How it works

Mulberry leaf extract triggers the liver and gut to make more enzymes that break down certain body chemicals linked to inflammation and poor blood sugar control. When these chemicals are broken down faster, the body’s metabolism improves. This effect happens directly in the tissues and doesn’t rely...

Most probable mechanism

In Simple Terms

A natural extract from mulberry leaves increases the activity of two enzymes in the liver and lower intestine that break down body chemicals called endocannabinoids. These chemicals normally promote inflammation and insulin resistance when present in excess. By boosting the enzymes that destroy them, the extract lowers their levels in the blood, which helps improve how the body handles sugar and fat.

Causal chain
1

Bioactive compounds in mulberry leaf extract are absorbed from the gastrointestinal tract and reach systemic circulation, where they interact with liver and ileal cells.

2

These compounds increase the production of fatty acid amide hydrolase (FAAH) and N-acylethanolamine-hydrolyzing acid amidase (NAAA) in hepatocytes and ileal epithelial cells.

3

Elevated FAAH and NAAA enzyme levels accelerate the breakdown of the endocannabinoids anandamide (AEA) and 2-arachidonoylglycerol (2-AG) within liver and intestinal tissues.

Reduced concentrations of AEA and 2-AG in the bloodstream decrease activation of cannabinoid receptor 1 (CB1) in metabolic tissues, including liver, adipose, and intestinal cells.

Diminished CB1 signaling reduces inflammation, improves insulin sensitivity, and normalizes lipid metabolism in metabolic tissues.
