From the Research
The recommended daily dose of Moringa (Moringa oleifera) for a healthy individual should not exceed 2000 mg/kg, as higher doses may cause liver and kidney damage, as indicated by the most recent and highest quality study 1. When considering the use of Moringa, it's essential to prioritize morbidity, mortality, and quality of life as outcomes. The available evidence suggests that Moringa can be a valuable nutritional supplement, rich in vitamins, minerals, antioxidants, and protein. However, it's crucial to be aware of the potential risks associated with high doses.
Some key points to consider:
- The study published in the Journal of Ethnopharmacology in 2022 1 found that doses above 2000 mg/kg may cause liver and kidney damage.
- Another study published in Toxicology Reports in 2018 2 found that a no observed adverse effect level (NOAEL) of the standardized Moringa seed extract was determined as 257 mg/kg bw/d, providing 100 mg/kg bw/d of the active compound MIC-1.
- A study published in the Journal of Basic and Clinical Physiology and Pharmacology in 2013 3 found that chronic administration of Moringa leaves might predispose to hepatic and kidney damage at doses of 200 and 400 mg/kg bw.
Given this information, it's advisable to start with a lower dose of about 500 mg (half a gram) and gradually increase to assess tolerance, not exceeding the recommended daily dose of 2000 mg/kg. Moringa can be consumed as a powder mixed into smoothies, water, or food, or taken as capsules (typically 400-500 mg each). Moringa leaf extract supplements may have different dosing recommendations based on concentration, so it's essential to follow product-specific instructions.
While generally considered safe, pregnant women, those on medication, or individuals with medical conditions should consult healthcare providers before use, as Moringa may interact with certain medications due to its potential effects on blood sugar and blood pressure.
