CAFFEIC ACID Interactions
CAFFEIC ACID Overview Information

Caffeic acid is a chemical found in many plants and foods. Coffee is the primary source of caffeic acid in the human diet. However, it can be found in other food sources such as apples, artichoke, berries, and pears. Wine also contains a significant amount of caffeic acid.

Caffeic acid is used in supplements for boosting athletic performance, exercise-related fatigue, weight loss, cancer, HIV/AIDS, herpes, and other conditions.

How does it work?

Caffeic acid is thought to have many effects in the body including antioxidant and anti-inflammatory effects. It might also affect the immune system in the body. Test tube studies show that it might decrease the growth of cancer cells and viruses. Animal studies show that it might have a mild stimulant effect and reduce fatigue related to exercise. The effects of caffeic acid when taken by people are not known.
