As you know, protein is an indispensable element for building muscle; but what is whey protein? Have you ever heard of it before? Whey protein is extracted from milk. Administered in powder form, it possesses countless properties.
Whey protein is considered a complete protein because it contains the nine essential amino acids that the human body cannot produce on its own. Protein is necessary for muscle growth and is vital for athletes; it also possesses other nutritional advantages that you should be aware of, as you will see below.

Shopping Guide: Everything you should know about whey protein
Before purchasing whey protein supplements, it is advisable to ask yourself a series of questions, such as for example for whom these food supplements are intended or why they are recommended in certain situations. In this section we address the most frequently asked questions from consumers.
What is whey protein exactly?
Whey protein contains tryptophan: what does it mean?
Why is whey protein so healthy?
Its benefits are related to a powerful antioxidant called glutathione. People with HIV, liver disease, diabetes, and various cancers can develop low levels of glutathione in the body. The body can make its own glutathione from the amino acid cysteine, and whey has a high cysteine content.
Why is whey protein so important for athletes?
Whey protein will make muscle recovery after exercise faster and more effective.
Additionally, it is extremely important to consume a high level of daily protein in order to increase or preserve muscle mass. For athletes, muscle mass is essential for an energetic workout and for burning calories in passive state.
What is the biological value of whey protein?
The higher the biological value of your protein source, the less you will need in order to build muscle mass.
In the following table, you can find the biological value of whey protein compared to other protein foods:
|Protein source||Biological value|
Does whey protein influence asthma symptoms?
Are whey protein supplements beneficial?
Did you know that numerous studies show that whey supplements and protein in general can help you lose fat and keep you feeling full longer than any other macronutrient?
This supplement is much more than just protein: whey contains many nutrients that provide us with amazing biological effects. It is not without reason that this supplement is one of the most researched in the world.
When should I take whey protein?
Let’s see in the table below when you should take whey protein:
|After training||Before training||Before sleeping|
|As already mentioned, it is positive because it also promotes muscle repair. After consuming the protein, it is better to eat at least every 2 hours for the next 6 hours.||Taking it immediately before a workout will have no effect. In other words, take your protein shake at least one hour before training, rather than waiting until the last moment.||When you sleep, your muscles are still recovering, so it is a good idea to maintain protein levels for as long as your body goes into mild starvation mode.|
Is an excess of whey protein recommended?
The safety of whey protein supplements depends largely on the dose. Excess protein will be stored as fat in the body and may increase the risk of dehydration. Additionally, there are a number of adverse effects if you consume too much whey protein, as we have listed below:
- Kidney problems. Excessive intake of whey protein can cause kidney problems, especially if you already suffer from this. Experts recommend controlling your whey protein intake and consulting your doctor before you start taking it.
- Liver problems. Too much whey protein can worsen liver problems. This is why it is important to consume protein in moderation. It is also advisable to consult your doctor before taking whey protein, as it can interfere with the effects of the medications you take for your liver condition.
- Increased blood acidity. Another side effect of whey protein intake is a rise in blood pH. When there is too much protein in the blood, the kidney has trouble metabolising it. This results in increased blood acidity.
Is whey protein advisable for people with milk allergies?
Is whey protein suitable for vegans and lactose intolerant individuals?
Does whey protein interact with other medications?
Next, you will see which are the cases in which you should not use whey protein if you must take medication:
- It may decrease the effectiveness of levodopa, the medication for Parkinson’s disease. Do not take whey protein and levodopa at the same time.
- It may reduce the amount of alendronate absorbed by the body. Alendronate is a medication for osteoporosis. Do not take whey protein until two hours after taking the medicine.
- It may reduce the absorption of some antibiotics. It is recommended that you take the antibiotics one hour after taking the whey protein.
What are the symptoms of a whey protein overdose?
What is the appropriate dose of whey protein?
- To determine the necessary or correct dosage of whey protein per day and meal, the overall amount of protein should also be taken into account. Considering between 0.8 and 2 grams of protein per body weight are ideal, the amount of powder should be adjusted.
- On average and depending on sex and weight, the total amount of protein per day is about 100 grams, making it difficult to meet the necessary protein requirements with a standard diet without adding the powder. Since the body simultaneously excretes proteins that are not needed, overdose with the powder is avoided.
What types of whey protein exist, and which is the right one for me?
There are essentially three types of whey protein: whey protein concentrate, whey protein isolate, and whey protein hydrolysate. The whey protein concentration and its benefits are different in each, as we will see below.

Whey protein concentrate
It contains low levels of fat and low levels of carbohydrates. It is the most natural whey protein, and therefore the cheapest. It contains between 70 and 80% protein, the rest being fat and carbohydrates. It is also the tastiest. It improves the immune system and its effect is antioxidant.
Whey protein isolate
It contains more than 90% protein and is processed to eliminate most of the lactose, carbohydrates/sugars, cholesterol, calories and fat. It is very useful for those who want to lose weight and for people intolerant to lactose.
Whey protein hydrolysate
It allows for a faster absorption. It also increases insulin significantly more than concentrate or isolate, but reduces the potential for allergic reactions. It is the most expensive of the three and generally has the worst taste. It is principally designed for after training.
Next, we will explore the different whey protein products to find out what criteria you should take into account when purchasing a supplement. With these specific characteristics, you can easily decide which product is best for you and make a good purchase decision.
You should primarily consider the following:
A good formula is to calculate the price of a gram of powder and compare it to the daily dose recommended by the manufacturer.
BCAA (branched-chain amino acids)
BCAAs, or branched-chain amino acids, are three essential amino acids with one very interesting characteristic: they can be used directly by muscle tissue. As a result, muscle growth is generated and muscle regeneration is accelerated.
Please note that whey protein contains at least 7 of the 8 essential amino acids that our body needs and cannot create on its own.
Here are the levels at which amino acids should be found:
- Isoleucine: 6.2 g – 9.5 g
- Leucine: 4.3 g – 9.9 g
- Lysine: 4.3 g – 9.9 g
- Valine: 6.1 g – 9.3 g
- Phenylalanine: 1.0 g – 3.6 g
- Threonine: 3.3 g – 6.9 g
- Methionine: 0.8 g – 2.4 g
- Tryptophan: 0.4 g – 2.1 g
Typical allergens are mainly eggs, milk, soybeans, gluten, fish, crustaceans and various types of nuts (such as peanuts, cashew nuts, almonds, hazelnuts, etc.). If you are allergic, a good option is Xcore Xtreme 100% Whey Protein.
Pure hydrolysate reaches 95% protein. When buying a powdered mixture, remember that the amount of amino acids can be lower, so you should make sure that at least 75% be protein.
If this is not the case, you may conclude that the hydrolysate is not pure or that its amount is low. The price is sometimes high because we pay for the brand and not the macronutrients.
Taste is important, but it is not a buying criterion for trying a new brand because you must buy it to try it. Taste comes into play when you decide to buy the same brand over and over again.
As you have seen throughout the article, there are several types of whey protein and you must purchase the most suitable for your physical conditions. Whey protein has many benefits, especially for athletes, but you must moderate your intake.
On the other hand, you must not allow elegant labels to persuade you. Read the package instructions carefully before deciding to purchase a whey protein supplement. Marketing sells, but doesn’t create a great product.
