Dietary supplement / essential mineral.

An essential mineral involved in immune function, skin, and hormone metabolism. Commonly tracked seasonally or during heavy training. Long-term high doses deplete copper — dose matters.

How it works

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

  • Chronic high doses cause copper deficiency
  • Separate from certain antibiotics (absorption)

Typical timing considerations

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

Administration route

Oral

Questions to ask your clinician

  • Is my dose in a safe long-term range?
  • Should I pair it with copper?

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.
