What is Whey Protein Isolate

Many athletes consume and recommend protein powder in order to meet the daily requirements of protein to increase their muscle growth and recovery. Whey Protein Isolate is a highly recommended supplement and very common in the sports and fitness industry. Nonetheless, with so many types of proteins on the market, how can one tell the differences between them? What is whey protein isolate? Whey powder and Whey isolate are today’s two most popular protein powders.

At NATURALTEIN, we create protein powders consisting of all-natural ingredients. Read on to know what makes us different in the market.

Difference Between Whey Protein And Whey Isolate; whey protein vs whey protein isolate

whey isolate vs whey protein

Both Whey Protein and Whey Isolate are derived from milk. However, Whey Isolate is just whey protein that is more fleshed out in order to reduce the amount of lactose in the powder. This will produce a leaner protein source that is lower in fat. Whey protein and whey isolate have different protein, lactose, and fat content per serving.

A serving of whey protein can contain anywhere from 10-15% protein with over 50% lactose and almost 2% fat.

What is whey protein isolate made of?

whey protein contents

What is whey protein made from? Whey protein isolate is made of whey, a by-product of cheese production. Whey is rich in protein and amino acids and is a pure form of whey filtered to remove fat and lactose. A serving of whey isolate contains over 90% pure protein content and virtually no lactose or milk fat. Whey isolate can benefit those who are lactose intolerant or have trouble digesting dairy products.

Isolate or Concentrate: isolate protein vs whey protein concentrate?

Whey Concentrate and Isolate are almost identical in building muscle and aligning your training goals. The reason people prefer to isolate over concentrate is lower fat and carb content. Fewer calories per serving if you have lactose intolerance; isolate is best. Avoid whey isolates and concentrates, which eliminate the benefits of no lactose and low fat and carbohydrate content.

When one is preparing for a bodybuilding show or competition where you need to track calories carefully, whey isolate is the best product choice for you. However, whey concentrate or whey isolate will provide benefits if you are not particular about how many calories you consume.

While the nutritional contents of both concentrate and isolate are very similar, isolate is a healthier choice for those who have bloating issues caused by dairy products. If you want to build a lean physique, either one of the two products will provide you with great muscle development, maintenance, and growth benefits.

Why is whey protein isolate so expensive?

Many ask us what is whey protein isolate or what makes it different. Usually, whey protein contains all five essential amino acids, as well as non-essential amino acids and BCAAs. Since your body cannot produce the essential amino acids, Whey is a great method of supplementing those. It also offers additional health benefits making it slightly more expensive than other proteins. As it gets absorbed faster, Whey helps a lot with bodybuilding. Quality supplements use quality ingredients, which is why isolated protein is a bit more expensive. The more Whey is processed, the more costly it gets. Isolates and hydrolysates go through more processing, which is why they are more expensive than concentrates.

What makes Whey Protein so special?

Despite its reputation as another protein source, Whey Protein is special because it has an incredible amount of BCAAs, making it a complete protein. Whey Protein is well-absorbed and contains all the essential amino acids compared to other protein sources.

It is also highly bio-available, meaning it is completely absorbed and has the highest biological value of all protein sources.

What is the basic difference between Whey Concentrate and Isolate?

Whey concentrate vs isolate protein is a big topic. Both are high-quality protein supplements that come from milk; the difference lies in the extra filtering that Whey Isolate goes through. Because of this extra step, Whey Isolate results to be a more refined and pure form of Whey Protein that has almost no sugar, lactose, or fat. Typical whey protein concentration contain 80% protein and can contain lactose, fat, carbohydrates, and minerals. Compared to Whey Protein Concentrate, Whey Protein Isolate is slightly more expensive. Of course, the additional processing it goes through removes virtually all of the non-protein components. It offers 90% protein content, with barely any fat or lactose. Whey Isolate tends to be lower in bioactive compounds than Whey Concentrate.

Following an intense workout, your muscles are prone to absorb more amino acids. So consuming a Whey Protein shake post-workout will support quick muscle recovery and increase muscle protein synthesis.

How much Whey Protein should one consume in a day?

We suggest 30g per day as a serving size. A healthy diet should contain 0.8g to 1g of protein per kilogram of body weight for the body to regenerate damaged muscles following an intense workout and initiate muscle protein synthesis. That doesn’t mean a person weighing 60kg should consume that much protein per day. Regular diets provide sufficient protein for most people. You’ll be getting a certain amount of protein from your diet if you eat legumes, nuts, eggs, poultry, and seafood. Whey protein supplements fill in the protein gaps left your varied diet can’t offer and aid in quick muscle recovery, even if consumed in moderation.

Should I consume a Whey Protein shake on rest days (non-workout days)?

The answer is yes. While you are resting, you can also consume Whey Protein Shake.
