Potential of Moringa oleifera to Improve Glucose Control for the Prevention of Diabetes and Related Metabolic Alterations: A Systematic Review of Animal and Human Studies.
Level 2 - randomized trial
Systematic review combining animal models and heterogeneous, limited human studies
PubMed 32664295 · doi:10.3390/nu12072050
What was done
A systematic review was conducted via PubMed and reference lists to evaluate the effects of *Moringa oleifera* (MO) on glucose metabolism. Thirty-three animal studies and eight human clinical studies were identified and reviewed, covering leaf and seed extracts, dry leaf powder, and aqueous preparations across acute and long-term exposures.
What was found
The abstract reports no numerical values or statistical outcomes. It notes that animal studies extensively demonstrated hypoglycemic effects and prevention of hyperglycemia-related metabolic alterations, while human trials primarily showed encouraging results in postprandial glucose regulation.
Why it matters
*Moringa oleifera* contains bioactive polyphenols and glucosinolates that may modulate glycemic control, though current human evidence remains preliminary.
Limits
The abstract highlights that human trials are scarce (n=8) with heterogeneous study designs, small cohorts of diabetic or prediabetic patients, and a lack of quantification for active bioactive compounds in the tested formulations. Most evidence rests on animal models.
