Nutrition for Healthy, Strong Nails

Your nails can reveal a lot about your overall health. Brittle, slow-growing or discoloured nails may indicate that your body is lacking key nutrients. Like hair and skin, nails require a steady supply of vitamins, minerals and structural components to grow strong and resilient.

Biotin — The Key Nutrient for Nail Maintenance

Biotin (vitamin B7) is recognised for its contribution to the maintenance of normal nails. It supports the production of keratin, the structural protein that forms nail plates. Studies have shown that adequate biotin intake is associated with improved nail thickness and reduced brittleness over time.

Minerals for Nail Strength

  • Zinc contributes to normal protein synthesis, which is essential for nail growth and repair. It also supports the maintenance of normal skin and nails.
  • Copper plays a role in cross-linking collagen and elastin, contributing to the structural integrity of nail tissue.
  • Selenium contributes to the maintenance of normal nails and helps protect cells from oxidative stress.

Plant Extracts — Traditional Support for Nails

Several plant extracts have a traditional history of use for nail health:

  • Horsetail extract (Equisetum arvense) — naturally rich in silica, a mineral that contributes to connective tissue structure and nail strength.
  • Bamboo extract — another concentrated source of plant silica, supporting nail resilience.
  • Millet extract — traditionally used to support hair and nail strength.

Nutri-Leaf Skin Hair & Nails combines horsetail, bamboo, millet, nettle and rosemary leaf extracts with biotin, zinc, copper, selenium and vitamin C. One capsule daily provides comprehensive nutritional support for strong, healthy nails.

Practical Tips for Nail Health

  • Protect your hands — wear gloves when cleaning or using harsh chemicals.
  • Keep nails trimmed and filed to prevent breakage.
  • Moisturise hands and cuticles regularly.
  • Avoid using nails as tools for opening or scraping.
  • Be patient — nails grow slowly, and nutritional improvements take several months to become visible.

Key takeaway: Biotin contributes to the maintenance of normal nails, supported by zinc, copper, selenium and silica-rich plant extracts. Consistent daily supplementation over several months, combined with good nail care habits, provides the best foundation for nail health.
