Vascepa is a prescription medication used to reduce triglyceride levels in adults. It contains the active ingredient icosapent ethyl, which is a form of omega-3 fatty acid. According to the sources provided, there are several supplements that may interact negatively with Vascepa.

Firstly, supplements that contain omega-3 fatty acids should be used with caution when taking Vascepa. This is because both Vascepa and omega-3 supplements can lower triglyceride levels, and taking them together may increase the risk of side effects such as bleeding. [2]

Secondly, supplements that have blood-thinning properties, such as garlic, ginkgo biloba, and vitamin E, may also interact negatively with Vascepa. This is because Vascepa can also have blood-thinning effects, and taking these supplements together may increase the risk of bleeding. [3]

Thirdly, supplements that contain high levels of vitamin A should be avoided when taking Vascepa. This is because Vascepa can increase the body's levels of vitamin A, and taking supplements that contain high levels of this vitamin may lead to toxicity. [1]

It is important to note that these are not the only supplements that may interact negatively with Vascepa. Before taking any supplements while on Vascepa, it is recommended to consult with a healthcare provider to ensure that there are no potential interactions.
