Short answer: White Mulberry Leaf is described as inhibiting alpha-glucosidase enzymes, reducing carbohydrate breakdown and absorption — a specific, named digestive-level mechanism.
Why this specific enzyme matters for post-meal glucose
Alpha-glucosidase enzymes break down complex carbohydrates into simpler sugars for absorption — slowing this process is a genuinely plausible way to reduce how quickly sugar enters the bloodstream after a meal.
What "reducing post-meal blood sugar spikes within 14 to 21 days" actually claims
This is a specific, named timeframe attached to this mechanism — worth treating as the marketing's own stated expectation rather than a guaranteed, individually verified outcome.
💡 Worth knowing: this describes the ingredient's general mechanism of action, not a clinical trial result for this specific finished formula.
