Potential Side Effects
- Mild digestive upset (bloating, diarrhea) at higher doses
- Possible thyroid interference from goitrogenic compounds at very high doses
- Mild laxative effect in some individuals
- Rarely: allergic reactions in people sensitive to Moringaceae family
Drug & Supplement Interactions
- May potentiate effects of thyroid medications due to goitrogenic compounds
- May enhance blood-sugar-lowering effects of diabetes medications (additive hypoglycemia risk)
- May increase effects of blood pressure medications (additive hypotension)
- Avoid moringa root and bark — only the leaf is well-studied for safety
Maximum Dose
Do not exceed: 8g leaf powder daily (higher doses not well-studied in humans)
