Is this porridge suitable for people who do sport, or is it just an ordinary breakfast? — Quick Protein Oats – Apple-Cinnamon, 1 kg – ICONFIT

This is a food product (a porridge mix), not a sports supplement. According to the manufacturer's description, it contains about 30% protein, fibre and more than 10% hydrolysed collagen, and no added sugar; these figures may be useful for people who keep track of the amount of protein in their diet. The product card gives no recommendations for taking it before or after workouts and no data on its effect on athletic performance.

General remark (not a manufacturer's instruction): for specific sporting goals (gaining mass, losing weight), such porridge is better viewed as part of the overall diet rather than as a stand-alone solution; for questions about nutrition, it is better to consult a specialist.
