Whey protein powder comes in three forms; concentrate, isolates and hydrolysates. Isolates is whey’s purest form containing about 90% pure protein and virtually no lactose or fat. It is sometimes flavored and most commonly consumed by dissolving in milk or water to drink.
Whey protein powder is the best source of the natural branched chain amino acids; leucine , isoleucine , and valine that are so important to athletes. The branched chain amino acids are central to fighting fatigue and aiding in recovery during and after exercise. They are burned at higher levels by active bodies, thus requiring athletes and bodybuilders to consume more of them.
Lactose, or milk sugar, is an ingredient found in many cheaper whey protein concentrates. In fact only whey protein isolates are allowed to claim lactose free status. This is a big reason why whey isolates are so much easier to digest, as many people lack the enzyme needed to effectively digest lactose. Interestingly, even if you don't consider yourself to be lactose intolerant, this disorder often goes unrecognized and can be the cause of many nagging health concerns. So, if you've ever experienced bloating or gas with a whey protein product, chances are it contained lower quality concentrates with substantial amounts of lactose.
Although protein powders may be derived from only one food source of protein, many combine the benefits of several sources, enhancing their overall benefit to the body system. Protein powder regimens and blends usually target specific metabolic purposes or pathways, such as energy production, fat utilization or digestion; or physical activity such as intense exercise, weightlifting or distance running. Certain protein powders are better than others at encouraging healing and trauma recovery, and all protein powders digest and absorb differently into the body. Protein unused by the body is excreted as waste. Protein powders in the U.S. are sold without FDA approval of safety or effectiveness. One downside to efficacy is that some nutritionists insist that an increase in muscle mass resulting from the use of protein powder over time may just be muscles retaining water - with a prolonged regimen sustaining these results. On the upside: protein powder supplementation may indeed build muscle mass, improve endurance and benefit a healthy immune system
