Brittle / ridged nails
Nail fragility or surface changes; their appearance alone cannot diagnose a nutrient deficiency.
Anthony William’s proposed explanation; not an established medical cause
This department is a course in understanding, not a clinic. Nothing here is medical advice, diagnosis, or a treatment plan. If you are ill, pregnant, feeding a child, or taking medicine, speak with a clinician who knows your case. Emergency symptoms need emergency care.
William’s account
William proposes that zinc used in fighting EBV becomes depleted and contributes to nail changes.
Medical context
Nail changes have multiple explanations. Check for local damage, infection or other illness rather than assuming zinc deficiency; excess supplemental zinc can be harmful.
The medical reference explains assessment and established care options. The foods and supplements shown here record William’s approach; they do not replace that care.
