Brittle nails or nail changes

Linked to zinc, iron, biotin, and trace mineral insufficiency.

Accessibility Statement

Nails reflect long-term nutrient status. Brittle or weak nails often indicate trace mineral or vitamin insufficiency rather than surface damage.

Zinc, iron, biotin, and silica support nail matrix formation and strength. Deficiencies result in slow growth and structural weakness.

Consistent micronutrient intake supports stronger nail formation over time, reflecting improved internal nutritional balance.
