Can you take Naringin and Red Yeast Rice together?
Naringin inhibits the enzyme that clears monacolin K (lovastatin) from the body, potentially raising its blood levels 2–5 fold. This is the same grapefruit–statin interaction that carries FDA warnings.
Severity
Warning
Evidence

Timing
Avoid combining entirely.
How it works
Naringin and its metabolite naringenin inhibit CYP3A4 and intestinal P-glycoprotein, dramatically reducing first-pass metabolism of monacolin K.
At elevated monacolin K levels, the risk of myopathy and rhabdomyolysis (muscle breakdown) increases substantially. This interaction is so well-established with prescription statins that FDA mandates grapefruit warnings on statin labels.
What to do
Avoid grapefruit, grapefruit juice, and naringin supplements entirely while taking red yeast rice. There is no safe timing separation — CYP3A4 inhibition lasts for hours.
Frequently asked
