Griffonia Simplicifolia and Aripiprazole

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

Moderate

CNS DEPRESSANTS

Why this applies to Aripiprazole

Aripiprazole falls under CNS DEPRESSANTS — the group Griffonia Simplicifolia interacts with.

Theoretically, taking Griffonia simplicifolia seed extract with CNS depressants might increase the risk of additive CNS depression.
Griffonia simplicifolia seed extract contains 5-HTP. In clinical trials, 5-HTP has been associated with drowsiness and somnolence.
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: Griffonia seed extract supplies 5-HTP, which your body turns into serotonin. In studies, 5-HTP has been linked to drowsiness and sleepiness. Aripiprazole (Abilify) can also cause tiredness, dizziness, or feeling slowed down in some people. Stack the two together and those calming effects may simply add up, so you could feel more drowsy or foggy than usual.

I want to be honest about the evidence here. This concern is mostly theoretical, based on how each one works rather than strong human studies, so it's not a guaranteed problem. Aripiprazole is not a prodrug, and the supplement doesn't change how your liver handles it. Still, because both touch serotonin and alertness, please check with your pharmacist or doctor before combining them, and don't change your aripiprazole on your own.

About Griffonia Simplicifolia

What is Griffonia Simplicifolia?

Griffonia Simplicifolia
  • Low mood
  • Sleep problems
  • Anxiety
  • Appetite control
  • Headaches

Griffonia simplicifolia is a West African shrub whose seeds are a natural source of 5-HTP, a building block of the brain chemical serotonin. Some people use it for mood, sleep, and appetite, but high-quality human evidence is limited, and it should not replace prescribed treatment. Talk with your pharmacist or doctor before using it, especially if you take medicines that affect serotonin.
