Whey Protein Isolate vs Whey Protein Concentrate

All of us are aware of the importance of proteins in the growth and development of the human body. Proteins help in promoting the bone and muscle strength and enhance our endurance and immunity. The synthesis of proteins is achieved with the help of organic compounds called amino acids. Amino acids are categorized into essential and non-essential amino acids. Since essential amino acids are not synthesized within the human body, the importance of following a diet rich in essential amino acids becomes very important. This is where whey protein comes into picture. If you go through the nutrition facts about whey protein, you will see that its amino acid profile is complete in itself. Both whey protein isolate and whey protein concentrate are forms of whey protein. If you are planning to include whey protein powder in your diet, going through the comparison between the two will tell you which one is healthier. Before we move on to the differences between these two forms of whey protein, let's understand what whey protein is and how this nutritious protein product is made.

How is Whey Protein Made

Whey protein is a rich source of protein that is derived from cow's milk. It is basically a by-product of cheese production. Cheese is produced by curdling milk, and the watery part that is separated during the production of cheese, is referred to as whey. This liquid is passed through fine filters so as to separate the globular proteins from other ingredients that form a part of this liquid. The concentrated whey is placed in an ion-exchange tower for purifying and concentrating whey protein. After that, this concentrated form is processed and dehydrated in a drying tower. This concentrated powdered form of whey protein is then packaged and is ready for use. While buying whey protein supplements for yourself, you would have seen whey protein is sold in various forms such as whey protein isolate and concentrate. Well, these are two forms of whey protein, that vary in terms of protein as well as fat content. Let us start with the composition of these two forms of whey protein. Whey protein isolate comprises 90% or more protein and is a purer and more concentrated form of whey protein. On the other hand, the protein content in whey protein concentrate lies between 29% and 89%. Unlike whey protein isolate, where the fat and lactose content is minimal, fat and lactose content is higher in whey protein concentrate.

How is Whey Protein Isolate Different from Whey Protein Concentrate

The health benefits of whey protein are numerous. Earlier whey protein powder was mainly used by athletes and body builders, but due to the increasing awareness of its health benefits, many fitness enthusiasts and health-conscious people are now using this supplement. It is easily digestible and contains most of the essential amino acids that are not synthesized within the body. Those suffering from protein deficiency can greatly benefit by having whey protein. It certainly provides one with the stamina for high energy-consuming physical activities or intense workouts. Whey protein also helps in boosting the immune system. Whey protein also facilitates the production of an antioxidant called glutathione. Thus, it may help in reversing free radical damage. One of the common whey protein isolate benefits is its ability to promote weight loss. Use of this protein powder helps in suppressing one's appetite, and the feeling of fullness suppresses hunger pangs. Thus, it can help you cut down your intake of food.

For people who are trying to lose weight, consumption of whey protein isolate is a better choice than whey protein isolate. This is due to the low fat content in whey protein isolate. Besides the presence of essential amino acids, the low content of cholesterol makes whey protein isolate a very healthy muscle building supplement. Since the amount of lactose in whey protein isolate is minimal, it is also a preferred choice for people who are lactose-intolerant. However, one must note that the process of filtration does lead to the removal of some of the immune-boosting ingredients such as lactoglobulins and lactoferrins. Since whey protein isolate has a higher protein content, it will cost you more than whey protein concentrate. So, if you are not too keen on shelling out more, and you feel that you can get protein from other dietary sources, whey protein concentrate would be a better choice. Though whey protein is a complete protein, excessive consumption for a prolonged period of time can cause damage to liver and kidneys. So, consult a nutritionist or a doctor regarding the right dosage.

On a concluding note, the comparison between the two forms of whey protein tells us that both forms have their own advantages and disadvantages. Which one is better for consumers, would depend on their overall health and priorities. If you are lactose-intolerant, whey protein isolate is a better choice for you, but for those who don't have problems having foods rich in lactose, whey protein concentrate would suffice. Various brands are offering protein supplements, so, make sure that you buy the best whey protein powder manufactured by a reputed brand. You can also look for protein powders that offer a combination of both these forms of whey protein. Since an overdose can cause certain side effects, make sure that you take it as per prescribed dosage.
