Train your body
from the inside out

Your metabolism builds muscle, provides you energy and repairs damage. Optimising your metabolic fitness means being able to train harder, perform better and recover faster – all while protecting your long-term health.

'Super' for a reason

Sulforaphane is a hugely exciting natural molecule that works to repair & maintain our metabolism. 

It has been shown in clinical trials to support muscle power, endurance and recovery – and to minimize the risk of injury and long-term damage in athletes.

Our super-broccoli is a uniquely powerful source of sulforaphane, making it the best choice for athletes looking to train and optimise their metabolic fitness. 

Enjoy it your way

Simply mix with a shake

Add a scoop to your protein shake for the simplest way to get your super-broccoli boost.

Blend into a smoothie 

Add a scoop to your one of our smoothie recipes to give them an extra super-broccoli kick.

Turn it into a meal

Simple but effective

It mixes in really well with my protein powder - I don't really notice the taste when I'm drinking it, but I've noticed the difference in how I feel, particularly in my knees! Excited to see more clinical trial results.
Makes a difference
Read More
I mix this powder into a smoothie or overnight oats a couple of times a week - it gives it this vibrant green colour that I love, and it's definitely made a difference to how I feel in the mornings!
A bit of a bargain
Read More
I was recommended this powder by a friend - at first I thought it seemed expensive, but compared with supplements or eating a big pile of raw broccoli every day, it's actually a bit of a bargain really.
Tastes great in stews

I'm not a big shake or smoothie drinker, so I tend to mix a scoop of this powder into a stew or sauce instead. That way it adds a great fresh broccoli flavour and I still get my super-broccoli boost!

Made from GRextra

Our patented super-broccoli

Our BrocAffex Powder is pure and simple: just our patented super-broccoli (plus a little mustard powder to maximise bioactivity).

Our unique super-broccoli is unlocking the power of broccoli like never before, to help you gain that extra edge.
