Our Packaging

We've gone through an exciting redesign, and as we step into a new era, you'll see fresh packaging in your orders. Change is a good thing. But change takes time. Especially when you make change responsibly.

Because we don't believe in wasting perfectly good packaging - that would go against our sustainability pledge - you might get a mix of old and new designs inside your orders.

Rest assured, it's still the same consistently high-quality product, just as you'd expect. If you happen to receive classic packaging, know that your order is helping to reduce waste. And if you receive anything with a fresh look, you're one of the first, and we'd love to hear what you think. 
Thank you for joining us on our journey to reduce our impact on the planet, while maximising our impact for our community.

1. Protein contributes to the growth and maintenance of muscle mass.

2. Carbohydrates contribute to the recovery of normal muscle function (contraction) after highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle. This beneficial effect is obtained with the consumption of carbohydrates, from all sources, at a total intake of 4g per kg body weight, at doses, within the first 4 hours, and no later than 6 hours, following highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle.
