Stohs, Sidney J., Hartman, Michael J. (2015). Review of the Safety and Efficacy of Moringa oleifera. Phytotherapy Research.
This systematic review examined the safety and effectiveness of Moringa oleifera by analyzing existing research studies. The authors reviewed five human clinical studies that investigated moringa's effects on blood sugar and cholesterol levels. Research suggests that moringa demonstrated anti-hyperglycemic properties, meaning it may help lower elevated blood glucose levels, and anti-dyslipidemic effects, indicating potential benefits for managing abnormal blood lipid profiles. Animal studies consistently showed a high degree of safety with moringa supplementation. Importantly, none of the human studies reported adverse effects from moringa use, suggesting good tolerability in clinical settings. However, the review identified a significant concern regarding product standardization. The lack of standardized moringa preparations makes it difficult to compare results across studies and ensure consistent dosing. This variability in product quality and composition represents a major challenge for both researchers and consumers. The review highlights the need for better quality control and standardization in moringa products to ensure reliable therapeutic effects and safety profiles.
