By now I’m sure you must have heard about the different types of whey protein at one point or another along your fitness journey. If you haven’t, or if you aren't sure what the differences are between each type of whey protein, then this article is for you.
Let’s take a look at each of the three types of whey protein (whey concentrate, whey isolate, and whey hydrolysate) and see what each one has to offer everyone from athletes, fitness enthusiasts, and health consensus individuals alike.
THE FUNCTIONS OF PROTEIN
First, let’s recap why protein is so important.
Protein is a major macronutrient, one of the building blocks of muscle, bone, and skin. It aids immune system function, repairs damaged tissues, and supports overall health. To everyone in CrossFit or who workouts at the gym, plays sports, or is involved in regular exercise, protein is much more essential. In fact, according to the British nutrition foundation, strength and endurance athletes need as much as 1.2-2kg/Kg body weight/day (or .54g-.91g/lb. body weight/day) compared to the general adult population that requires 0.75/Kg body weight/day (or.34g/lb. body weight/day).
The reason for this is easy to understand, when you exercise, muscle fibers are broken down and require repair. Protein promotes muscle repair which aids recovery. Protein also boosts glycogen storages, which improves strength and aids performance. If you exercise often but feel like you have low energy or aren’t building enough muscle, you should check your daily protein intake and possibly consider a protein supplement to help you reach your daily protein requirements.
In a study published by the international journal of Sports and Nutrition, the effect of protein supplementation on lean muscle mass was assessed during resistance training, candidates who were giving supplements had greater lean muscle mass than those who had only resistance training. The conclusion made was that protein supplementation offers more benefits in resistance training than resistance training alone.
