Cofactor for hundreds of enzymes across immune response, protein synthesis, and wound healing.
Commonly discussed use cases
- Immune support (discussed)
- Skin
- Low dietary intake
Supposed / potential benefits
- Corrects low intake; immune role is well established
Common side effects
- Nausea on an empty stomach
- Metallic taste
Warnings & contraindications

Typical timing considerations
With food to avoid nausea; away from high-calcium or high-iron doses.

Oral
Questions to ask your clinician
- Is my dose in a safe long-term range?
- Should I pair it with copper?

Track this in Reta
Beta members get a ready-made tracker for Zinc — schedule, dose log, reminders, and check-ins — for organizing a clinician-directed routine. Personal tracking is available to everyone during the Public Beta.
Reta is a tracking and education tool — not a medical provider. Nothing here is a diagnosis, treatment, prescription, or dosing recommendation.
