Common questions about whey protein and it’s benefits
How is whey protein made?
Whey protein is a co-product of the cheese making process. Listed below is a brief description of the steps involved in making pure whey protein isolate.
- Fresh milk is tested, approved by Quality Assurance experts and pasteurized.
- The casein (curd) and a portion of the milk-fat are separated out to make cheese.
- The remaining liquid whey goes through a series of fine, specialty filters to separate the whey protein from the lactose and other ingredients in the liquid whey.
- (For Whey Protein Isolate) The concentrated liquid whey goes through a Cross Flow Micro-filtration (CFM) and then an Ultrafiltration process. The CFM uses membranes that are about one micrometer to filter the product and the Ultrafiltration process uses membrane about .25 micrometer (or 250 nanometers). We have chosen this method an opposed to ion exchange as to not denature the isolate and leave the amino acids (glycomacropeptides, immunoglobulins, lactoferrin, some alpha lactalbumin) intact. This process removes majority of the undesirable components such as fat and lactose while leaving majority of protein micro-fractions and immune boosting components available.
- Next, the product enters a drying tower to remove water.
- The final step is to package the pure whey protein isolate and whey protein concentrate powders into various size containers for use.
Is there a difference between whey protein concentrate and isolate?
Yes, there may be a large difference between the two. Whey protein isolate is the most pure and concentrated form of whey protein powder available. It contains 90% or more protein and very little (if any) fat and lactose. Whey protein concentrate has anywhere between 29% and 89% protein depending upon the product. As the protein level in whey protein concentrate decreases the amounts of fat and/or lactose usually increase.

Why do I need protein?
Protein is an important nutrient needed by everyone. It is made up of essential and non-essential amino acids, which are the “building blocks” for healthy bodies. Protein has a number of different roles in the body including the following:
- Repair body cells
- Build and repair muscles and bones
- Provide a source of energy
- Control many of the important processes in the body related to metabolism
BFDNutriton whey protein concentrate and isolate are complete proteins meaning they have the full spectrum of essential amino acids to maintain, build and repair muscle mass.
How are essential and non-essential amino acids different?
How much protein does a person need each day?
Protein needs vary by person depending upon age, weight, sex, activity level and overall health. Athletes and individuals with special medical needs often need more protein than the recommended dietary allowance, or RDA.
Is whey protein good for athletes and people who exercise?
Is whey protein compatible with a low-carbohydrate diet?
Yes. Whey protein is not only compatible with low-carbohydrate diets it is an ideal choice.
Will whey protein help me lose weight?
Adding whey protein to the diet is a great way to jump-start a weight loss program. Whey protein is a key ingredient in numerous weight loss and meal replacement products and whey protein isolate (with no fat or carbohydrates) is often the preferred choice. Studies have found that individuals who combine diets with leucine rich protein foods, like whey protein, and exercise have more lean muscle tissue and they lose more body fat. As they lose fat, their metabolic rate increases and they naturally burn more calories each day. Another way that whey protein helps manage weight is by promoting satiety, or a feeling of fullness. One recent study showed that whey protein was superior to casein, the other protein in cow’s milk, in promoting satiety.
Is whey protein a good protein choice following bariatric weight loss surgery?
Following bariatric surgery it is important to follow a special diet designed by a physician and/or nutrition professional. Protein plays an essential role in that diet as it is the primary food source following surgery. Inadequate amounts may contribute to hair loss, muscle loss, and poor skin tone.
Whey protein isolate is an excellent protein choice post-surgery as it is very easy to digest and efficiently absorbed into the body. It doesn’t sit in the stomach for long periods of time like beef and other protein foods that may upset your system.
How does whey protein compare to other types of proteins?
Protein foods are not equal and can vary in a number of ways including the following:
- Number and quantity of essential amino acids
- Digestion and absorption rates
- Fat content
Whey protein is a very high quality complete protein with rich amounts of all the essential amino acids. Whey protein isolate is the purest form of whey protein, which is why it is absorbed so quickly and efficiently into the body.
How does whey protein compare to soy protein?
Here are some of the differences between whey protein and soy protein.
- Whey protein is a nutritionally complete protein. It contains bioactive ingredients, like immunoglobulins and lactoferrin, which help support the immune system.
- Athletes prefer whey protein to soy protein due to its rich abundance of branched chain amino acids and its quick absorption rate. These are important to help repair and rebuild muscles after a workout or competitive event.
- Whey protein has a fresh, neutral taste compared and will not change the taste of foods you add it to.
- Whey protein does not contain isoflavones or any other components with potential hormonal effects.
I eat a lot of fish, chicken, eggs, soy and beef. Why do I still need whey protein?
Can I get enough whey protein by drinking milk?
Milk is a highly nutritious beverage however, it only contains about 1% of whey protein. In order to get all the benefits of whey protein, you need to take a concentrated whey protein powder.
Are all whey proteins the same?
No. There may be a major difference in the quality of whey protein based upon the following factors:
- Source of Milk
- Production Method
- Type of Cheese Produced
- Individual Manufacturer Specifications
- Added Ingredients
What individual components are found in whey protein?
Whey protein is a combination of a number of individual protein components:
Beta-Lactoglobulin, Beta-Lactoglobulin, Glycomacropeptide, Glycomacropeptide (GMP), Alpha-lactalbumin, Alpha-lactalbumin, Lactoferrin, Lactoferrin, Immunoglobulins, Immunoglobulins, Lactoperoxidase, Lactoperoxidase, Bovine Serum Albumin, Bovine Serum Albumin (BSA), Lysozyme, Lysozyme
Is whey protein easy to digest?
What is hydrolyzed whey protein?
When whey protein is hydrolyzed the protein chains are broken down into smaller segments called “peptides”. Hydrolyzed whey protein is still a high quality protein however, it is less likely to cause an allergic reaction than non-hydrolyzed whey protein. It is most commonly used in infant formulas and specialty protein supplements for medical use.
If I'm lactose intolerant should I avoid whey protein?
Is whey protein a good choice for vegetarians?
Yes, whey protein is an excellent choice for vegetarians who include dairy products in their diet.
Does whey protein contain gluten or wheat protein?
Is whey protein safe for pregnant women and children?
Whey protein is a complete high quality protein and should be an acceptable protein source for healthy pregnant women and children, provided they are not allergic to dairy proteins. The second most abundant component in whey protein is alpha-lactalbumin, which is one of the main proteins in human breast milk. Infant formulas often contain whey protein, including special formulas for premature infants. Prior to taking whey protein, both pregnant women and parents of young children should consult a physician to be sure whey protein is right for them.
What are the side effects of taking whey protein?
Products are great and the prices are great. I love BFD Nutrition!Brady S.
