What are the benefits of grapefruit?
One mechanism of reducing the risk of cardiovascular disease is through an antioxidant effect. Grapefruit has a high antioxidant potential, with red varieties having higher potentials than white. 3 Many different bioactive compounds have been isolated from grapefruit and studied. 1 Grapefruit is high in dietary fiber and several antioxidants, particularly phenolics. 3 Naringin, one of the more abundant phenolics, has demonstrated lipolytic effects in animal and in vitro studies. 4 Another related compound is hesperidin, which showed blood pressure reducing activity in vitro. 5 A direct effect on serum lipid levels has been proposed, although evidence to support this is not yet available.
Can grapefruit cause drug interactions?
Several drug-ju ice interactions occur, although normal consumption of grapefruit, rather than high volumes of juice, rarely appears to cause clinically significant interactions. Precise volume recommendations are rarely given, though 6-8 ounces per day is sometimes suggested. A complete list of drugs and their susceptibility to this interaction is available. 12
Does grapefruit juice affect CYP3A?
10 Drug plasma concentrations were 2-3 times higher than expected. 11 This is now known to be due to furanocoumarins present in grapefruit, which can degrade up to 50% of intestinal CYP3A enzyme. When consumed in usual dietary amounts, grapefruit juice selectively inhibits intestinal CYP3A enzymes and not those found in the liver . 12 The inhibition is persistent, being found to last at least 3 days. 11 However, people vary widely in their levels of CYP3A, leading to much individual variation in the extent of this interaction. Table 1 shows the impact of grapefruit juice on serum levels of several drugs metabolized via these enzymes. However, the practical significance of these interactions continues to be debated, and is likely more significant for juice than whole fruit due to a volume effect.
Does grapefruit lower cholesterol?
Research into the cardioprotective effects of grapefruit developed when a hybrid of the Asian citrus fruit pomelo and grapefruit (called sweetie fruit) was found to significantly reduce total cholesterol (TC), low-density lipoprotein cholesterol (LDL), and triglyceride (TG) levels in hypercholesterolemic patients, though there was no effect on high-density lipoprotein cholesterol (HDL) levels. 8 The peeled fruits were consumed. Animal studies found that grapefruit itself had a cholesterol-lowering effect. 3
Does grapefruit inhibit enzymes?
Several compounds called furanocoumarins have been isolated from grapefruit and shown to inhibit enzymes in the liver and intestines. 6 The most important of these are CYP3A enzymes, as these metabolize several drugs in the intestine, reducing their bioavailability. These findings raise concerns that grapefruit interactions may lead to higher plasma concentrations of drugs either enhancing clinical effects or causing adverse reactions. These same compounds also may have anticholesterolemic effects. 7
Is grapefruit good for you?
Grapefruit is low in calories; high in vitamin C, fiber, and antioxidants; and nutritious. It should be enjoyed as part of a heart-healthy diet and lifestyle. Patients stabilized on medications can consume a fresh grapefruit or a 10-ounce glass of grapefruit juice without fear of major adverse effects. Those taking drugs metabolized by intestinal CYP3A systems and with low oral bioavailability or a narrow therapeutic index should limit their consumption of grapefruit and grapefruit juice. Patients who have had difficulty stabilizing on a suitable dose of such medications should probably avoid grapefruit. People on medications such as those in Table 1 should avoid consuming large amounts of grapefruit.
Is grapefruit juice a CYP3A inhibitor?
With recent work identifying furanocoumarins as the CYP3A inhibitors, a method of removing 99% of these from commercial grapefruit juice has been developed. 12 Such juice does not significantly alter the bioavailability of felodipine. Furanocoumarin-free commercial juices are currently being developed.

Can grapefruit affect blood thinners?
Some other blood thinners, however, may be affected by grapefruit consumption. I say they ‘may be affected’ because there aren’t many formal studies that have been conducted on these newer medications with regard to how grapefruit may or may not impact them. However, they utilize that same CYP3A pathway in the gut as the previous medications, so it is prudent to moderate your consumption of grapefruit if you take any of these: ticagrelor (Brilinta), apixaban (Eliquis), or rivaroxaban (Xarelto) ( 10, 11, 12).
