Short answer: Grapefruit extract inhibits the CYP3A4 enzyme, which can raise blood levels of a long list of medicines including some statins, calcium channel blockers and immunosuppressants. This is the one most worth flagging to a pharmacist.
Why this specific interaction is singled out above the others
Grapefruit's effect on CYP3A4 is one of the better-documented food-drug interactions there is — a direct, unusually candid statement pointing to genuinely established pharmacology, not a speculative caution.
Why this matters even though grapefruit is a familiar, everyday food
People often don't expect a supplement ingredient with a fruit name to carry a serious medication interaction — this is exactly the kind of detail a product's own marketing tends not to mention.
💊 Worth knowing: a pharmacist can check your specific list in a couple of minutes, free of charge — do not rely on a supplement website, including this one, to make that judgement for you.
