What Are The Benefits of Whey Protein Powder?

Taking whey protein powder, either as whey protein concentrate or isolate, can have a number of powerful effects on the body. Whey protein powder is highly accessible, affordable and is a useful tool for promoting a high-protein diet.

Whey protein has been studied rigorously and has been found to promote muscle growth, facilitate recovery, and may assist in fat loss by increasing satiety.

Benefits: Protein Synthesis

If you are involved in regular training, there should be an even greater emphasis on ingesting ample protein. During physical training, the muscles are exposed to a great deal of mechanical load which causes small muscle fiber tears. To allow the tears to be repaired and for an efficient muscle rebuild, a process known as muscle protein synthesis (MPS) must occur with the help of essential amino acids along with fat and carbs.

To optimize MPS, a high amount of protein is required. Failing to consume enough will hinder MPS thus potentially stunting recovery and leading to restricted movement, prolonged soreness, and muscular weakness. On the other hand, hitting your daily protein target will facilitate efficient recovery and cause these tears to be repaired rapidly and protein powder can really help. As a result of this process, the muscles fibers will increase in size and strength.

The research is clear, protein supplementation is an effective method of increasing one’s daily protein intake, enhancing MPS and therefore contributes to an increase in muscular strength and size (1). Based on this research, a number of health and fitness businesses have created protein powders. Protein shakes are undoubtedly quick, easy and effective but due to the vast number of products available, it can often be confusing and challenging to pick the right supplement for your needs and goals.

Protein Dosage Recommendations for Optimizing MPS

The amount of protein one should consume daily depends on their physical characteristics and goals. The recommendation for an adult is to consume 0.8 grams of protein per kilogram of bodyweight (2).  However, if you are aiming to build significant muscle mass, it may be necessary to consume more – the recommendation is between 1.0 – 1.6 grams of protein per kilogram of bodyweight. The purpose of this, as mentioned previously, is to advance the rate of MPS and therefore a protein powder can assist with.

The Difference Between Whey Isolate and Concentrate

Furthermore, you may come across terms such as whey “isolate” and “concentrate”. These terms simply refer to a specific stage in the processing of protein. In order to create protein powders, milk is heated to separate curds and whey. The whey protein concentrate is simply whey in its truest form. To create the isolate form, the whey must then be heavily filtered. This is done for one of two sole purposes – to increase the protein percentage of the powder and also lower the carbohydrate and fat content, as well as increasing branch chain amino acids.

Whether you go for whey concentrate or isolate protein powder, it appears to makes very little difference – both are effective. However, if you are looking to maintain muscle size while dropping body fat, whey isolate is one superb option as it has a higher protein content than and is lower in carbs and calories than concentrate. Additionally, if you are lactose intolerant, isolate may be digested more efficiently than concentrate for a post workout (3).

Whey and Casein’s Impact on Muscle Growth

There are different types of protein powder that can be purchased and the two most common types are whey and casein, both of which are animal proteins. In simple terms, whey is a fast digesting protein which causes rapid protein synthesis whereas casein is a slow digesting protein which maintains steady protein synthesis (4). The general understanding is that whey is one of the most effective reasons for building muscle whereas casein is most useful for maintaining muscle size.

Plant and Animal Proteins Impact Muscle Building

There are a number of plant-based protein powders available which are excellent choices for vegans and vegetarians however, be aware that they may not have as profound an impact on muscle building as animal proteins. This is because plant products have a smaller range of amino acids (the “building blocks” of protein) and will, therefore, fail to maximize muscle size and recovery in the same way animal proteins do (5).

Moreover, there has been a great deal of research completed on one of the essential amino acids and one of the key branch chain amino acids known as Leucine which has been found to have a major impact on muscular growth. Whey protein naturally has a high amount of leucine with each serving whereas vegan protein tends to be much lower in leucine.

Best Time To Take A Protein Powder

While it is debated as to the best time to take a protein supplement, it is best to consume 15-60 minutes after you finish your workout. Some suggestions hint that you can take a protein supplement up to two hours after and still see benefits. It is best to take as close to after your workout as possible to get the most out of your training.

How We Decide the Best

Differentiating the differences between protein powders is an arduous task. While certain characteristics of certain powders have been highlighted, it’s important to recognize that these are not necessarily positives or negatives. Rather, it’s a case of simply highlighting methods, ingredients and processes involved in case they cause a degree of difficulty for you.

To decide which protein powders made the list, we considered a number of areas. Firstly, we considered how the powder itself was manufactured to ensure it has been tested, is safe and is a product of premium quality. Secondly, we assessed the ingredients to ensure that each shake contained a high dosage of protein – whether that be whey, casein or a blend of both. Lastly, we considered the palatability and digestibility of each product.

FAQ Section

What is the best protein powder?

Performance Lab SPORT Protein. This powder is a great brown rice protein designed for growth and weight loss. It is much cleaner than many on the market and has potential to really boost your gains. With 20g protein and 100 calories, this is an awesome powder for bulking or cutting.

Which type of whey is better for my gains?

It all depends on what your goals are. In terms of bulking up, whey concentrate is a better option given that it has carbs and fat along with the high amount of protein. For those looking to lose weight, a whey isolate is a better option given that it is a more pure form of protein with minimal to no carbs and fats. It really all depends on your preference and what you want out of your goals.

How do vegan protein powders stack up against whey protein powders?

Vegan protein powders stack up well against whey by providing you with great amounts of protein and other ingredients to aid in training, performance, health, and wellness. For those sensitive to dairy, vegan options are great for your gains.

When is the best time to take a protein supplement?

It is best to take a protein supplement in the window of 15-60 minutes after you finish a workout. This will ensure your body has time to absorb all of those nutrients to aid in growth and recovery.

Final Word

While these 8 products are of supreme quality, they will ultimately fail to cause changes if two other factors are not taken into account – consistent resistance training and a calorie surplus. You should not expect to see an increase in muscle mass by simply taking a protein powder. Muscle strength and size will only occur when this is combined with regular strength training and is one of the key reasons for the best whey protein powder for your post workout needs.

In addition to this, a calorie surplus is also required. This is simply where you consume more calories per day than your body requires. The additional energy is necessary to promote recovery from the stresses of strength training and consequently drive an increase in muscle mass. Only with a combination of proper training, a calorie surplus and a high-protein diet and whole foods, will you begin to see substantial change take place from a great protein source.
