curranz
Mark Willems (University of Chichester) has published some research papers recently showing CURRANZ blackcurrant capsules do the following:
- Ability to burn more fat Participants showed increases of up to 27% at moderate cycling intensity, and 15% at low intensity
- Reduced carbohydrate demand Participants used 11.5% less carbohydrate
- Ability to tolerate higher lactate Participants had elevated lactate values, meaning they could exercise harder before tiring

My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter — the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session.
- Ravemen FR300 — front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters.
- Garmin Varia RTL515 — radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd — the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
- Favero Assioma Pro RS2 — the power meter pedals most serious cyclists end up choosing. Accurate, easy to move between bikes.

Interesting, thanks for the link to the study as I hadn’t come across this supplement before. From a performance point of view it looks quite interesting used as a “race day” supplement due to the fact there doesn’t appear to be an effect on Lactate at the lower VO2max workouts, but a relatively large (for longer events) effect during a time trial.
The higher fat % use from training is interesting to observe as well, could be useful in January for burning off the excess turkey 🙂
yes – it is often hard to quantify to yourself if it has helped – I trust it to do something (took before my TRI PB…did it help???maybe). if you try it as part of training (before hard training) I find you rarely ache the next day(s) ie def aids recovery – which if you are doing 10+ hours a week should be important to you IMO
Yes I fall into the 10+ hours a week, following a Polarised training plan for rowing so would certainly be nice to have something to help recover from the HIIT sessions!
