Iron deficiency is a leading cause of spoon-shaped, brittle nails (koilonychia). Iron helps red blood cells carry oxygen to your nail beds, fueling growth and repair.
- Top Sources: Lean red meat (in moderation), spinach, lentils, pumpkin seeds, quinoa, and dark turkey meat.
- Pro-Tip: Pair plant-based iron (non-heme iron) with Vitamin C (bell peppers, citrus, strawberries) to boost absorption dramatically—a crucial combo as digestive efficiency changes.
The Hydration & Flexibility Team: Omega-3s & Biotin
Dry, flaky nails lack flexibility. Omega-3 fatty acids act as internal moisturizers, while Biotin (B7) is essential for metabolizing the amino acids that build keratin.
- Top Sources for Omega-3s: Fatty fish (saldom, mackerel, sardines), walnuts, chia seeds, and flaxseeds.
- Top Sources for Biotin: Eggs (cooked yolk is key), almonds, sweet potatoes, and mushrooms.
- Why It Works After 40: Omega-3s fight age-related inflammation that can disrupt nail growth cycles. Biotin levels can be affected by changes in gut bacteria, making dietary intake more important.
