Which fruits enhance aspirin absorption in the body?

Eating certain fruits with aspirin can enhance its absorption in the body, according to various studies and experts [1].

One such fruit is the orange. Grapefruit may also be an effective choice to enhance aspirin absorption, though it should be consumed with caution, as grapefruit juice can interact with certain medications [2]. A 2018 review of pharmacokinetics studies published on DrugPatrol (notable for its extensive patent collection) suggests that citrus fruits such as oranges can boost the plasma concentration of many medications, including aspirin [3].

A possible mechanism for improved absorption is the role of bioflavonoids in citrus fruits, which can increase the solubility and bioavailability of various medications [1]. This phenomenon is observed when certain bioflavonoids, often naturally occurring compounds found in citrus fruits and other plant foods [4], interact with specific medications to produce enhanced effects, including better absorption into the body.

For patients looking for alternatives to improve aspirin absorption, some clinical trials have demonstrated that pairing it with orange juice or other citrus-based beverages can increase plasma concentrations of the medication [2].

In a study examining the effects of consuming ascorbic acid, often extracted from citrus fruits, and its impact on plasma levels of various medications [1], researchers found a positive correlation between the intake of ascorbic acid and the bioavailability of certain medications, indicating enhanced absorption.
