Whey protein powder is the most popular option for the intake of supplemental protein that is readily available at the vitamin supply and health food stores. You might have certainly heard of it if you are into fitness. If not, you are in for a treat with the following article.
Milk consists of two types of proteins which are casein and whey. Once you have processed the milk, the remaining liquid is obtained to make yogurt or cheese. When whey is separated from the milk, you can further process it to produce different protein supplements like whey protein isolate and whey protein concentrate.
Standart Whey Protein:
Whey protein is obtained purely from milk. Milk consists of 80% of whey and 20% of casein protein. You first have to heat the milk to separate these two in the milk. Add the required enzymes that will coagulate the protein inside the liquid.
This process is primarily followed by dairy producers. When you dry the protein, producing a powder in the correct ratio, it will be the base of an ideal protein shake. Both the casein and whey proteins contain all the nine essential amino acids for creating all the muscles that most body-building athletes dream of.
Whey Protein Isolate:
Whey protein isolate consists of almost 90% of the protein, which is much higher than whey protein. To create whey protein isolate, you have to follow a process called “Cross-Flow Microfiltration.” This procedure separates the required protein from the cholesterol, lactose, and fat, giving a super-pure supplement in the end. It also indicates that whey protein isolates consist of low cholesterol, lactose, fat, calories, and carbohydrates compared to the other protein shakes present on the market.
But remember, whey protein isolate is not free of lactose and contains a little lactose content. That is why most sports enthusiasts prefer supplements with whey protein isolate who primarily suffer from dairy products. The body can easily digest and absorb the whey protein isolate. In every one scoop (25 grams) of whey protein isolate serving, you will get 21.9 grams of protein, 0.2 grams of carbohydrates, 91 calories, and 0.2-grams of fat.
Whey protein isolate supplements are perfect for everyone who wants to reduce fat and keep an eye on the fat, carbohydrates, and calorie consumption to ensure that you will get all the significant protein numbers. The low carbohydrate formula helps the body to quickly and easily absorb the protein and send it to the segments where it requires the most. The high protein content will assist our muscles in growing and repairing.
The amount of Protein Percentages
The primary difference between the whey protein and whey protein isolate lies in the protein quantity in every scoop of protein powder. Whey protein isolates are highly filtered and processed to consist of appropriately 90% of the protein in every scoop, with most of the lactose and fat terminated. In contrast to this, whey proteins contain nearly 25 to 89% of protein with carbohydrates and fats and consist of the remaining macronutrients.
Differences in the Carbohydrates, Fat, Lactose, and Budget
In addition to the lower carbohydrate content, whey isolate also consists of a low amount of lactose content. It makes it the best alternative for those who are intolerant and allergic to lactose. Whey protein isolates are much more expensive than whey protein due to the high protein concentration. Whey protein can concentrate and blend well and consists of a mixture of casein, whey, and other proteins. It also makes it one of the best affordable supplements for building muscles.
If budget is not one of the most significant factors to you and not restricting your carbohydrate, lactose, and fat intake, whey protein isolate is one of the best alternatives for your body.
Advantages of consumption of Whey Protein
Whey protein consists of nine essential amino acids, assisting you in promoting the lean muscle mass growth of the body. Whey protein is that part of the milk that is easier to digest and compared to the case in one. It is also easily digested by the gut and is distributed for use by the muscles. When you use this whey protein in combination with the exercise program, it might help you with the burning fat process and reduce weight as well. It reduces the cholesterol and blood pressure of the body.
Whey protein is also rich in branched-chain leucine amino acid, which is the fastest growth-promoting and anabolic protein. It is one of the most famous supplemental proteins implemented for muscle growth and muscle loss prevention that accelerates with age.
The primary difference between Whey Protein and whey isolate
The main difference between these two protein forms lies in the fat, lactose, and protein amounts present. Whey protein in its powder form contains anywhere between 11 to 14.5 % protein, 1 to 1.5% milkfat, and 62 to 75% of lactose. On the contrary, whey protein contains almost 90% of protein and 0.5% of milk fat and lactose. You can implement every whey protein product, supplemental or natural, causing no harm to your body.
Regardless of whatever protein form you will use, make sure that you will not exceed the daily intake of protein higher than 1.7 grams in every kg of daily body weight. Thus you should only consider taking supplements containing whey protein or whey isolate if there is a lack of protein in the diet.

Wrapping it up
Whatever supplement you are selecting, be it containing whey isolate or whey protein, look for products that will contain minimal sweeteners and additives. Some companies even add artificial flavors that include no nutritional value and might work against fitness and health goals. Among these two options, after considering all the benefits and drawbacks, we would recommend using whey protein in your diet as it is less processed and cheap than whey protein isolate.
