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.

Why has the packaging changed?

We're excited to introduce new packaging as part of our redesign, but you might still see our previous packaging in your orders as we prioritise reducing waste. Rest assured, it's the same high-quality product.
