With so many protein powders on the market, isnt it obvious that the most effective option for serious cyclists would be a high-quality whey protein isolate, but why do so many riders still opt for lower quality options. Is it a cost issue, lack of knowledge or just plain old ignorance. Is it possible that road cyclists who focus on long slow miles dont require the benefits that whey protein isolate has to offer and thats why they tend to stick with other types of protein. Does the fact that whey protein isolate can support muscle growth, aid in muscle recovery, and boost antioxidant defenses give it an unfair advantage over other types of protein. Are riders who choose whey protein isolate getting an unfair advantage over riders who choose other types of protein, should governing bodies step in and regulate protein intake in professional cycling.
