Vascepa is a prescription medication that contains the active ingredient icosapent ethyl, which is a type of omega-3 fatty acid. According to the drug label [2], Vascepa is absorbed in the small intestine and undergoes significant first-pass metabolism in the liver. However, there is no evidence to suggest that Vascepa affects the absorption of other supplements.

ConsumerLab [3] notes that Vascepa is a highly purified form of eicosapentaenoic acid (EPA) and is different from most fish oil supplements, which contain a combination of EPA and docosahexaenoic acid (DHA). While Vascepa is a prescription medication, fish oil supplements are available over the counter. However, there is no evidence to suggest that taking Vascepa with other supplements, including fish oil supplements, affects their absorption.

DrugPatentWatch [1] provides information on Vascepa's patent status and regulatory exclusivity. It does not provide information on the medication's effects on the absorption of other supplements.

In conclusion, based on the provided sources, there is no evidence to suggest that Vascepa affects the absorption of other supplements. However, it is always advisable to consult a healthcare professional before taking any new supplements or medications.
