If you’re someone who regularly exercises, you’ve probably experimented with supplements designed to enhance performance — things like creatine, protein powders, and pre-workouts. But recently, attention has shifted toward natural, whole-food options that may also boost athletic abilities.
Among these, blackcurrants — especially those grown in New Zealand’s nutrient-rich soil — are emerging as a powerful, natural performance enhancer.
Blackcurrants are rich in antioxidants, notably anthocyanins, the compounds responsible for their deep purple color. These anthocyanins promote vasodilation, or the widening of blood vessels, which improves blood flow — a key factor not only for athletic performance but also for overall health, including conditions like erectile dysfunction.
Research tracking over 25,000 men for ten years found those eating anthocyanin-rich berries, such as blackcurrants, had a 19% lower risk of erectile dysfunction.
Beyond general health benefits, multiple recent studies have highlighted blackcurrant extract’s specific performance advantages:
1. Enhanced Athletic Performance:
A study published in Nutrients revealed that taking a seven-day supplementation of 600mg New Zealand blackcurrant extract (CurraNZ) improved running distances by an average of 8%, with some individuals showing up to a 38% increase during intense treadmill efforts.
Cyclists also saw a notable improvement, cutting 44 seconds off a 16.1 km time trial after the same supplementation period. A 2020 meta-analysis of 16 studies confirmed blackcurrant’s positive effects on sports performance without harmful side effects.
2. Improved Recovery:
Blackcurrants’ antioxidant properties help reduce exercise-induced inflammation and oxidative stress. Trials have shown that blackcurrant extract lessens muscle damage and enhances recovery following intense resistance exercise.
Another study found that taking the extract before rowing reduced oxidative stress and preserved key immune cells involved in inflammation control. Extended supplementation further boosts these recovery benefits.
3. Reduced Exercise-Induced Gastrointestinal Symptoms:
Exercising in heat can cause uncomfortable GI issues like stitches and bloating. A recent study found that seven days of blackcurrant extract supplementation dramatically lowered the incidence of these symptoms during a one-hour run in hot, humid conditions—from 92% experiencing symptoms on placebo down to 25% with the extract.
Conclusion:
While more extensive research is needed to fully confirm these benefits across diverse populations and to refine dosage guidelines, the current evidence strongly supports blackcurrant extract as a natural and effective aid for enhancing performance, speeding recovery, and reducing heat-related GI distress.
Given its antioxidant and anti-inflammatory powers, blackcurrant extract is a promising supplement for athletes and fitness enthusiasts alike. As always, consult a healthcare professional before adding new supplements to your routine.
