'I have now been taking CurraNZ for a couple months through some of the hardest training weeks I have done as I train for Western States 100. I have never felt better, can handle the training load a lot easier, and am seeing improvements in my recovery and performance. CurraNZ works and I am excited to continue with this product as I tackle some of the biggest Ultras in the world!'
'Training on CurraNZ definitely helps with recovery. If you're a runner and don't have an everyday supplement for training, racing, recovery or energy, I highly recommend CurraNZ. Plus, it's backed by lots of great research too'
'I took it for a test run! I did the Milford Track (60km and 9hrs of running) in one go on legs that were definitely not trained for that distance/time. I had taken CurraNZ for about a month before I did the run, and was so surprised at how my legs responded to the fatigue of the run, as well as recovering quickly without any DOMS!'
'My recovery phase (of hard training) matched the science/study results of faster recovery with less muscle soreness. The Anthocyanins have been studied to improve natural blood flow (read: recovery+ & performance+) so I’m excited to say I was feeling really solid through these sessions! #NewFan'
'After a recommendation from a trusted elite running friend I started using CurraNZ and have been able to increase the intensity of my sessions. Since then I have set new PBs for every distance from 5,000m to marathon and have been getting faster in my 40s. For the first time ever, the product has allowed me to go on training runs the days following a marathon. The reduced DOMS is really significant - my running mates have been amazed that can run the day after a race. I put it down to CurraNZ.'
'I’ve seen big differences from year to year using CurraNZ. I train my body through the full spectrum - slow energy training, tempo work, threshold stuff, VO2max – and I’m more efficient at every level of output.“Everything has moved on - even my coach has been taken aback. In my last track session I was 5 seconds per kilometre faster and my maximum heart rate was seven beats lower. “That’s significant and adds up to a lot of improvement and at a lower cost too. I’ll happily attribute that to CurraNZ’s vasodilatory action and creating less resistance to help blood and oxygen delivery - it all stacks up.“CurraNZ is the only supplement I use and has been a game changer.'
'CurraNZ helped me get into the greatest shape ever at the age of 43. The supplement’s endurance, fuelling and recovery benefits have been crucial for a long-distance athlete like me.'
'The feedback from my footballers has been positive, as an example, athletes who are experiencing overtraining syndrome have found that it’s disappeared within a week of using CurraNZ.'We use CurraNZ for recovery during intense periods and also pre-exercise, because of the improvements it delivers to blood flow.'
