Most people exercise hoping to shift a few extra pounds. Research increasingly confirms that what you take before exercise matters just as much as the effort - and clinically researched New Zealand blackcurrant extract, the active ingredient in CurraNZ, is proving its credentials.
What the Latest Research Found

A recent clinical study published in the International Journal of Sport Nutrition and Exercise Metabolism found that CurraNZ can increase fat burning during exercise by up to 200%, with an average increase of 28% across 90% of participants.
Women with higher body fat levels saw the most dramatic results - up to 216% more fat burned.
This study wasn't the first to show its powerful fat-burning effects, in fact over a dozen studies have confirmed this.
After just seven days, participants burned an average of 3.6 grams of extra fat per hour of exercise. Over a month of exercising five times a week, that adds up to roughly 72 grams of additional fat - around five tablespoons of butter.
Lead researcher Dr Matthew Cook called it “a watershed moment” in New Zealand blackcurrant extract research.
He also noted a meaningful cardiovascular benefit: blood pressure dropped by up to 11% following exercise - reductions “comparable to what a doctor would seek to achieve through prescribing blood pressure medications.”
A Natural Alternative Worth Knowing About
Conversations around weight management increasingly centre on prescription drugs like Ozempic.
CurraNZ offers a different path: no prescription, no injections, no side effects, and at a fraction of the cost. It works by supporting your body’s natural fat-burning processes - not by overriding them.

Keep Going
The science is encouraging, but consistency is what turns results into real-world change. If you’re near the end of your current supply, now is a good time to stock up and keep that momentum going.
