New Meta-Analysis Validates Blackcurrant Extract for Metabolic Efficiency

Published in the Journal of Dietary Supplements, the analysis pooled data from 226 participants to quantify how the 35% anthocyanin extract alters energy substrate utilization. Researchers found an average increase in fat oxidation of 0.042 g/min alongside a decrease in carbohydrate use during physical activity. When projected over a standard training week, this shift accounts for an additional 15 to 20 grams of fat burned rather than stored.

Dr. Matthew Cook, lead author and senior lecturer at the University of Worcester, notes that the metabolic effects are particularly pronounced in specific demographics. Individuals with higher body fat mass and those who are more carbohydrate-dependent during exercise show the most substantial gains, with some women experiencing fat oxidation increases of up to 200%. Unlike stimulant-based supplements, the extract functions by up-regulating genes responsible for energy expenditure and promoting the use of intramuscular triglycerides.

For endurance athletes, the data suggests improved glycogen preservation and stronger late-race performance. For the general public, the findings offer a non-stimulant pathway to support fat-max training intensities. As the market sees a rise in imitation blackcurrant products, the researchers emphasize that these clinical outcomes are specific to the standardized Enzans-certified formulation used in the peer-reviewed trials.
