Chokeberry and Lovastatin

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Lovastatin

Lovastatin falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Chokeberry interacts with.

Theoretically, chokeberry might increase levels of drugs metabolized by CYP3A4.
In vitro research shows that chokeberry inhibits CYP3A4. In humans, there is one case report of a drug interaction with trabectedin, a CYP3A4 substrate, which is hypothesized to have been caused by chokeberry inhibition of CYP3A4.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: your body relies on a liver enzyme called CYP3A4 to clear lovastatin. Chokeberry, at least in test-tube studies, seems to slow that enzyme down a bit. If that happens in real life, more lovastatin could linger in your blood than expected, which in theory could nudge up the risk of statin side effects like muscle aches, weakness, or (rarely) more serious muscle problems.

That said, I don't want to scare you. This is mostly theoretical, based on lab work and one case report with a different drug, not strong human evidence. Eating chokeberry as juice or jam is unlikely to cause trouble. Concentrated supplements are the bigger unknown, so before starting one, just run it by your pharmacist or doctor so they can keep an eye on things.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

See Every Supplement That Interacts With Lovastatin

This page covers Chokeberry only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Lovastatin page lists 184 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Apple (major), Beer (major), Grapefruit (major) and Siberian Cocklebur (major).

By severity: 8 major · 140 moderate · 36 minor.

From our pharmacist’s overview on the Lovastatin page

“Lovastatin (Mevacor) lowers cholesterol, and the liver clears it through an enzyme called CYP3A4, which is where most of these 184 supplements collide with it. This list deserves careful attention.”

About Chokeberry

What is Chokeberry?

Chokeberry
  • Antioxidant support
  • Heart and blood vessel health
  • Blood pressure support
  • Blood sugar support
  • Common cold symptoms
  • Anti-inflammatory support

Chokeberry (aronia) is a dark berry rich in antioxidants called polyphenols, and it's widely eaten as juice, jam, and supplements. Early research hints it may support heart health, blood pressure, and blood sugar, but the evidence is still limited and far from proven. It's generally well tolerated as a food, but talk to your pharmacist or doctor before using concentrated supplements.

About Lovastatin

What Is Lovastatin Used For?

Brand names: Mevacor, Altocor

Lovastatin is used to lower high LDL ("bad") cholesterol and total cholesterol in people whose levels have not improved enough with diet alone. It is also used to slow the buildup of plaque in the arteries (coronary atherosclerosis) in people who already have coronary heart disease.

In adults without existing heart disease but with high cholesterol and low HDL ("good") cholesterol, lovastatin tablets are approved to reduce the risk of heart attack, unstable angina, and the need for procedures to open blocked arteries. Lovastatin tablets are also approved for adolescents aged 10–17 with a specific inherited condition called heterozygous familial hypercholesterolemia (heFH), when diet changes alone haven't been enough.
