What Is Whey Protein Powder? - Good or Bad?

Whey Protein Powder, one of the most popular protein supplements on the market. Many people take it, without knowing the reactions or results that come with the desired supplement. In this article, we will simplify and answer “What Is Whey Protein Powder?” Here is a beginner break down of the capabilities of whey protein powder, but first off…

What is “Whey” Protein?

Whey, as labeled on many protein supplements, is derived from milk. Your milk is made up of two proteins, casein, and whey, both of which can be extracted, during cheese production to be exact, and formulated into their own consumable beneficial products. [Milk is 80% casein and 20% whey (liquid)

Since whey contains all 9 essentials amino acids, it is considered a complete protein. Not only does it contain protein, but it contains other powerful nutrients as well. After extraction from cheese production, and following several other processing steps, it is turned into the whey protein we all know and come to love, used to make protein powders, bars, shakes, etc.

However, taking whey protein comes with a handful of great benefits but also a handful of risks. We will discuss both and give you, the reader, our opinion on the matter. But even before that, we must discuss the different types of whey…

The Three Wise Whey

In the protein supplement world, there are 3 types of whey protein. We will be looking at them individually to see what they got in store. They all offer different attributes that are worth addressing. Their respective abilities may help certain people reach certain goals, while another may be for a broad consumer audience.

Whey Protein Isolate (WPI)

As on the most processed whey proteins, WPI contains the highest amount of protein, ranging at around 90% or higher. The lactose and fat of whey are extracted along with the potential benefits of the nutrients. Not to mention, the flavor is not very tasty, therefore flavors give to the whey which may spark sugar levels.

Ex: Optimum Nutrition Gold Standard Whey Protein

Whey Protein Concentrate (WPC)

Only containing 70%-80% protein, WPC does not contain as much protein as WPI. In exchange, however, WPC does contain more lactose and fat, producing benefits from the nutrients and a much better flavor.

Whey Protein Hydrolysate (WPH)

This whey protein has gone through hydrolysis, making it be considered is predigested, meant for faster absorption. WPH is commonly found in medical protein supplements and infant formulas due to its greater ability of digestibility.

The Good Stuff

To begin, there are several ways in which whey protein powder can benefit your body. Here is a list of the main benefits and a couple of bonuses…

1. Muscle Mass / Strength

The main boost, the obvious one, is on muscle growth. Combining a solid whey protein powder along with a just as solid work out plan, focusing on resistance training, is a recipe for building muscle. Most popular among athletes, bodybuilders, and even fitness models, whey protein contains properties that promote muscle building, these include…

a. Leucine

An amino acid that stimulates muscle protein synthesis.

b. Creates/Aids Building Blocks

Since proteins are the building blocks of the body, and whey protein powder is packed with protein, they go hand in hand to create muscle.

c. Quick Absorption

Unlike other proteins, like casein, whey is absorbed for protein synthesis much faster. That is why in order to maximize your workouts, you should consume whey protein powder right after your workout. However, if your goal with whey protein powder is not only to put on some size but also to shed some fat, we got you covered too…

2. Weight Loss

Not known by many, whey protein powder can spark weight loss in your body. There are two ways whey enables weight loss, boosting metabolism, and satiate hunger. The protein you consume can enhance energy expenditure by up to 100 calories per day, along with daily exercise, calories will burn like wildfire.

Also, whey protein powder can cut cravings up to 60%.

However, when people want to lose “weight”, they most certainly mean lose “fat”. Whey protein not only melts fat but helps you keep and build lean muscle mass instead of losing it.

3. Other Benefits

Muscle building and weight loss are the main benefits of consuming whey protein. However, there are lesser-known effects that the protein could have on your body due to the high amount of cystine, an amino acid that is important for protein synthesis, detoxification, and diverse metabolic functions. The health effects include…

  • Reducing symptoms of stress/depression
  • Lowering Blood Pressure
  • Reduces symptoms of hepatitis
  • Protects against cancer
  • Improve the immune response in children with asthma
  • Improves immune function in HIV patients

Kidney Damage

It is proven that foods high in protein can and may accelerate damage to people who have kidney disease. I repeat; WITH A KIDNEY DISEASE. It is advisable to stay from whey if there is an issue with your kidney, however, for the healthy liver, it should have no effect all.


There is a connection with breakouts on the skin when consistently consuming high dosages of whey protein. Studies have shown that when on a high protein diet, acne increased when adding whey, but soon cleared up after cutting the protein. While the reason for this may be unknown, it is suggested that since whey is technically a dairy product, it comes from milk, it has a correlation with acne. So if you wonder where your new developed acne may be coming from try cutting whey and see if it may be the culprit.


Since some people are allergic to milk, they may be also allergic to whey. If unsure of having allergies to whey, symptoms include…

  • Bloating
  • Pain
  • Gas
  • Diarrhea

This is only a concise list of the total amount of allergies a person can experience when dealing with an allergen like whey. I didn’t cover some of the code-red allergic reactions that require using an epinephrine pen, or an Epipen. These kinds of allergic reactions are called anaphylaxis reactions, and could potentially lead to the death of a person. If you’d like to know more about that, click here.
