Mangiferin is a xanthone C-glycoside primarily found in mango leaves and bark that demonstrates anti-inflammatory and metabolic regulatory properties. The compound works by activating AMPK pathways and modulating immune cell differentiation, particularly affecting Th1, Th2, and Th17 cell responses.
Origin & History
Mangiferin is a natural xanthone glycoside derived primarily from mango tree leaves (Mangifera indica), though it is also found in other plants. It is typically extracted through solvent-based methods, with standardized extracts commonly containing ≥60% mangiferin by HPLC analysis.
Research Narrative (Provisional)
Despite extensive preclinical research, no substantial clinical trials have been conducted to confirm mangiferin's therapeutic benefits in humans. One acute human study assessed cognitive effects of a 300 mg mango leaf extract (standardized to ≥60% mangiferin) in healthy individuals, though specific outcomes were not detailed. The absence of PubMed-indexed human RCTs or meta-analyses means mangiferin remains in the preclinical development stage.
Preparation & Dosage

Reported Mechanism (Provisional)
Mangiferin activates adenosine monophosphate-activated protein kinase (AMPK) in hepatic, muscle, and adipose tissues, promoting glucose uptake and fatty acid oxidation. The compound modulates nuclear factor-kappa B (NF-κB) signaling pathways, reducing pro-inflammatory cytokine expression. Additionally, mangiferin influences T-helper cell differentiation by regulating transcription factors GATA-3, T-bet, and RORγt, which control Th2, Th1, and Th17 cell development respectively.
Clinical Narrative (Provisional)
Current evidence for mangiferin consists primarily of preclinical animal studies and in vitro research, with limited human clinical data available. Animal studies using doses of 10-100 mg/kg have demonstrated improved glucose tolerance and reduced inflammatory markers in diabetic and asthmatic models. Small preliminary human studies suggest potential benefits for metabolic parameters, but sample sizes have been limited to fewer than 50 participants. The respiratory health benefits remain confined to animal models of allergic airway inflammation, requiring human validation.
