Broccoli leaves, the Jeju raw material for Brocometa

Broccoli leaf (Brassica oleracea var. italica), the raw material for Brocometa · grown in Jeju, Korea.

Brocometa is a Jeju broccoli leaf extract developed for dual care of obesity and diabetes, supporting body fat reduction, blood sugar stabilisation and insulin sensitivity. It is standardised to the glucoraphanin and sulforaphane markers and produced by pulsed electric field (PEF) processing followed by ethanol extraction.

Functions & features

What Brocometa does

Body fat reduction
Blood sugar stabilisation
Improves insulin sensitivity
Antioxidant

Brocometa targets body fat reduction, blood sugar stabilisation, improvement of insulin sensitivity and antioxidant activity. In experimental work, these effects are linked to AMPK activation and improvement of insulin resistance.

Experimental results

Pre-clinical findings

−56%

Net reduction in blood triglycerides (TG) with broccoli leaf extract (BLE).

−50%

Net reduction in fasting glucose with broccoli leaf extract (BLE).

Results from dosing broccoli leaf extract (BLE) at 500 mg/kg in an obese animal model (ob/ob), compared against the obese control. In lipid control, the triglyceride reduction outperformed the standard diabetic drug metformin.

Animal model — obese control (ob/ob) vs. broccoli leaf extract (BLE), 500 mg/kg
Metric	Obese control (ob/ob)	BLE treated (500 mg/kg)	Net change
Blood triglycerides (TG)	2.7 mmol/L	1.2 mmol/L	−56%
Fasting glucose	460 mg/dL	232 mg/dL	−50%

PEF-optimised sulforaphane content

PEF-optimised processing raised sulforaphane (SFN) content by 137% versus the standard method, through enhanced biotransformation.

Sulforaphane (SFN) content — standard method vs. PEF-optimised method
Component	Standard method	PEF-optimised method	Enhancement
Sulforaphane (SFN) content	16.8 mg/unit	39.9 mg/unit	+137%
