The CurraNZ recovery research, explained

on March 09, 2024

CurraNZ offers active people an effective way of assisting recovery and reducing the unwelcome side-effects of exercise – delayed onset muscle soreness aka DOMS.

Exercise-induced muscle damage (EIMD) is accompanied by localised oxidative stress and inflammation, which is associated with DOMS, tissue damage and impaired muscle function.

A British study1 on CurraNZ has shown stark effects on accelerating recovery of muscle function three-fold, reducing soreness by up to 49% and tissue damage 84%, via the blackcurrant anthocyanin’s inherent antioxidant and anti-inflammatory properties.

Using a double-blind, randomised, placebo controlled, parallel design, healthy participants received either 300mg daily of extract (n = 14) or placebo (PLA) (n = 13) for eight days prior to and four days following 60 strenuous concentric and eccentric contractions of the biceps muscle.

Muscle soreness (using a visual analogue scale), maximal voluntary contraction (MVC), range of motion (ROM) and blood creatine kinase (CK) were assessed before and 24, 48, 72 and 96 hours after exercise. Consumption of the CurraNZ extract resulted in faster recovery of muscle function, attenuated muscle soreness by 47% at 24 hours and 49% at 48 hours.

Serum CK concentration at 96 hours highlighted a stark reduction in tissue damage of 84%.

The study concluded that consumption of one capsule of CurraNZ prior to and following a bout of strenuous resistance training exercise to be helpful for active individuals who are perhaps not used to such tasks, as well as potentially athletic populations.

Other trials2,3,4 have shown that one dose delivers benefits to recovery, but the effects are sustained over time with repeated intake.

In a five-week study3, scientists found that daily consumption of blackcurrant extract in dosing ranges of 1-2 capsules of CurraNZ either maintained or enhanced exercise recovery effectiveness, by improving anti-inflammatory and immunity markers.  

These findings further prove that CurraNZ helps prime cells for the inevitable inflammation and oxidative stress that occurs following strenuous exercise.
