Limited evidenceBenefits
- Meta-analysis supports modest reductions in fasting blood sugar and HbA1c.
- RCT in prediabetic adults showed significant glucose improvements at 12 weeks.
- Leaves are nutrient-rich, with vitamins, minerals, and polyphenols.
Evidence summary
What moringa is
Moringa (Moringa oleifera), sometimes called the drumstick tree, is a fast-growing tree native to northern India and now widely grown in tropical regions. The leaves are rich in protein, vitamins, minerals, and polyphenols. The supplement is a dried leaf powder or capsule, often sold as a greens superfood.
What the human research shows
A 2020 review of 7 human and 23 animal studies found that moringa helped lower blood sugar levels. A randomised Spanish trial in prediabetic adults showed that moringa consumed as 6 daily capsules for 12 weeks significantly decreased fasting blood glucose and HbA1c. A meta-analysis supports modest reductions in blood sugar and cholesterol. We grade the evidence as limited but emerging.
