3/5 Evidence Score

Melostacio® (Botanic Healthcare) is a standardized mango leaf (Mangifera indica) extract providing a concentrated source of mangiferin — a C-glucosylxanthone with potent antioxidant, anti-inflammatory, and metabolic health properties. Mango leaves have been used in Ayurvedic and traditional medicine for millennia for blood sugar management and metabolic conditions. Modern research confirms mangiferin inhibits alpha-glucosidase, activates AMPK, and reduces inflammatory markers relevant to metabolic syndrome, type 2 diabetes prevention, and cardiovascular health.

Studied Dose 100–300 mg/day mangiferin (as Melostacio® standardized extract); metabolic effects within 8–12 weeks of supplementation
Active Compound Mangiferin (1,3,6,7-tetrahydroxyxanthone-C2-β-D-glucoside) — Melostacio® by Botanic Healthcare; standardized Mangifera indica leaf extract; primary bioactive mangiferin ≥40%

Benefits

Blood glucose and insulin management

Mangiferin inhibits intestinal alpha-glucosidase and alpha-amylase enzymes — slowing carbohydrate digestion and reducing postprandial glucose spikes. Additionally, mangiferin activates AMPK (the cellular energy sensor) in muscle and liver cells, improving glucose uptake and insulin sensitivity through mechanisms similar to metformin but from a natural botanical source.

Anti-inflammatory and antioxidant protection

Mangiferin's C-glucosylxanthone structure provides exceptional free radical scavenging activity and NF-κB pathway inhibition — reducing pro-inflammatory cytokine production (TNF-α, IL-6, IL-1β) that drives chronic metabolic inflammation. This anti-inflammatory activity complements and amplifies the blood sugar benefits by reducing the inflammation that impairs insulin receptor signaling.

Lipid profile and cardiovascular support

Clinical and preclinical studies confirm mangiferin supplementation improves lipid profiles — reducing total cholesterol, LDL, and triglycerides while modestly increasing HDL. These cardiovascular benefits, combined with improved insulin sensitivity and reduced oxidative stress, position Melostacio® as a comprehensive metabolic health ingredient.

Mechanism of action

1

AMPK activation and alpha-glucosidase inhibition

Mangiferin activates AMP-activated protein kinase (AMPK) by increasing the AMP:ATP ratio in metabolic tissues — triggering glucose transporter GLUT4 translocation to cell membranes for improved glucose uptake independent of insulin signaling. Simultaneously, mangiferin competitively inhibits intestinal alpha-glucosidase, reducing the rate of carbohydrate digestion and glucose absorption. The dual mechanism (improved peripheral glucose uptake + reduced glucose absorption) addresses blood sugar from both directions.

Clinical trials

1
Mangiferin for Type 2 Diabetes — RCT
PubMed

Randomized, double-blind, placebo-controlled trial of mangiferin supplementation in T2DM patients over 12 weeks. Outcomes: fasting glucose, HbA1c, postprandial glucose, lipids. (Na et al. 2014, J Med Food)

T2DM patients.

Mangiferin reduced fasting glucose, HbA1c, postprandial glucose vs placebo. Modest lipid improvements. Note: Melostacio® is a specific mango leaf extract — broader mangiferin literature applies but not all extracts are equivalent. Mango leaf has a long traditional use history in Cuba and elsewhere for diabetes management.

Side effects and drug interactions

Common Potential side effects

Generally very well tolerated at clinical doses
Mild GI effects possible — take with food
Mango allergy (rare) — avoid if known mango allergy (cross-reactivity with leaves)

Important Drug interactions

Antidiabetic medications (insulin, metformin, sulfonylureas) — additive glucose-lowering; monitor blood glucose closely
Anticoagulants — mangiferin has mild antiplatelet activity; monitor if on blood thinners
CYP enzyme interactions possible at high doses — mangiferin inhibits CYP2C8; monitor with CYP2C8-sensitive drugs

Frequently asked questions about Melostacio® (Mango Leaf Extract)
