Nails can reveal a lot about your overall health, particularly when it comes to nutrient deficiencies. A well-balanced diet is essential for maintaining strong, healthy nails. When certain nutrients are lacking, it can lead to a variety of nail problems. In this article, we will explore how nutrient deficiencies can affect your nails and what you can do to keep them healthy.
Common Nutrient Deficiencies and Their Effects on Nails

Iron is crucial for the production of hemoglobin, which carries oxygen to your cells, including those that support nail growth.
Effects:

- Slow Growth: Nails may grow more slowly than usual.

Biotin, also known as vitamin B7, is important for the production of keratin, a key protein in nails.
Effects:
