Codeage Leaky Gut Supplement
Checked against public sources on August 4, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Ingredient amounts are hidden inside “Concentrated Polyphenol Blend”. The panel lists “Concentrated Polyphenol Blend” (42.5 mg) as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 6 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits below that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
