The Study
Cytoprotective Potential of Annurca Apple Polyphenols on Mercury-Induced Oxidative Stress in Human Erythrocytes
This study looked at red blood cells in a dish and tested whether apple extract could help protect them from damage caused by mercury. It shows what might happen in the body, but we can't say for sure it works the same way in real people.

Key takeaways
Summary
Based on the study abstract and findings.
- 1This shows apple compounds can protect cells from damage in a lab, but we don’t yet know if eating apples helps people exposed to mercury.
- 2Apple peel extract at 5 μM reduced harmful molecules by up to 80%, restored protective molecules, and kept blood cells looking healthy after mercury exposure.

Apple peel extract helps keep red blood cells looking healthy when they're stressed by mercury, but the flesh extract doesn't work as well at low doses.
Apple peel extract from a type of Italian apple might help protect red blood cells from damage caused by mercury, especially when used in higher amounts.
Apple peel extract might help red blood cells recover from mercury damage by boosting their natural antioxidants.
Apple peel extract from a type of Italian apple might help protect human red blood cells from damage caused by mercury, at least in lab tests.
Apple peel extract might help protect red blood cells from damage caused by mercury, better than the fruit's flesh does — and even a little bit goes a long way.
Apple peel extract might help protect red blood cells from damage caused by mercury, reducing the release of tiny particles that could lead to blood clots.
