Moringa and Olanzapine

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

Minor

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Olanzapine

Olanzapine falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Moringa interacts with.

Theoretically, moringa might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that moringa extract induces CYP1A2 enzymes.
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 basic idea with moringa and olanzapine. Your body clears olanzapine mainly through a liver enzyme called CYP1A2. Some early lab studies suggest moringa might speed that enzyme up. If that happened in real life, your body could clear olanzapine a little faster, which in theory could make it slightly less effective. For someone managing schizophrenia or bipolar disorder, that could mean symptoms aren't as well controlled.

I want to be honest, though: this is only a theoretical concern based on test-tube research, not human studies, so the real-world effect is likely small or none. Food amounts in cooking are even less of a worry than concentrated supplements. Still, if you plan to use moringa regularly, check with your pharmacist or doctor first so they can watch how you're doing.

About Moringa

What is Moringa?

  • Nutritional supplement
  • Blood sugar support
  • Cholesterol support
  • Inflammation
  • Skin conditions

Moringa is a nutrient-rich plant whose leaves are widely used as a food and supplement, especially in parts of the world where malnutrition is common. Early research hints at possible benefits for blood sugar, cholesterol, and inflammation, but the human evidence is limited and not strong enough to recommend it as a treatment. Talk with your pharmacist or doctor before using moringa, especially if you are pregnant, breastfeeding, or taking medications.

About Olanzapine

What Is Olanzapine Used For?

Brand name: Zyprexa

Olanzapine treats schizophrenia and the manic or mixed episodes of bipolar I disorder in both adults and adolescents (ages 13–17). It can also be used alongside valproate or lithium to treat manic or mixed episodes in adults. When combined with fluoxetine, olanzapine tablets and orally disintegrating tablets are used to treat depressive episodes associated with bipolar I disorder and treatment-resistant depression in adults.

Olanzapine intramuscular injection (short-acting) is used by healthcare providers to quickly calm acute agitation in adults with schizophrenia or bipolar I mania. Zyprexa Relprevv — a separate, long-acting intramuscular formulation available only through a restricted program — is indicated specifically for the treatment of schizophrenia in adults.
