  • Regeneration after the workout: recovery and regeneration are extremely important aspects of successful training. This applies equally to beginners and advanced athletes. Between the training sessions, the body needs rest periods to repair the strained structures and to adapt to the training stimuli. During regeneration, it is important to ensure a full diet, including high-quality protein, to support the body's own processes
  • Multi-component formulation: Depending on the flavor, the Protein 80 Plus provides up to 34 g of protein (mixed with low-fat milk, 1.5%) from four different protein sources: casein, milk protein isolate, whey protein and chicken egg protein. The high-quality protein sources contain a high proportion of essential amino acids and contribute to the maintenance and building of muscle mass *. In addition, the WEIDER Protein 80 Plus contains Vitamin B6 to support normal protein metabolism
  • Versatile: Our Protein 80 Plus can be prepared in different ways. The low-fat powder dissolves perfectly in water and low-fat milk and can also be mixed with other drinks. Protein 80 Plus can also be used as an ingredient in cooking and baking (for example for protein-rich porridge or pancakes).
