What Is Protein Isolate?
If you’re new to the fitness lifestyle, you may not know what protein isolate is, and if so, we’re here to tell you! Protein isolate is a concentrated protein form that’s separated from other food sources. It’s commonly used by athletes and bodybuilders to improve muscle mass and as a dietary supplement.
Whey protein, which is derived from cow's milk, contains all of the essential amino acids that help with the growth and repair of lean muscle tissue, particularly the branched-chain amino acids (BCAAs) — leucine, isoleucine, and valine.
Compared to other protein forms, whey protein isolate undergoes a more rigorous purification process. This process removes any additional fat, carbohydrates, cholesterol, and lactose. It really is protein in its purest form!
In a nutshell, whey protein isolate is a simple form of protein that doesn’t contain any extra macronutrients. This makes it ideal for those who want to improve their body composition and burn fat since it contains fewer calories, less fat, carbohydrates, and sugar compared to other protein supplements.
How Protein Isolate Works
Protein isolate works by giving your body the important amino acids it needs for building muscles. When you work out, your muscles break down and require repair, a process called protein synthesis, which — as you may or may not know — relies on amino acids.
These essential amino acids, the basic building blocks of protein, are found in foods like meat, poultry, fish, eggs, and dairy. However, the body can only use a limited amount of protein from these sources. That's where protein supplements come in handy.
By taking protein isolate after your workouts, you’ll no longer have to worry about whether you’re getting enough protein to help rebuild your muscle cells. Protein isolate is an excellent way for athletes to get all the protein they need — without also acquiring unnecessary fat and carbohydrates.
The Benefits of Protein Isolate
To reach your fitness goals, it's not enough to just exercise regularly or go for daily runs. Proper recovery requires giving your body muscle-building nutrients after you exercise. Whey protein isolate is a product that supports this process quite well.
While there are plenty of different types of protein supplements available, including grass-fed whey protein concentrate and slower-digesting casein, the best protein isolate favors whey protein — both by professional athletes and those who are new to working out.
Whey protein isolate might just be exactly what you need to help you reach your health and fitness goals. Why, you might ask? Great question! Let’s talk about the many benefits of protein isolate below.
Whey Protein Isolate is Easy to Digest
The last thing you want to deal with after a high-intensity workout is stomach pain. We’ve all been there. Nobody wants to be doubled-up and holding their stomach after working out. Thankfully, whey protein isolate is easy for your body to digest because it absorbs quickly, and processes faster than other types of protein.
To further improve absorption, you should mix your favorite whey protein isolate with a liquid of your choice. It should help to regulate bowel movements (we apologize if that’s TMI, but it’s good to know!) and can be especially suitable for those who suffer from lactose intolerance. Research from Cambridge suggests that due to its quality and absorption, whey protein isolates may improve insulin levels and fasting lipids, too.
Low in Fat and Carbs
Finding something low in fat and carbs is pretty great, especially when you're watching your diet. Among many products with extra carbs and fat, whey protein isolate stands out for being low in both. Choosing to take whey protein powder after you work out allows your body to get the protein it needs without the extra calories from additional ingredients.
Plenty of Amino Acids
Whey protein isolate, in its pure protein form, contains all nine essential amino acids. Amino acids are super important for proper muscle repair and protein synthesis. Studies show that while BCAAs help with recovery and muscle growth, using all nine essential amino acids (EAAs) can increase muscle protein synthesis by up to 50%, compared to using only BCAAs.
Certain amino acids in whey protein isolate, like glutamine and leucine, also play a role in stimulating protein synthesis right after a workout. They also help reduce tissue damage and improve muscular endurance. Not only that, but cysteine assists in producing glutathione — a potent antioxidant that helps to preserve and maintain lean muscle mass.
Prevents Muscle Wasting
Not many people know this, but whey protein isolate is actually super helpful for people who are living with muscle-wasting diseases. It’s also a great choice for seniors and anyone who happens to be going through natural age-related muscle loss.
What’s more, if you're intentionally cutting calories to lose body fat, whey protein isolate will be your best friend. It helps keep your lean muscle intact while you’re dieting and ensures that you burn calories effectively all day long.
Frequently Asked Questions
What's the Difference Between Whey Protein Isolate and Whey Protein Concentrate?
Whey protein isolate is a natural dairy protein powder that's at least 90% protein. In contrast, whey protein concentrate has around 80% protein. Whey protein isolate has minimal sugar, lactose, or fat, which makes it a healthier option. However, whey protein concentrate is more cost-effective per gram of protein.
Is Protein Powder Pasteurized?
Whey protein powder comes from pasteurized whole milk, but the whey undergoes processing at low temperatures in a sterile environment in order to prevent protein denaturation. High heat during pasteurization can denature whey proteins, which can sometimes lead to hydrophobic interactions and protein gel formation.
What's the Expiration Date of Whey Protein?
Every whey protein product has a labeled best-by date. Consuming protein beyond this date might give you an upset stomach due to the breakdown of colorings and flavors. While the risk of bacterial growth is low, fat-containing whey protein can go rancid due to oxygen exposure. We’d definitely recommend strictly following the best-by date for safety.
Can People Who Are Lactose Intolerant Eat Whey Protein?
Whey protein isolate contains trace amounts (about 0.5g per serving) of lactose. Most lactose-intolerant people can safely consume whey protein without any negative side effects, but you may want to ask your doctor if your lactose intolerance is particularly severe.
