Product Description
New Zealand Blackcurrant Extract Supplement for Endurance Performance & Heat Training
Here's what most athletes don't realize: when you train hard in the heat, blood flow gets redirected away from your gut to help regulate your body temperature. The result? Cramping, nausea, or worse. Studies show 90% of endurance athletes experience heat-induced GI distress. If you've ever had to deal with this mid-training or on race day, you know how fast it can derail months of preparation.
CurraNZ Original is the most researched blackcurrant supplement in the world, backed by 60+ peer-reviewed studies proving it protects your gut, accelerates recovery, and boosts performance.
Eliminates Heat-Induced Gut Issues One study showed that 92% of runners experienced GI symptoms with a placebo, but only 25% had issues after taking CurraNZ for seven days. That's a 67% reduction in the gut distress that kills training sessions and races.
Speeds Recovery by Up to 45% The anthocyanins in New Zealand blackcurrants increase blood flow to working muscles by up to 45%, helping clear lactate faster and reduce muscle damage. Elite trail runners like Ruth Croft and 2024 UTMB champion Hayden Hawks credit CurraNZ as a key part of their recovery protocol.
Protects Your Gut During Heat Stress CurraNZ reduces intestinal cell damage by 40% and small intestinal permeability by 12% when exercising in hot conditions. No complicated heat acclimation protocols required—just seven days of supplementation.
The science is simple: New Zealand's harsh UV conditions produce blackcurrants with the highest anthocyanin density of any berry. These powerful antioxidants protect the gut lining, improve blood flow, and reduce inflammation. Each capsule delivers 105mg of anthocyanins—the equivalent of a generous handful of fresh blackcurrants—in a concentrated extract that's been clinically proven to work.
Daily Use: Take 1-2 capsules daily for general health and recovery support.
Pre-Workout: Take 1-3 capsules two hours before training or racing. If you weigh over 165 lbs, consider 2-3 capsules. Load for seven days before competition for maximum gut-protective and performance benefits.
Ultra-Distance: For events over six hours, take an additional 1-3 capsules every 4-6 hours.
Pro athletes across trail running, cycling, and triathlon have been quietly using this for years. This isn't just another berry supplement. This is your secret weapon against the gut issues and recovery gaps that separate good performances from great ones.

CurraNZ Original FAQ's
Everything you need to know before getting started.
When you exercise in heat, blood flow diverts from your gut to help cool you down, causing damage to your intestinal lining.

Most athletes notice improved blood flow and reduced muscle soreness within 1-4 days of daily use. For maximum gut-protective benefits during heat training, load with 1-2 capsules daily for seven days before your event or hot weather training block.
