The Grapefruit Interaction Warning: A Direct Explanation

This is the single most important safety detail in this formula's blend, worth understanding on its own rather than buried in a longer ingredient list.

What the interaction actually is

Grapefruit extract inhibits the CYP3A4 enzyme, which the body uses to metabolize a wide range of medications — inhibiting it can cause those medications to build up to higher-than-intended blood levels.

Which medication categories are most affected

Some statins, calcium channel blockers, and immunosuppressants are among the medication categories most commonly affected by this interaction — a pharmacist can confirm whether anything you take specifically applies.
