August 10, 2023

As the popularity of health and fitness continues to skyrocket, so does the demand for reliable, effective supplements that can support our fitness journey. One of the most well-known and researched of these supplements is whey protein. But what is whey protein, and how is it made? This comprehensive guide will take you through everything you need to know about this vital supplement.

The Whey Protein Market Size

The whey protein market is more significant than ever, with individuals from all walks of life incorporating it into their diets. From bodybuilders and athletes to everyday fitness enthusiasts, the benefits of whey protein have been recognized and capitalized on worldwide. According to a report by Grand View Research, the global whey protein market size was valued at USD 10.7 billion in 2020 and is expected to grow at a compound annual growth rate (CAGR) of 12.5% from 2021 to 2028. This growth is driven by the increasing awareness of the health benefits associated with the product and its widespread use in various end-use sectors, including food and beverage, dietary supplements, and sports nutrition. But before we dive into what whey protein does, let’s understand what it is.

Understanding Whey Protein

Whey protein is a mixture of proteins isolated from whey, the liquid part of milk that separates during the process of cheese production. It is a high-quality protein, containing all of the essential amino acids needed for muscle recovery and growth. There are three main types of whey protein: Whey Protein Concentrate (WPC), Whey Protein Isolate (WPI), and Whey Protein Hydrolysate (WPH).

Whey Protein Concentrate (WPC): WPC contains low levels of fat and carbohydrates (lactose). The percentage of protein in WPC can range from 30% to 90%, making it a versatile option for those seeking to increase their protein intake.

Whey Protein Isolate (WPI): If you’re wondering what whey isolate is, it’s the purest form of whey protein with the least amount of fat and lactose. It contains 90% or more protein and less lactose, making it an ideal choice for those with lactose intolerance.

Whey Protein Hydrolysate (WPH): also known as hydrolyzed whey protein, is a pre-digested form of whey protein. It is easily absorbed by the body and reduces the risk of potential allergic reactions, making it a suitable choice for those with sensitive digestion.

Each of these forms of whey protein offers its unique advantages and can be chosen based on an individual’s dietary needs, goals, and personal preferences. Now that we know what whey protein is and what it’s made of, let’s move on to how it’s made.

The Whey Protein Manufacturing Process

If you’ve ever wondered, “How is whey protein manufactured?” you’re not alone. It is a complex process that involves a number of steps, each crucial to the final product’s quality and nutritional profile. Here’s a step-by-step breakdown of how whey protein powder is made:

Step 1: Milking

It all begins at dairy farms, where cows are typically milked two to three times daily. The liquid milk produced contains 4 to 6 grams of protein per liter, serving as the initial source of the whey protein we know and love.

Step 2: Transportation

Once collected, the milk is transported by insulated tanker trucks to the whey manufacturing plant. The trucks’ insulation ensures that the raw milk remains cold, preventing spoilage before it reaches the processing plant.

Step 3: Pasteurization

Upon arrival at the plant, the milk goes through pasteurization to eliminate any bacteria. This involves heating the milk to 80 degrees Celsius and then rapidly cooling it down to 4 degrees Celsius.

Step 4: Cheese-Making

The fun part begins here! Whey is derived from the cheese-making process. After the milk passes quality tests, enzymes are added to separate the cheese curd from the liquid whey. The liquid whey is then purified, and the protein is concentrated and isolated. This is achieved via membrane filtration and ion exchange technology, methods that remove fats, carbohydrates, water, and lactose while retaining the protein-rich liquid whey.

Step 5: Drying

Next, the liquid whey is loaded into a dryer, which separates the water from the solid particles through a process involving hot and cold air. The resulting product is a powder composed of up to 90% whey protein.

Step 6: Quality Testing

At this stage, the whey protein powder is tested for purity. If it passes these quality tests, it gets packaged, typically in 25 kg bags.

Step 7: Toll Manufacturing

These bags of unflavored whey protein powder are sent to toll manufacturers for further processing. Here, the raw materials undergo further testing for microorganisms, potency, and other quality parameters to ensure they meet specifications.

Step 8: Flavoring and Mixing

Once the whey protein powder meets the quality specifications, it gets further processed. It’s loaded into high-speed blenders along with other ingredients and flavoring components, depending on the formula of the finished product. Random samples are taken from the batch of finished products and sent to the lab to verify their protein content using an infra-red machine.

Step 9: Final Quality Check and Distribution

If the batch of finished products passes all quality testing, it’s released and shipped to retailers. This is the end product that you typically see and buy from stores. They bear all the nutritional information, product registration with the governing health agency, and are sealed properly to ensure freshness and quality.

So, now when someone asks you, “What is whey protein made of?”, you can impress them with your in-depth knowledge of the manufacturing process, from dairy farm to supplement shelf!

The Benefits of Whey Protein Supplementation

Before delving into the benefits, let’s first understand what does whey protein do. It helps in repairing and building the muscle tissues in our body and according to scientific research conducted by the National Library of Medicine, whey protein supplementation offers a wide range of benefits. From optimizing physical performance to enhancing muscle recovery, the strategic consumption of whey protein can offer a host of benefits to athletes across various sports disciplines. Let’s dive deeper into the science-backed benefits of whey protein supplementation.

1. Enhanced Recovery and Performance

Protein intake around your workout plays a significant role in muscle recovery and performance, particularly for seasoned gym-goers. A study by Morton et al. suggests that the strength effects of post-resistance training protein supplementation are greater in those with previous resistance training experience. This means that seasoned lifters can further amplify their gains by adding whey protein to their post-workout routine.

2. Boosts Lean Body Mass

For those who are in a caloric deficit, resistance-trained individuals require significantly more protein to avoid losing lean body mass. Having a daily protein intake in the range of 2.3–3.1 g/kg FFM is recommended. And, there’s more good news – even during overeating phases, protein showed no negative effects on body composition in trained individuals.

3. Optimal Protein Quality

Whey protein provides the essential amino acids required for protein synthesis, including leucine, a branched-chain amino acid (BCAA) vital for the recovery and adaptive processes following a training bout. Consuming high-quality protein like whey protein ensures you’re getting the necessary nutrients for muscle building and recovery.

4. Facilitates Versatile Athletic Goals:

Whether the goal is muscle hypertrophy, as in bodybuilding, or enhanced recovery for sports and fitness enthusiasts, intake of whey protein, can be a useful tool to help athletes reach their goals.

5. Delays Central Fatigue in Endurance Training:

Although protein consumption during endurance exercise may not provide immediate performance benefits, it can delay central fatigue, reduce muscle protein breakdown, and enhance whole-body nitrogen balance.

6. Boosts Immune System Function:

Consuming protein in and around intense or prolonged endurance activities can reduce the incidence of upper respiratory tract infections and improve immune system function, which is crucial for athletes in training.

7. Promotes Enhanced Resistance Training Outcomes:

Resistance training paired with per-training protein consumption, particularly for those on calorie-restricted diets, can lead to desired improvements in strength, hypertrophy, or the maintenance of fat-free mass (FFM).

8. Convenience for Athletes:

One of the significant benefits of whey protein is its convenience. It is a versatile supplement that can easily be incorporated into a healthy lifestyle. It can be mixed with water, milk or almond milk or your preferred beverage, making it simple to increase protein intake whenever it’s most suitable – be it first thing in the morning, post-workout, or even as a late-night snack. Moreover, its portability allows for a protein boost on the go, ensuring athletes can maintain their nutritional needs irrespective of their location or schedule.

9. Synergistic Nutrient Impact:

Pairing whey protein with carbohydrates and creatine monohydrate can boost your strength and hypertrophy gains. Carbohydrates have a protein-sparing effect, helping to shift total body protein balance towards the anabolic side, which is the state of building up – exactly what you need for enhanced muscle growth and recovery.

10. Extends Recovery Window:

Studies show that consuming 30g of whey protein 30 minutes before sleep resulted in increased resting energy expenditure and improved VO2 the next morning, indicating enhanced recovery.

The Effective Use of Whey Protein Supplements

Proper usage of whey protein supplements can significantly enhance your workout results. While many associate protein supplementation with post-exercise routines, it’s crucial to understand that its timing effects extend to the entire peri-workout period. For instance, consuming a dose of whey protein immediately prior to a resistance training session can also contribute positively to your workout results.

In a study examining the effects of consuming 25 g of hydrolyzed whey protein before a resistance training session versus consuming the same quantity immediately following the same training session, no differences in body composition changes or one-rep max back squat or bench press were found after an 8-week intervention. This suggests that as long as total daily protein intake is adequate, the timing of protein intake might not be as critical as once believed. However, this does not rule out the possibility that pre- and post-exercise supplementation might provide additional benefits depending on the dose.

But remember, the efficacy of whey protein supplementation is not solely determined by timing. Factors such as your daily protein intake, the presence or absence of an energy deficit, and the type of training you undertake play a role in how much benefit you derive from the supplement.

Tips on Choosing the Best Whey Protein Powder

With a myriad of options in the market, choosing the right whey protein powder can seem like a daunting task. Here are a few tips to help you identify the top-selling whey protein powder that best suits your needs:
