Chrysin and Niacin, Lovastatin

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

Minor

GLUCURONIDATED DRUGS

Why this applies to Niacin, Lovastatin

Niacin, Lovastatin falls under GLUCURONIDATED DRUGS — the group Chrysin interacts with.

Theoretically, chrysin might increase the clearance of drugs that are UGT1A1 substrates, thereby reducing their effectiveness.
In vitro research suggests that chrysin might induce UDP-glucuronosyltransferase 1A1 (UGT1A1).
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Here's the honest scoop on combining chrysin with Advicor (the niacin and lovastatin combo pill). In test-tube studies, chrysin appears to nudge up an enzyme called UGT1A1, which helps the body package and clear out certain drugs. The worry on paper is that speeding up this pathway could lower the levels of medications it processes, making them work a little less well.

But honestly, I wouldn't lose sleep over this one. This is rated minor and unlikely, and the evidence is only from lab and animal work, not real people. On top of that, chrysin is famously poorly absorbed, so very little actually gets into your system. Realistically, your cholesterol control from the lovastatin and niacin shouldn't change much. Still, since this is theoretical, run any new supplement past your pharmacist or doctor first.

  • 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).

From our pharmacist’s overview on the Niacin, Lovastatin page

“Advicor pairs niacin with lovastatin to lower cholesterol, and because lovastatin is cleared by a single liver enzyme, CYP3A4, this list earns genuine respect. Of the 188 supplement and herbal ingredients on file, 121 interact through that one enzyme, and eight overall carry a major rating.”

About Chrysin

What is Chrysin?

  • Bodybuilding and testosterone support
  • Anxiety and stress
  • Anti-inflammatory
  • Antioxidant support
  • Prostate health

Chrysin is a plant flavonoid sold mainly as a bodybuilding supplement claimed to raise testosterone or block estrogen, but human studies have not shown these benefits, largely because the body absorbs very little of it. Evidence for its other proposed uses is mostly limited to laboratory and animal research, so its real-world value is unclear. Talk with your pharmacist or doctor before using it.
