Why it's important for endurance athletes

Running, cycling, triathlon - long exercise breaks down muscles and flushes out electrolytes faster than regular strength training. Sports recommendations indicate 1.2-1.4 g of protein per kilogram of body weight per day for endurance sports, which is more than for a sedentary lifestyle, but less than for typical mass building.

The problem in practice is simple: after 2-3 hours on the route, hardly anyone wants to cook a full dinner. Hence the demand for ready-made protein products - shakes, creams, bars and powdered meals that can be packed into a backpack or drunk immediately after the finish line.

SUPERSONIC builds an entire directory around this problem: protein shake with collagen for joint and muscle regeneration, creatine for energy, ready-made meals for a quick restart. The 2026 ranking below ranks it by specific use, not just taste or price.

What determines the best protein products for endurance athletes

  • Protein content per serving - the more in a smaller volume, the easier it is to eat after long exercise.
  • Additional regenerative ingredients - collagen for joints, magnesium for cramps, vitamins for immunity.
  • Form and comfort - ready-to-drink liquid versus powder to be mixed in a shaker.
  • Calorie content adjusted to the goal - different needs when reducing, different when building a strength base.
  • Price per portion - the range in this list ranges from PLN 21.40 to PLN 116.
  • Absorption of the active ingredient - mainly concerns creatine and collagen.
