I have been taking CurraNZ for just over three months and I have noticed a remarkable change in my energy levels and stamina. I run 5-6 days a week and have on occasions suffered from shin splints. Since taking CurraNZ, I have increased each run from 4K to 5k and have not been troubled by shin splints. I have also noticed a difference mentally, like a fog has been lifted. I think more clearly and feel much more alert and open to ideas. I generally feel a lot better in myself and I am channeling this into both my daily run and business. The subscription program is extremely efficient so I never run out. As an added bonus, there is also a 10% saving on the price. Great service, great product. I can definitely recommend CurraNZ
