Chrysin and Testosterone

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

Minor

TESTOSTERONE

Theoretically, chrysin might increase the effects and adverse effects of testosterone.
In vitro research suggests that chrysin and its sulfate conjugate inhibit testosterone metabolism. It is speculated that chrysin and its sulfate conjugate reduce the metabolism of testosterone by inhibiting cytochrome P450 3A4. This effect has not been reported in humans.
Severity Minor 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 thinking behind pairing chrysin with your testosterone therapy. In test-tube studies, chrysin appears to slow down an enzyme called CYP3A4, which is one of the pathways your body uses to break down testosterone. If that breakdown slows, a bit more testosterone could linger in your system, theoretically nudging up both the benefits and the side effects (think acne, oily skin, mood changes, or fluid retention). Chrysin can also act as a mild aromatase blocker in the lab, which is exactly why bodybuilders reach for it.

The important caveat: this has only been seen in lab dishes, never confirmed in real people, and the body absorbs very little chrysin to begin with. So I wouldn't lose sleep, but do mention it to your doctor or pharmacist before combining the two.

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 Testosterone

This page covers Chrysin only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Testosterone page lists 170 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Beer (major), Grapefruit (major), Siberian Cocklebur (major), St. John's Wort (major) and Wine (major).

By severity: 5 major · 129 moderate · 36 minor.

From our pharmacist’s overview on the Testosterone page

“The supplement list for testosterone therapy (Androgel, Testim, Nebido, and others) deserves real attention, mainly because five of its 170 entries are rated major and four of those are everyday items: grapefruit, St. John's wort, and alcohol in the form of beer or wine.”

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.

About Testosterone

What Is Testosterone Used For?

Brand names: Intrinsa, Testim, Androgel, Andropatch, Testogel, Nebido, Delatestryl, Natesto, Vogelxo

Testosterone replacement therapy is used in adult males whose bodies do not produce enough of their own testosterone. This includes primary hypogonadism — where the testes themselves fail due to causes such as Klinefelter's syndrome, injury, chemotherapy, or surgical removal — and hypogonadotropic hypogonadism, where the brain's signaling system (the hypothalamus or pituitary gland) fails to trigger testosterone production.

Testopel (subcutaneous pellets) may also be used to stimulate puberty in carefully selected males with clearly delayed puberty. The safety and efficacy of testosterone for age-related (late-onset) hypogonadism have not been established for most products, including AndroGel, Testim, Jatenzo, Kyzatrex, Natesto, Depo-Testosterone, Testosterone Cypionate, and Xyosted.
