Why Whey Protein?
May 2024When you follow a healthy lifestyle, counting calories and watching your sugar and salt intake have probably become second nature. But a lot of people do not realise the importance of ensuring that your body gets the protein it needs to flourish. Protein is essential to grow and repair various cells. An easy way to ensure that your body receives the required supplement to thrive is to add whey protein to your diet.
What is whey protein?
Milk consists of two proteins, namely casein and whey. When they process milk into yogurt or cheese, they call the remaining liquid whey. Therefore, if you ever see a watery liquid on top of yoghurt, do not throw it away, as it is a nutritious source of whey protein.
Whey protein and amino acids
Whey protein is a complete that contains all the essential amino acids. But what are amino acids, and why is it important?
Amino acids are molecules that combine to create proteins. Researchers classify these molecules, which contain 20 organic compounds, into non-essential and essential amino acids.
Your body produces non-essential amino acids, so you don't have to add them to your diet. Conversely, your body cannot produce essential amino acids (EAAs), so you must add them to your diet.
From a fitness point of view, amino acids can help to repair damaged muscle and build new muscle, while from a health and wellness perspective, amino acids can help to regulate the immune system, assist with calcium absorption, encourage skin elasticity, and assist with the synthesis of neurotransmitters and hormones.
Why add whey protein to your diet?
Contrary to what many people believe, it isn’t just for athletes and fitness enthusiasts. Many rely on supplementation to help meet their daily protein needs, lose or gain weight, or recover from an injury or surgery. You can therefore add whey protein to your diet, even if you do not exercise daily.
Below, you'll find the benefits of adding protein to your diet:
- It can help with weight loss
Increasing protein intake can positively affect weight loss, as it reduces your level of the hunger hormone known as ghrelin. Protein also helps you feel fuller for longer, reducing cravings and preventing you from snacking. Whey protein is very digestible and gets absorbed from your gut quicker than other protein sources.
- It can promote muscle growth
Protein is the building block of muscles; eating adequate amounts of protein helps you maintain your muscle mass and promotes muscle growth during strength training. Whey protein is rich in the branch-chain amino acids known as leucine, the most growth-promoting (anabolic) of the amino acids. Leucine also helps to prevent muscle breakdown and encourages muscle recovery.
- It can promote healthy skin, nails & hair
Since protein is one of the key building blocks of skin tissue and supplies the body with the essential amino acids required to make keratin, it is evident that it will help with healthy skin, nails and hair.

The different types of whey protein
There are three types of whey protein, concentrate, isolate and hydrolysate. These types of whey protein have different protein, lactose and fat contents.
- Whey protein concentrate
Is the least processed form of whey protein and therefore keeps the health-promoting nutrients that are naturally present in whey. This form comprises low levels of fat and carbohydrates. The percentage of protein in concentrate depends on how concentrated it is.
- Whey protein isolate
Isolate is further processed to remove most of the carbohydrates, lactose and fat, and usually contains at least 90 percent protein. Try our ISOPRO whey isolate formulation
- Whey protein hydrolysate
Hydrolysate is viewed as the ‘pre-digested’ form as it has already undergone partial hydrolysis (a process required for the body to absorb protein). Hydrolysate is the easiest for the body to digest, resulting in a sharp rise in blood insulin levels, which can encourage lean muscle growth.
Why not try our Blue Lab Whey formulation which contains a blend of all three types for a complete, easy digesting, high protein addition to your diet. Now available in three new flavours, Blueberry Chocolate Gateau, Chai Latte and Cookies and Cream flavour.
