The stomach lining, also known as the gastric mucosa, is a protective layer of cells that lines the inside of the stomach. It plays a crucial role in shielding the stomach from the harsh acidic environment necessary for digestion. However, certain supplements can damage this delicate lining. It’s important to be mindful of supplement intake to protect the stomach and maintain digestive health.
To shed some light on two potentially harmful options, we spoke to family nurse practitioner Monelle Burrus. She told us that iron supplements and fish oil could damage your stomach lining. Learn more about the risks of each below.
1. Iron Supplements
Iron is crucial to your health, and if you are anemic or simply aren't getting enough of this mineral in your diet, supplements often serve as a good option. However, iron supplements can be rough on the stomach. Burrus warns that they "may lead to ulceration" and "can also corrode with the acids in the stomach, which would lead to irritation." To support iron levels, she suggests consuming natural sources like "spinach, beans, and lean meats," ideally combined with foods high in vitamin C to improve absorption.

2. Fish Oil
Fish oil can target a number of health needs thanks to the fact that it offers up healthy omega-3 fatty acids. Unfortunately, Burrus warns that it can upset the stomach. "High doses of Omega 3 fatty acids are healthy for the heart; however, they can cause stomach upset, heartburn, and can also cause bleeding problems mostly among those who are already taking blood thinner products," she explains. For a gentler option, she recommends choosing "enteric-coated capsules" or getting omega-3s from whole foods like walnuts and flaxseeds.
