mineral · for bloating
Zinc Sulfate
Meant to tighten the seams between gut cells so less irritation gets through.
Say that in clinical terms
Zinc strengthens intestinal barrier integrity by upregulating tight junction proteins (occludin, ZO-1). It reduces intestinal permeability (leaky gut) which contributes to bloating, and supports digestive enzyme function including carbonic anhydrase.
How strong is the research?
Not verified evidence
1 paper read.
We read the research behind this and none of it concluded that it works for this. That is a finding about the papers, not a verdict that it does nothing.
How much to take
daily with meals
15–30 mg
Take with food to reduce nausea. Do not take with iron supplements. Balance with copper if using long-term (>30mg).
Before you take it
- The study dose delivers approximately 76 mg elemental zinc/day — nearly double the NIH UL of 40 mg/day; this cannot be a reference point for a 15–30 mg zinc picolinate recommendation
