Nails are indicators of overall health, and brittle, discoloured, or breaking nails may indicate nutritional deficiencies. Nutrients like biotin, iron, and vitamin E are essential for nail health. Supplements like CBD can improve nail appearance and strength. Protein is crucial for healthy nail growth, and a balanced diet with adequate vitamins, including B vitamins, is essential. Zinc is essential for biological processes, and a healthy diet rich in zinc can prevent zinc deficiency and promote healthy nail growth. Nail care tips include keeping nails clean and dry, moisturising regularly, trimming nails, using gloves, and avoiding harsh chemicals. CBD oil, with its anti-inflammatory and antioxidant properties, can nourish and strengthen nails by preventing infections and reducing inflammation.
