What's behind it
According to Optimum Nutrition, Serious Mass is intended for people with a high metabolism, a small appetite or a busy life on the go who find it hard to take in enough calories from solid food.
What creatine, protein and carbohydrates do
- Creatine increases physical performance in successive bursts of short-term, high-intensity exercise. The beneficial effect is obtained with a daily intake of 3 g of creatine. The claim applies to adults over 18 years of age who perform high-intensity training.
- Protein contributes to a growth in muscle mass.
- Protein contributes to the maintenance of muscle mass.
- Protein contributes to the maintenance of normal bones.
- 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. The beneficial effect is obtained with a total carbohydrate intake of 4 g per kg of body weight, within the first 4 to 6 hours.
