Story at-a-glance
- Nail growth slows by 50% over a lifetime, making it a reliable indicator of overall aging and metabolic health
- Aging nails become brittle, thickened, and dull due to changes in keratin structure, decreased blood circulation and nutritional deficiencies
- If you have poor circulation or a metabolic issue like hypothyroidism, your nails start to grow slower, develop ridges, and lose the visible half-moon shape at the base, called the lunula. When the lunula fades or disappears, it can be a sign that your body isn’t getting enough nutrients or oxygen to support healthy nail growth
- Nutrients like collagen, biotin and iron are essential for maintaining strong, healthy nails and preventing structural damage
- Lifestyle choices such as minimizing vegetable oils from ultraprocessed foods, increasing carbohydrate intake and improving blood flow to the extremities significantly enhance nail health and slow signs of aging
