The Science Behind Cold-Pressed Whey Protein | ATACLETE

Cold-pressed whey protein is a type of whey protein that is processed using a method that involves low heat and high pressure, as opposed to the traditional method of producing whey protein which uses high heat and chemicals. This processing method results in a higher-quality product that is more easily absorbed and utilized by the body.

Here's an overview of the steps involved in making cold-pressed whey protein:

  1. Milk Separation: Milk is separated into curds and whey using a natural process such as fermentation, or through the use of rennet or other coagulating agents.
  2. Concentration and Purification: The whey is then processed to remove the remaining lactose, fat, and other impurities. This results in a concentrated form of whey protein.
  3. Cold-Press Extraction: The concentrated whey protein is then subjected to a process known as cold-press extraction, which involves the application of high pressure and low heat to extract the protein. This process is designed to minimize denaturation and preserve the quality of the protein.
  4. Filtering: The cold-pressed whey protein is then filtered to remove any remaining impurities, and to further concentrate the protein.
  5. Drying: The filtered whey protein is then dried to a powder form, which can be packaged and sold as a nutritional supplement.

The result of cold-pressing whey protein is a product that is nutritionally similar to traditional whey protein but with a few key differences. 

  1. Higher Protein Content: Cold-pressed whey protein is typically more concentrated than traditional whey protein, resulting in a higher protein content per serving.

  2. Lower Lactose and Fat Content: Cold-pressed whey protein is often lower in lactose and fat compared to traditional whey protein, making it a more suitable option for those who are lactose intolerant or have dietary restrictions.

  3. Higher Bioavailability: Cold-pressing whey protein results in a product that is more easily absorbed and utilized by the body, due to the minimization of denaturation that occurs during the processing.

  4. Enhanced Amino Acid Profile: Cold-pressed whey protein is a rich source of amino acids, including branched-chain amino acids (BCAAs), which are important for muscle recovery and endurance. Cold-pressing may also help to preserve the amino acid profile of the protein compared to traditional processing methods.



Athletes often choose cold-pressed whey protein because it is a high-quality source of protein, which is essential for muscle repair and growth. It is also rich in amino acids, including branched-chain amino acids (BCAAs), which are important for muscle recovery and endurance. Additionally, cold-pressed whey protein is often easier on the digestive system compared to other forms of protein, which is important for athletes who may have digestive sensitivities.

In a nutshell:

Cold-pressed whey protein may offer several benefits for athletes, including:

  1. High-quality protein: Cold-pressed whey protein is a high-quality protein source, meaning it contains all of the essential amino acids that the body needs to build and repair muscle tissue.

  2. Nutrient retention: Cold-pressed whey protein is minimally processed, which means that more of the natural nutrient content is retained, including amino acids, immune-enhancing compounds, and antioxidants.

  3. Digestibility: Some athletes may find that cold-pressed whey protein is more easily digestible and less likely to cause digestive discomfort compared to other forms of protein.

  4. Muscle recovery and growth: The amino acids in cold-pressed whey protein can help support muscle recovery and growth after exercise, which is important for athletes who engage in regular physical activity.

It's worth noting that the specific benefits of cold-pressed whey protein may vary depending on the individual athlete and their specific needs and goals.


In conclusion, cold-pressed whey protein is a superior choice for athletes over regular whey due to its high-quality protein content, amino acid profile, and easier digestibility compared to other forms of protein.


It is also important to note that not all cold-pressed whey protein products are created equal, and it is essential to choose a high-quality product that is third-party tested for purity and potency- Ataclete is no exception to the rule. Additionally, some cold-pressed whey protein products may contain added sugars, artificial sweeteners, or other ingredients, so it is important to carefully read the label and choose a product that aligns with your specific dietary needs and goals.
