Whey Protein Review

Whey Protein Powder:

Whey protein is derived from milk and is quickly absorbed by the body, making it an excellent choice for post-workout recovery. It’s considered a complete protein, meaning it contains all nine essential amino acids that your body needs to build and repair muscle tissue. The two types of whey protein are concentrate and isolate.

The main difference between whey protein concentrate (WPC) and whey protein isolate (WPI) is the level of protein purity. WPC contains about 70-80% protein, while WPI is more concentrated and typically contains at least 90% protein.

Whey protein concentrate is produced by filtering whey through a membrane to remove most of the fat and lactose, leaving behind a concentrated protein powder. It may still contain small amounts of fat, lactose, and other milk components, but this can vary depending on the specific product and production process.

Whey protein isolate, on the other hand, undergoes further processing to remove almost all of the fat, lactose, and other milk components, resulting in a powder that is much more concentrated in protein. This makes it a good option for people who are lactose intolerant or sensitive to dairy, as it contains very little lactose.


  • High-Quality Protein: Whey protein is a complete protein, meaning it contains all nine essential amino acids needed for muscle growth, repair, and recovery after exercise. It's also highly digestible and quickly absorbed by the body.
  • Muscle Building: Consuming whey protein can help to stimulate muscle protein synthesis, which can lead to increased muscle growth and strength over time.
  • Weight Management: Whey protein is a low-calorie, low-fat, and low-carbohydrate source of protein that can help to promote feelings of fullness and satiety, which may help with weight management.
  • Supports Immune Function: Whey protein contains immunoglobulins and lactoferrin, which may help to support immune function and promote overall health.
  • Versatile: Whey protein powder can be easily added to smoothies, oatmeal, or baked goods to increase their protein content and enhance their nutritional value.


  • Digestive Issues: Some people may experience digestive issues, such as bloating, gas, and stomach cramps, when consuming whey protein. This is more likely to occur in people who are lactose intolerant or have a sensitivity to dairy.



When choosing a high-quality whey protein powder, here are some factors to consider:

  • Source of Protein: Whey protein can come from different sources, including grass-fed cows, conventional cows, and even plants. Grass-fed whey protein is often considered to be a higher quality option because it comes from cows that have been raised on a natural diet and have not been exposed to hormones or antibiotics.
  • Processing Method: The method used to extract and process whey protein can also affect its quality. Cold-pressed, microfiltered, or ion-exchange methods are generally considered to be better options because they help to preserve the protein's natural nutrients and amino acids. Whey protein concentrates typically undergo less processing than isolates, which can result in a product that is closer to its natural form.
  • Purity: Look for a whey protein powder that has minimal additives, fillers, or artificial ingredients.
  • Testing: Look for products that have been tested by third parties. The site we like to use is labdoor. They perform tests and post results on all types of supplements. It's a great way to shop for safe and effective supplements.  

Overall, grass-fed whey protein powder can be a great choice for those looking for a higher quality option, as it is often considered to be more natural and sustainable than whey from conventional cows. It's important to note that the specific protein supplement you choose should be based on your individual goals, dietary needs, and preferences. It's always a good idea to consult with a healthcare professional or registered dietitian to determine which type of whey protein is right for you.
