This is a quick CURRANZ Review…more of an overview. A Detailed review is linked to below.
The CURRANZ tablets are concentrated blackcurrant juice with which actively uses natural anthocyanin to positively affect blood flow via nitrate oxide synthesis. Blackcurrant positively affects lactate tolerance and substrate oxidation. You take them once daily following a ‘loading’ strategy or pre-race you could have one at least 2 hours before the race.
What does that mean?
It helps you tolerate running harder at higher intensities. It increases the amount of fat you convert into energy – this makes your carb stores last longer (super-important in endurance sport) and 2018 research will show that it increases fat burn (weight loss) when exercising.
Positives: Taking a tablet is pretty straightforward. IMO they definitely and noticeably improve recovery, removing most aching legs the day after a hard session. University research shows noticeably increased performance and in my opinion that MAY be the case with my performances.

Comments: I have integrated these into my race nutrition regime with a 2-3 day loading strategy before the race on the ‘it probably doesn’t hurt’ basis. I also use them at least once weekly immediately prior to my dreaded ‘hard swim’ day. That day is CERTAINLY easier with CURRANZ and BEET-IT combo. I would suggest getting together with a few like-minded athletes to share the cost of a pack before a hard session and see what you all think 24 hours later.
Promotional Discount Code is 5KRUNNER on the curranz website, this should give you 10% off (the manufacturer sometimes offers FIRST TIME buyers a 20% discount when you go to their site). The supplier occasionally sends me free product rather than any monetary payment for the use of this code.
