Nail Health: The Unseen Indicators of Internal Health

Unveiling the Hidden Connections between Nail Health and Nutrient Levels

We often overlook the significance of our nails, but they can be a powerful indicator of our internal health. From subtle changes in colour and texture to more dramatic transformations, our nails can reveal a wealth of information about our diet and overall well-being.

What Do Our Nails Reveal?

Nail colour and texture can indicate nutrient deficiencies, such as iron, zinc, or B vitamins.
Nail shape and growth rate can be affected by overall health, including deficiencies in vitamins and minerals.
Nail changes can be a sign of underlying health issues, such as anemia, thyroid disorders, or autoimmune diseases.

Common Nutrient Deficiencies Linked to Nail Changes

Iron deficiency: Pale or spoon-shaped nails, often accompanied by anaemia.
Brittle nails: Can be a sign of zinc, vitamin A, or B-complex vitamin deficiencies, as well as poor protein intake.
B12 deficiency: Dark vertical lines or discolouration on the nails, which may reverse after treatment.
Folate deficiency: White nail beds or pale nails, often linked to low haemoglobin or protein deficiencies.
