MeltCore's marketing centers on a gut-bacteria mechanism: the idea that "harmful bacteria" sabotage weight loss, and that the formula promotes "good bacteria that activate fat burning." This is a specific, strong claim worth examining honestly.
Setting the gut-bacteria framing aside, the 6 named ingredients have more conventional, traditional mechanisms: Green Tea and Guarana for thermogenesis and energy, African Mango for appetite hormone regulation, Raspberry Ketones for fat-cell signaling, L-Carnitine for fatty-acid transport, and Grape Seed Extract for antioxidant support against inflammation.
The specific "attacks harmful bacteria, promotes good bacteria that activate fat burning" claim is not something we could verify against the named ingredients or independent evidence — none of the 6 described ingredients are probiotics or have well-established gut-microbiome mechanisms. The more conventional metabolism and appetite claims are more plausible, though still unverifiable at undisclosed doses.
