Horizontal nail lines, also known as Beau’s lines, are grooves or ridges that run across the nails. They can appear after illness, stress, injury to the nail, or as a sign of nutrient deficiencies. While sometimes temporary, these lines can affect the appearance of your nails and may indicate that your body needs additional support.
Natural supplements can be a gentle, effective way to encourage healthy nail growth and reduce the likelihood of developing horizontal nail lines in the future.
Biotin
Biotin (Vitamin B7) plays a key role in supporting keratin production, the protein that makes up your nails, hair, and skin. A deficiency in biotin can weaken nail structure, making them more prone to ridges and lines. Supplementing with biotin helps strengthen the nail bed and promotes smoother, more consistent nail growth.
- Mechanism of action: Enhances keratin infrastructure to strengthen and smooth nail growth
- Dosage or usage tip: 2,500–5,000 mcg daily, often taken as a capsule or gummy

Vitamin E
Vitamin E is a powerful antioxidant that supports circulation and protects nail cells from oxidative stress. Inadequate blood flow or free radical damage can contribute to nail abnormalities such as horizontal lines. Supplementing with Vitamin E may help improve nail strength, resilience, and growth consistency.
- Mechanism of action: Provides antioxidant protection and improves circulation to the nail matrix
- Dosage or usage tip: 200–400 IU daily, best taken with meals containing healthy fats

Summary
Horizontal nail lines can be unsettling, but they are often a signal that your body needs extra nutritional support. Biotin strengthens keratin structure for smoother nails, while Vitamin E boosts circulation and protects nail cells from damage. Together, these supplements can promote stronger, healthier nails and help reduce the recurrence of ridges and lines.
