STOP: Zinc Supplementation For Endometriosis

Conventional Rationale

Endometriosis patients may present with low serum zinc levels. Standard practice treats this as a nutritional deficiency requiring supplementation.

Why It's Counterproductive

The microbiome signature reveals that the host is deliberately withholding zinc:

Calprotectin is elevated — it chelates and sequesters zinc away from pathogens as a nutritional immunity defense pendergrass 2026 endometriosis conference.

Zinc is a critical cofactor for pathogenic virulence enzymes:
- Zinc metalloprotease (E. coli, B. fragilis BFT) — degrades host tissues and inhibits the host immune system
- B. fragilis toxin (BFT) — the primary virulence factor of B. fragilis, zinc-dependent

Increased dietary zinc is directly associated with increased risk of endometriosis pendergrass 2026 endometriosis conference. Supplementing zinc overrides the body's deliberate zinc-sequestration strategy and arms the pathogens with the cofactor they need to degrade tissues and evade immunity.

Alternative Approach

Rather than supplementing zinc, the intervention strategy should:

- Support the body's calprotectin-mediated zinc sequestration
- Target pathogenic taxa through metal restriction (e.g., low nickel diet to disable glyoxalase)
- Restore depleted beneficial taxa through ecoli nissle 1917 (superior competitive exclusion)
- Replenish glutathione via nac supplementation to address the Cd/Pb burden
