Acceptability of Moringa oleifera leaf powder among healthy adults in the United States

This randomized controlled trial examined how well healthy American adults tolerated different doses of moringa leaf powder over one week. Forty-five participants were divided into three groups receiving low, medium, or high doses of moringa powder. Research suggests that compliance was high across all dose groups, indicating participants were willing to consume the supplement as directed. However, those receiving higher doses experienced gastrointestinal symptoms like nausea or stomach discomfort, though these symptoms resolved quickly. Studies indicate that skin carotenoid levels increased during the trial, suggesting the moringa was being absorbed and utilized by the body. Taste acceptability emerged as a significant barrier, with many participants finding the powder unpalatable when consumed alone. The researchers found that incorporating the powder into food-based preparations significantly improved compliance and acceptability. This suggests that delivery method is crucial for long-term adherence to moringa supplementation. The study provides important insights into practical considerations for moringa use in Western populations, highlighting both the potential benefits and challenges of incorporating this nutrient-dense plant into American diets.
