Notes for this study:
After ingestion of 1.5g mate extract via 5 capsules (each contributing 0.3g lyophilised extract) were ingested by young (25+/-5yr) and otherwise healthy young men and women. 97 persons were recruited, but 12 subject to Yerba Mate.

Via indirect calorimetry, a lower respiratory quotient was seen indicating more energy coming from fat mass after Yerba Mate. No changes in energy expenditure overall were seen.

A significant decrease in heart rate was seen following Yerba Mate capsules, no influence on blood pressure.
