What is Whey Protein ?

Whey protein is a high-quality protein derived from milk during the cheese-making process. It constitutes approximately 20% of the total protein content in milk. Whey is separated from the curd during the production of cheese and undergoes processing to remove water, fats, and lactose, leaving a concentrated protein powder. Known for its complete amino acid profile, whey protein is rich in essential amino acids, including branched-chain amino acids (BCAAs), which play a vital role in muscle protein synthesis. Its rapid absorption by the body makes it an effective and popular supplement for athletes, fitness enthusiasts, and individuals looking to support muscle growth, recovery, and overall health. Whey protein is available in various forms, such as concentrate, isolate, and hydrolysate, each with different protein concentrations and processing methods to meet diverse nutritional needs.

What are the Benefits of Whey Protein?

Whey protein is a high-quality protein derived from milk during the cheese-making process. It offers several benefits, making it a popular choice among athletes, fitness enthusiasts, and individuals looking to supplement their protein intake. Here are some of the key benefits of whey protein:

  1. Complete Protein Source: Whey protein is considered a complete protein because it contains all essential amino acids that the body cannot produce on its own. This makes it an excellent choice for supporting muscle growth and repair.

  2. Muscle Building and Repair: The high concentration of branched-chain amino acids (BCAAs) in whey protein, especially leucine, plays a crucial role in stimulating muscle protein synthesis. This can help promote muscle growth and aid in recovery after exercise.

  3. Weight Management: Whey protein can be beneficial for weight management due to its ability to promote satiety and reduce overall calorie intake. Including whey protein in your diet may help with weight loss or weight maintenance by supporting a feeling of fullness.

  4. Antioxidant Properties: Whey protein contains bioactive peptides with antioxidant properties, which can help protect the body’s cells from oxidative stress. Antioxidants are important for overall health and may contribute to reducing the risk of chronic diseases.

  5. Immune System Support: Immunoglobulins and lactoferrin present in whey protein have been shown to have immune-boosting properties. Regular consumption of whey protein may contribute to a stronger immune system.

  6. Fast Absorption and Digestibility: Whey protein is rapidly absorbed by the body, making it an ideal post-workout supplement to quickly deliver amino acids to muscles. Additionally, whey protein is generally well-tolerated and easily digestible.

  7. Lactose Content: While whey protein is derived from milk, the processing methods often remove most of the lactose. This makes whey protein suitable for many individuals who are lactose intolerant.

  8. Supports Healthy Aging: Maintaining muscle mass is important for overall health, especially as people age. Whey protein can be beneficial in supporting muscle preservation and preventing age-related muscle loss.

  9. Convenient and Versatile: Whey protein is available in various forms, such as whey protein concentrate, whey protein isolate, and whey protein hydrolysate. It can be easily added to shakes, smoothies, or recipes, providing a convenient way to increase protein intake.

  10. May Improve Blood Sugar Control: Some studies suggest that whey protein may have a positive impact on insulin sensitivity, which could be beneficial for individuals with insulin resistance or type 2 diabetes.

Frequently Asked Question's

The liquid whey byproduct from the cheese-making process is filtered to remove virtually all bacteria as well as the majority of the fat and lactose content. It is then put through a second filtration process depending on the form of whey protein product. Once this secondary filtration has been carried out the liquid whey is then spray dried into a powder and then packaged.

Yes, our whey protein is sourced from dairy cows.

Yes, as you can see from our products’ nutritional information they have minimal carbohydrate per serving across our range, including Perfect Whey Protein.

If it contributes to you being in a calorie surplus then yes, whilst also having the added benefit of helping you maintain a desirable body composition.

Whey protein, like other protein sources, provides the building blocks needed to repair and rebuild muscle tissue. Research has also shown that it can help keep you fuller for longer and improve body composition.

There are three forms whey protein appears in; whey protein concentrate, whey protein isolate and whey protein hydrolysate. Concentrate is the most commonly found form, low in fat and lactose and high in protein (typically exceeding 70%), Isolates are further processed to remove all the fat and lactose (containing at least 90% protein). Hydolysates are slightly different; they are “pre-digested” by an additional processing step making them more rapidly absorbable comparative to the other forms.

Perfect Nutrition Serious Mass is your High Protein, High Calories Gainer designed to support your gaining goals. For desired results, take it along with your meals and snacks and not instead of it. For new consumers- please start with half a scoop and slowly work your way up to a full serving (2 scoops). When taken as directed, serious mass can help you achieve caloric surplus which is what gives you the Gains! And when combined with regular resistance exercise over a period of time it may support muscle building.

In short, Yes. Your body needs dietary protein regardless if you are trying to get fit, lose weight, build muscle, run a marathon, or even when you are sedentary. We all need protein. Protein works beyond muscle. Protein is essential for all healthy adults, active or not. It is needed to help many vital functions that take place in the body. Proteins can be used for body tissues, hormones, enzymes, antibodies, to transport oxygen, support the immune system, be used for energy and more. One must always try to eat a protein rich balanced diet, and in addition consuming high quality complete protein supplements is one way of meeting daily dietary protein requirements. Give your body the right tools to help it function optimally!

The amount of protein you need depends on you and your goals. Typically, a healthy adult should get 10 to 35% their total daily calories from protein. For the average healthy adult looking to maintain – consuming 0.8 to 1.0 grams of protein per kilogram of bodyweight per day spread across a few meals and snacks is suggested. For those with increased physical activity or strength training, they can increase intake upto 1.2 to 2.2 grams of protein per kilogram per day spread across a few meals and snacks. Example: A healthy sedentary adult weighing 68kg will need at least 68kg x 0.8g = 54 grams protein per day.

For Gold Standard Isolate and Performance Whey we use ultrafiltration- same is mentioned on the product label as well. At Perfect Nutrition we may use variety of highly sophisticated filtration processes such a ultrafiltration, nano-filtration, etc. All these methods may cause some denaturation of the protein which is perfectly normal. In fact, cooking also causes denaturation ( e.g: eggs become hard upon boiling due to protein denaturation). Contrary to a lot of misinformation floating on internet, these filtration methods do not impact the ability of the Whey Protein when it comes to training recovery. 

Creatine is among the most researched supplements in the sports nutrition category over the last 20 years. There is no compelling scientific evidence that the short- or long-term use of creatine monohydrate has any detrimental effects on otherwise healthy individuals and the only side effect seems to be potential weight gain.

Sweeteners are used in foods to provide zero to reduced calorie options to sweeten foods. There is lack of convincing data linking the intake of sweeteners at appropriate daily intake levels – to any negative health outcomes . FSSAI permits use of artificial sweeteners and considers them to be safe for consumption at prescribed levels

If you have any pre-existing medical conditions you always want to consult with a medical professional prior to ensure the product is appropriate for you.

Generally, we do not recommend our products to anyone under the age of 18. For teenagers between the ages of 15-18, please consult with your pediatrician prior to use.

No, the proteins that we use in our products are made using either synthetic or fungally derived rennet.

What you are seeing is completely normal. Not all ingredients are the same level of granulation or precipitation of free-form amino acids, so at times and depending on how well mixed, there can be some visible fall-out. You can continue with your method of mixing to make it a bit more homogenous. Hope that helps!

Amino Acid profile means content and distribution of the different amino acids found in a protein. It does not change from brand to brand, or region to region, as the protein source itself (in present case-Whey) has a standard amino acids profile. Only case the profile may change is if the manufacturers are “Adding” or “Enriching” the product with added amino acids. Which is not the case with Gold Standard Whey. One serving of Gold Standard 100% Whey has 11 grams of naturally occurring Essential Amino Acids (including 5.5 grams of BCAAs), and over 4 grams of naturally occurring Glutamine and Glutamic Acid. Product label is a limited space so we chose to remove individual amino acids distribution since it is essentially a common knowledge that can be found anywhere in public domain. Below is typical amino acid profile of Whey Protein.
