Whey Protein Isolate vs. Whey Protein Concentrate

If you're worried that you might not be getting enough protein, you may be looking toward adding a protein supplement to your routine. Incorporating a protein powder like whey into your diet has several benefits. Your body requires protein for countless functions ranging from repairing and rebuilding muscle to satiety. When searching for a whey protein powder to purchase, you'll encounter two types: whey protein concentrate and whey protein isolate. Though each comes from whey, these protein powders have slightly different functions. Are you curious to learn which type of whey protein is best for your diet and lifestyle? Continue reading as we dive into the benefits of whey isolate protein vs. whey concentrate.

What Is Whey Protein?

Whey is a type of protein found in milk. Whole milk contains two proteins: whey and casein. Milk separates into curds (used to make cheese) and liquid whey during the cheese-making process. The whey is then pasteurized, dried and turned into a powder with several uses. Whey protein is by far the most popular protein powder around. Food manufacturers use whey to boost the protein content in protein bars, drinks and cereals. However, it's also intended for at-home use and can be added to smoothies, baked goods and even oatmeal.

Who Needs Protein Supplements?

While most individuals meet their daily protein requirements, those who live an active lifestyle and are looking to build muscle may benefit from a diet higher in protein. Adding whey to your diet is a great way to boost your protein intake and provide your body with essential nutrients. As a complete source of protein, whey contains all nine essential amino acids required by the body. Whey is also easily digested, which means that your body can use those amino acids as soon as you consume them. If you're new to the world of protein supplements and looking to incorporate more protein into your diet, we recommend starting with whey. Whey is easy to use and features a mild taste that won't change your recipe's flavor. making whey protein shake

What Is Whey Protein Isolate?

Whey protein isolate is a highly processed form of whey protein. Because whey comes from dairy, whey protein typically contains minimal lactose. When making whey protein isolate, the filtration process is so throughout that the lactose is essentially removed. Whey protein isolate is also whey protein in its most pure form. Therefore, it has less fat, cholesterol, carbohydrates and calories than whey protein concentrate. This being, whey protein isolate is the better choice for lactose intolerant individuals and those looking to maintain muscle while losing fat. When purchasing a whey protein isolate, seek out those that contain at least 90% protein. The higher the protein content, the more concentrated the whey isolate is.

What Is Whey Protein Concentrate?

Whey protein concentrate and whey protein isolate are the same types of protein. However, the protein content of whey protein concentrate depends on how concentrated it is. Whey protein concentrate typically contains less protein (between 70-80%) and a higher amount of lactose than isolate. That being so, it's also rich in BCAA's (branched-chain amino acids) and glutamine, nutrients that are essential to recovering from a challenging workout. Whey protein concentrate is an excellent choice for individuals looking to build or maintain muscle. It's not suitable for people who are lactose intolerant.

Whey Protein Isolate Benefits

Whey protein isolate offers several unique benefits. Here are a few of the most notable.

Low in Carbs and Fat

If you're following a low-carb diet, finding the right protein powder is crucial. Whey protein isolate is low in carbohydrates and fat, making it an excellent way to supply your body with the protein it needs without packing too many calories.

Easy to Digest

Whey protein isolate has a high absorption rate and is processed much faster than other forms of protein. Its ability to be easily digested means that your body can use it as needed. Whey protein isolate also helps regulate bowel movements and can be consumed by people who have a sensitive stomach. Additionally, its near-to-nothing lactose content means that even lactose-intolerant individuals can enjoy it. whey protein shake blending

Whey Concentrate Benefits

Satiety

Boost Immunity

Whey protein concentrate contains more milk-based nutrients when compared to whey protein isolateenzymes and antioxidants like glutathione work to protect your cells from stress and boost your immune system simultaneously. So consuming whey protein concentrate can keep you feeling your best, even when things get overwhelming.

Bioavailable

Some proteins are more accessible to digest than others. Proteins that are hard to digest don't have much nutritional benefit since our bodies cannot adequately use them. To measure how easily the body can digest a protein, scientists created a scale called the Protein Digestibility Corrected Amino Acid Score (PDCCAS). The scale runs from 0-to 1, with one being the most bioavailable. Whey protein is one of the few proteins to score a 1. Its easy-to-digest profile makes it excellent for individuals with sensitive stomachs or those struggling with nutrient absorption.

Is Whey Protein Gluten Free?

Pure whey protein powder is gluten free. However, that doesn't mean that every whey protein you find will be. When searching for a gluten free whey protein, pay close attention to the ingredients. Many protein manufacturers will add flavors, sweetener and additives that may contain gluten. Additionally, certain whey protein powders may be packaged in a gluten-containing facility and unsuitable for individuals with celiac disease. If you're searching for a gluten free whey protein powder and notice wheat, barley, rye, glutamine, malt sugars, or starches on the label, we'd recommend purchasing a different one.

Is Whey Protein Vegan?

Whey protein No form of whey protein powder is considered vegan because it comes from the animal product milk. While processing may remove some lactose, it does not change where the protein powder comes from, meaning whey protein is not suitable for a vegan diet. Luckily, there are several plant based protein powders that you can consume on a vegan diet. Pea protein, soy protein and hemp protein are just a few of the many vegan protein powders available.
