Moringa (Moringa oleifera) is a tree whose leaves, seeds and other parts are used in traditional medicine, and whose leaves and young seed pods are eaten as food. As a supplement, usually leaf powder, it has been studied mainly for blood sugar, cholesterol and blood pressure.
Also known as: Moringa oleifera, moringa leaf powder, drumstick tree.
Moringa has no RDA or upper limit, and there is no NIH fact sheet for it. The trials in the 2025 meta-analysis (Crișan) used different amounts and lengths, so there is no single study amount to quote.
It is sold in the US as a dietary supplement. Under the 1994 dietary supplement law (DSHEA), FDA does not approve dietary supplements before they are marketed, and the maker, not FDA, is responsible for safety and labeling.
A 2025 meta-analysis (Crișan) of 9 randomized trials with 649 adults found no significant effect of moringa on most heart and metabolic outcomes, including weight, cholesterol and blood sugar. It found a modest drop in diastolic blood pressure, but that result did not hold up in sensitivity analyses, and the certainty of the evidence was very low for every outcome. The authors said current evidence does not support consistent benefits.
A 2015 review (Stohs), written by authors from a supplement company, reported no adverse effects in human studies and a high degree of safety in animal studies of leaf extracts, but noted that products are not standardized. If you take diabetes or blood pressure medicine, tell your prescriber before adding moringa.
We could not find a single published half-life or time to peak for moringa that applies to a supplement dose, so we do not list one. Herbal products are mixtures of many plant compounds, so no single figure would describe them.
