WPI protein is one of the fastest ways to build and repair muscles after training. We all know that protein is an essential building block for muscles, but how do you know what type you should be consuming to help you recoup muscles? Whenever it comes to supplements, the quicker you can get your body the protein it needs, the better. So here is a look at why WPI is one of the fastest ways to recoup and repair muscles.

What is WPI? 

Whey Protein Isolate is one of the most popular protein supplements today. However, while the term "whey protein" has been a staple in bodybuilding circles for decades, it was not until the early 1990s that whey protein isolate became available to the public. Whey protein isolate is more than just a fancy name given to a new type of protein; it's an entirely different form of protein that offers certain advantages over other types of whey and other forms of protein. The difference between whey protein isolate and concentrate is significant enough to dedicate an entire article to explain these differences. Still, in summary, whey protein isolates are purer than concentrates because they contain less fat, lactose, and other non-protein elements. One of the reasons whey isolates is so popular with athletes, dieters and fitness enthusiasts is because it contains up to 90% pure protein with little or no fat or lactose.

How WPI Helps with Muscle Recovery 

The most common cause of muscle soreness is microscopic damage to your muscle fibres during exercise. Delayed onset muscle soreness (DOMS) typically occurs 12 to 24 hours after your workout and can last up to a week or longer. DOMS results from an inflammatory response in the body, which helps repair damaged muscle tissue. This inflammation can be reduced by taking WPI supplements, helping you recover more quickly from a hard workout. Research shows that supplementing with WPI reduces DOMS compared to other types of protein, including casein, soy, and whole milk protein. It has been found that whey protein isolates reduce muscle damage, improve performance and decrease fatigue when taken before and after exercise. The mechanism by which WPI reduces oxidative stress, inflammation, and muscle damage following eccentric exercise can be explained by three possible means: 

1) WPI reduces pro-inflammatory cytokine synthesis 

2) WPI promotes anti-inflammatory cytokine synthesis 

3) WPI acts as an antioxidant. 

Due to these mechanisms of action, the dietary supplement whey protein isolate (WPI) has been proven to be useful in reducing muscle recovery time. This review discusses the mechanism of action of WPI on skeletal muscle in an effort to explain how WPI reduces muscle recovery time. The reduction of muscle recovery time is related to the reduction in oxidative stress, inflammation, and/or muscle damage following eccentric exercise.

Other benefits of WPI 

Here are four science-based health benefits of whey protein: 

WPI Can Help You Lose Weight While Preserving Muscle Mass 

The main benefit of whey isolate is that it can help you lose weight while still preserving lean muscle tissue. The body needs protein to build muscle — when you don't get enough from your diet, the body will start breaking down existing muscle tissue to obtain more. This can lead to muscle loss, which slows down your metabolism over time because muscle burns more calories per pound than fat does. Whey isolate supplements provide a convenient source of additional protein, which can help prevent this problem. 

Whey Protein Isolate Promotes Muscle Gain in People with Low Protein Intake 

Whey protein isolate is a good quality protein source that promotes muscle gain and fat loss. It's particularly beneficial for people with a low protein intake. Whey concentrate may contain anywhere from 35–80% protein, whereas whey isolate is 90% protein or higher. Therefore, it's much lower in fat, carbs, and lactose (milk sugar) than whey concentrate. In addition to its high percentage of pure protein, whey isolate goes through additional processing to remove even more fat and carbohydrates. For this reason, it tends to be more expensive than other forms of whey.

WPI Increases Muscle Strength and Improves Endurance 

WPI is rich in the amino acid leucine, which plays an important role in muscle building. Leucine activates a signal within your body that stimulates muscle synthesis, which is the process of creating new muscle proteins. When muscle synthesis is increased, your muscles grow stronger and larger. This leads to increased power during high-intensity exercise. 

Whey Protein Isolate May Reduce Hunger and Aid Weight Loss 

Whey protein isolate may help you feel full for longer and help you consume fewer calories each day, thus helping you achieve or maintain a healthy weight. When it comes to recovering after a hard workout, you want to make sure that you maximize your results. The most effective way to do this is by supplementing your diet with protein. And while there are many options on the market, WPI offers the best overall muscle recovery and boost in performance.

Reduces pro-inflammatory cytokine synthesis, Promotes anti-inflammatory cytokine synthesis, and Acts as an antioxidant are some of the benefits of WPI Protein.
