Sulforaphane and Sertraline

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Sertraline

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

Theoretically, sulforaphane might increase the levels and effects of CYP3A4 substrates.
Animal and in vitro research shows that sulforaphane inhibits CYP3A4 enzyme activity and downregulates its expression. This interaction has not been reported in humans.
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 gist: your body uses an enzyme called CYP3A4 to help break down sertraline, and lab and animal studies suggest sulforaphane can slow that enzyme down. If that happened in people, sertraline might clear a little more slowly and build up slightly, which could nudge up its usual side effects, things like nausea, jitteriness, trouble sleeping, headache, or an upset stomach.

The important part: this is theoretical. It has only been seen in test tubes and animals, never reported in actual patients, so I wouldn't lose sleep over it. The broccoli on your dinner plate is very unlikely to matter. A concentrated sulforaphane supplement is a different story, so just run it past your pharmacist or doctor before adding one.

  • 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.

About Sulforaphane

What is Sulforaphane?

  • Antioxidant support
  • General cellular health
  • Detoxification support
  • Inflammation
  • Skin and aging concerns

Sulforaphane is a natural compound found in broccoli and other cruciferous vegetables that has shown promising antioxidant and anti-inflammatory effects in lab studies, but strong human evidence for most specific health claims is still limited. It is generally well tolerated as part of a vegetable-rich diet, but if you take a concentrated supplement, talk to your pharmacist or doctor first.

About Sertraline

What Is Sertraline Used For?

Brand name: Zoloft

Sertraline treats a range of mental health conditions. All formulations are approved for major depressive disorder (MDD) in adults and obsessive-compulsive disorder (OCD). The oral solution (including Zoloft oral solution) and several tablet formulations are also approved for panic disorder, post-traumatic stress disorder (PTSD), social anxiety disorder, and premenstrual dysphoric disorder (PMDD).

For OCD specifically, the capsule formulations and some tablet products are approved for use in adults and children aged 6 and older. Sertraline hydrochloride tablets (plain, not film-coated) are approved for OCD in pediatric patients as well. However, sertraline is not approved for major depressive disorder in children — only in adults.
