Protein is one of the essential macronutrients your body needs to function.
Athletes, fitness enthusiasts, and people interested in optimizing and maintaining their physical condition prioritize protein in their diet.
For others, eating an adequate amount of high quality protein may be difficult, especially if consuming a standard American diet.
This is where a product such as whey protein comes in.
Whey protein offers many health benefits and is an easy way to increase your protein. Low in fat and low in lactose, whey protein contains all essential amino acids necessary for human health. One serving of whey protein typically contains 20-30 grams of protein and delivers almost 50% of the USRDA for protein requirements of an average-sized man.
Whey protein is a superior source of protein and is derived from milk.
Whey is developed as a by-product of the cheese manufacturing process, and has become a popular way for millions of people across the world to supplement their protein intake.
Is Whey Protein Isolate the same as Whey Powder?
Whey protein isolate is a liquid by-product of the cheese or yogurt-making process that is then processed into whey protein powder. In this form, it is typically used as an additive in sauces, dressings, baked goods, and, most importantly, as a supplement by people who wish to increase their protein intake.
Whey protein isolate is simply a highly purified version of whey protein.
If you wish to get the maximum amount of protein per scoop possible or perhaps wish to avoid lactose due to intolerance issues, whey protein isolate is the best choice.
It is produced by putting whey protein through a filtration process known as Cross-Flow Micro-Filtration. This process removes any additional carbohydrates, cholesterol, fat, and lactose from the whey protein. What we are left with is a powder that contains a much higher concentration of protein.
The Benefits of Whey Protein Isolate
Contrary to what most people assume, protein powders are not exclusively beneficial for bodybuilders.
Anyone who wants to keep their body running optimally can benefit by adding protein supplements to their diet, especially in the form of whey protein isolate. Below are four important ways whey protein isolate benefits the human body:
Whey protein isolate contains high levels of Leucine, an essential amino acid. It works by signaling muscle protein synthesis in the body and works very rapidly as one will find raised blood amino acid concentrations shortly after taking it. This process is responsible for building lean muscle mass, which is responsible for building a person’s strength.
It’s great for weight Loss
It might come as a surprise to learn that supplementing protein in one’s diet can be an effective way to promote weight loss, but it’s true. Whey protein isolate will help you shed weight by giving you a source of protein that does not come with additional calories, fat, carbohydrates, or sugar. Aside from giving you the nutrients you need, it will also help keep you full, allowing you to stick to your weight loss journey more easily.
Builds lean mass
Branched-Chain Amino Acids (isoleucine, valine, and leucine) are essential amino acids responsible for stimulating the rate of muscle protein synthesis processes in our bodies as well as inhibiting the rate of protein degradation. When exercising, BCAAs are burned up quickly (protein degradation and oxidation).
Taking whey protein isolate gives our bodies the chance to restore this balance so that our protein expenditure does not overtake our protein synthesis rate. The ramification of this is that instead of potentially losing lean muscle mass, we will gain it.
Optimal training involves being able to quickly and efficiently recover from a training session. This will allow you to get more training done, and this increased volume translates to greater benefits.
Ingesting whey protein isolate as you prepare for a session, during, or after it will stimulate protein synthesis while simultaneously inhibiting protein breakdown (proteolysis). These are the two processes most directly involved in muscle recovery. Whey protein isolate also contains high levels of L-Glutamine, a conditionally essential amino acid that helps mitigate exercise-induced soreness in muscles.
Which is Better; Whey Protein or Whey Isolate?
While whey protein and whey protein isolate might be considered more or less the same by a casual observer, the reality is that not all protein supplements are created equal. You will find that there are tangible differences in absorption rates, quality, and nutritional content between whey protein and whey protein isolate.
If your goal is to increase lean muscle mass and strength, then whey protein isolate will be your best choice. This is because whey protein isolate has significantly higher concentrations of branched-chain amino acids and has a rapid absorption rate in the body. Those hoping to lose weight will also be better served by whey protein isolate, as it is free of fat, cholesterol, carbohydrates, sugar, and lactose.
For those who take their protein supplement intake seriously, a great product to add to your regimen is Z Natural Foods Organic Grass-fed Whey Protein Isolate, which is cold-processed from the undenatured milk of cows raised in the United States of America.
Containing 90% protein per scoop, it can serve as a valuable partner as you make your way along the road to increased strength, lean muscle mass, weight loss, or general physical wellbeing.
