Inflammation is a natural response of the body to injury or infection, but chronic inflammation can lead to various health issues. While many people turn to dietary supplements in hopes of alleviating inflammation, some may actually exacerbate the problem. Here are five supplements that you should avoid if you have inflammation.

1. Omega-6 Fatty Acids

While omega-3 fatty acids can reduce inflammation, omega-6 fatty acids (found in many vegetable oils) can promote it. Common sources include corn oil, sunflower oil, and soybean oil. According to dietitian Christina Warner, high intake of omega-6 can lead to an imbalance that may worsen inflammatory conditions.

2. Iron Supplements

Excess iron can provoke oxidative stress and inflammation in the body. Dietitian Emily O’Brien notes that individuals should be cautious with iron supplementation, especially if they have underlying inflammatory conditions, as it can increase the risk of complications.

3. High-Dose Vitamin A

Vitamin A is essential for health, but taking it in large doses can lead to toxicity and increase inflammatory responses in certain individuals. According to research published in the Journal of Nutrition, excessive vitamin A can contribute to inflammation rather than mitigate it.

4. Excessive Calcium Supplements

While calcium is crucial for bone health, excessive supplementation has been linked to increased inflammation. A study in the American Journal of Clinical Nutrition indicates that too much calcium can be detrimental, particularly in individuals with existing inflammatory conditions.

5. Creatine

Often used for athletic performance, creatine may aggravate inflammation, particularly in those with kidney issues. Dietitian Michael Hartman advises that individuals experiencing chronic inflammation should avoid creatine boosters to prevent further complications related to inflammation.
