IMPROVES ATHLETIC PERFORMANCE
A number of clinical studies have demonstrated New Zealand blackcurrant can improve athletic performance. For example, taking blackcurrant before exercise resulted in faster cycling times (Murphy et al. 2017), race times (Cook et al. 2015), and increased endurance during repetitive sprints (Willems et al. 2016) and rock climbing (Potter et al. 2018). Many different mechanisms have been investigated including cardiovascular, anti-inflammatory, oxidative stress management, and metabolic improvements.

A few clinical studies have shown that blackcurrant extract can improve human cognitive function and the inhibition of monoamine oxidase-B and increased monoamine neurotransmitters appears to play a role. Another study demonstrates that blackcurrant may improve self-motivation to adhere to an exercise regime (Lomiwes et al. 2019).

Clinical evidence shows that blackcurrant extract can improve blood flow. It can lower systolic, diastolic, and mean arterial blood pressure; increase cardiac output and stroke volume; decrease total peripheral resistance; increase the diameter of the femoral artery (Cook et al. 2017a); maintain forearm blood flow (Barnes et al. 2018; Matsumoto et al. 2005); and increase circulation in the cold (Takenami et al. 2004). It also has benefits for heart rate (Potter et al. 2018).

www.doi.org/10.1007/s00421-019-04226-2SUPPORTS IMMUNITY
New Zealand blackcurrants have been shown to activate the body’s immune defenses. In one study, New Zealand blackcurrant increased circulating neutrophils, the expression of neutrophil surface receptors, and helped maintain the ability of the neutrophils to phagocytose infectious bacteria (Hurst et al. 2019). In another study, 5-weeks supplementation with blackcurrant extract increased levels of IL-10, which was correlated with enhanced antioxidant status (Hurst et al. 2020).

The specific health effect proposed for New Zealand blackcurrant is the management of moderate exercise-induced oxidative stress and inflammation which leads to improved exercise recovery. A number of clinical trials have also demonstrated blackcurrant extract can reduce measures of muscle damage and fatigue like creatine kinase and lactate (Hutchison et al. 2016; Willems et al. 2015; Lyall et al. 2009).

www.doi.org/10.3389/fnut.2020.00016Manages Inflammation for Tissue Repair
A number of studies show blackcurrant extract speeds the body’s own inflammatory defences toward tissue repair. For example, it appropriately modulates the production of pro and anti-inflammatory or immunomodulatory cytokines like TNF-alpha, IL-6, and IL-10.

www.doi.org/10.3389/fnut.2020.00016IMPROVES FAT OXIDATION
Clinical evidence suggests blackcurrant extract can improve energy usage, especially during exercise. This includes increased fatty acid oxidation, decreased carbohydrate oxidation (Cook et al. 2017b; Strauss et al. 2018), and lower resting energy expenditure (Strauss et al. 2018).

www.doi.org/10.1007/s00421-018-3858-3SUPPORT TRAINING ADAPTATION
New Zealand blackcurrants don’t act as antioxidants in human plasma (Hurst et al. 2019). The management of exercise oxidative stress and inflammation is unlikely to be attributable to the antioxidant properties of the extract and more likely due to blackcurrant activating adaptive defensive pathways in cells and tissues. This potentially occurs through blackcurrant anthocyanins working with exercise to modulate Nrf2-antioxidant response element signalling pathways. Additionally daily consumption of New Zealand blackcurrants over 5 weeks either maintained or enhanced exercise recovery effectiveness, improving anti-inflammatory and immunity measures (Hurst et al. 2020).

A Unique Berry
New Zealand blackcurrants aren’t just any other berry. This powerful polyphenol superfood delivers enhanced performance and faster recovery thanks to a unique and one-of-a-kind combination of anthocyanins that can’t be found anywhere else in the world.
Adaptive Anthocyanins
New Zealand blackcurrants act as a pre-exercise primer to increase plasma oxidative capacity. This triggers your body’s antioxidant and inflammatory defense and recovery systems, so you’re ready to go as soon as your workout begins.
Delphinidins (Pro-oxidant)
Pro-oxidants in 2before switch on your body’s own antioxidant system, helping you to push harder for longer. Taking it 30-60 minutes before exercise helps you reach maximum saturation for optimum cellular priming.
Cyanidins (Anti-Oxidant)
On their own, antioxidants don’t help exercise or recovery —but our unique blackcurrant variety combines antioxidants with pro oxidants, unlocking your extra performance.
