biotin is probably the most famous nutrient when it comes to nail health—and for good reason. Studies have shown that biotin can increase nail thickness and reduce brittleness. It helps the body convert food into energy and supports the production of keratin.
Where to get it: Eggs, almonds, sweet potatoes, salmon, and biotin supplements.
2. Vitamin B12
B12 plays a key role in iron absorption and red blood cell formation. A deficiency may cause darkened nails, ridges, or poor nail growth. It’s particularly important for vegetarians and vegans to monitor their B12 levels.
Where to get it: Fish, meat, dairy, or B12 supplements if you’re plant-based.
3. Iron
Low iron levels (anemia) are a common cause of brittle or concave nails. Iron helps carry oxygen to the nail matrix, which is essential for proper nail growth.
Where to get it: Red meat, spinach, lentils, pumpkin seeds, and iron supplements.
4. Zinc
Zinc is involved in cell division and tissue growth—both vital for strong nails. A deficiency can cause white spots, slow growth, or thin, fragile nails.
Where to get it: Pumpkin seeds, chickpeas, cashews, oats, and whole grains.
5. Vitamin C
Vitamin C is an antioxidant that protects nail cells from damage and helps in collagen production, which supports nail structure. It also boosts iron absorption from plant sources.
Where to get it: Citrus fruits, strawberries, bell peppers, and broccoli.
6. Vitamin A
Vitamin A supports cell growth and regeneration. Lack of it can lead to dry, brittle nails. However, excess vitamin A (especially from supplements) can have adverse effects, so balance is key.
Where to get it: Carrots, sweet potatoes, leafy greens, and liver.
7. Magnesium
Magnesium helps synthesize proteins (like keratin) and supports enzymatic reactions that promote healthy nail growth. Deficiency may lead to vertical ridges or poor nail strength.
Where to get it: Nuts, seeds, legumes, whole grains, and dark chocolate.
So, Do You Need a Supplement?
If you eat a well-balanced diet rich in these nutrients, you might not need extra supplementation. However, if you're experiencing nail problems or have dietary restrictions, a high-quality supplement designed to support nail, skin, and hair health can help fill the gaps.
One option that’s gaining popularity for supporting nail health from within is Supranail. It’s a carefully formulated supplement made with vitamins, minerals, and plant-based compounds that target the root causes of weak, brittle nails. It’s especially helpful if your nails aren't responding to topical treatments alone.
Final Thoughts
Your nails are more than just a canvas for polish—they reflect what’s going on inside your body. Instead of hiding brittle or weak nails, support them from the inside with the right blend of vitamins and minerals.
If your nail health feels like a constant struggle, a natural supplement like Supranail could be the missing piece in your wellness routine.
Because true nail care doesn’t just happen in the salon. It starts on your plate—and in your daily habits.
