Nail splitting, also called onychoschizia, is a common nail concern where nails become weak, brittle, and prone to breaking into layers. This condition can make nails appear uneven, fragile, and unhealthy. For many people, it’s not just cosmetic—it can also cause discomfort, interfere with daily activities, and make nail care frustrating.
Common causes of nail splitting include frequent exposure to water, harsh chemicals, aging, or nutrient deficiencies. Alongside protective nail care habits, natural supplements can strengthen nails from within, making them healthier and more resilient.
Here are two evidence-based supplements that may help with nail splitting.
Biotin
Biotin, or vitamin B7, is one of the most well-known nutrients for nail health. It plays a key role in keratin production, the protein that forms nails, hair, and skin. Studies show that biotin supplementation can increase nail thickness, reduce brittleness, and lower the risk of splitting.
- Mechanism of action: Supports keratin production to strengthen nail structure
- Dosage or usage tip: 2,500–5,000 mcg daily, often available in capsules, gummies, or tablets

Collagen Peptides
Collagen is the most abundant protein in the body and is essential for skin, hair, and nail structure. Supplementing with collagen peptides has been shown to improve nail growth, reduce breakage, and enhance overall nail strength. Collagen also provides long-term support for reducing brittleness and splitting.
- Mechanism of action: Strengthens nails by supporting connective tissue and improving elasticity
- Dosage or usage tip: 5–10 grams daily, usually taken as a powder mixed into water, smoothies, or coffee

Summary
Nail splitting can be frustrating, but targeted supplements may help restore nail strength and resilience. Biotin supports keratin production, making nails stronger and less brittle, while collagen peptides provide structural support to reduce breakage and promote smoother, healthier nails. Together, these supplements can help you achieve stronger nails and reduce splitting over time.
Always consult with a healthcare professional before starting new supplements, especially if nail splitting is severe, persistent, or accompanied by other changes in nail or overall health.
