FAQs

Frequently asked questions about whey protein powder. 

What is whey protein powder? 

Whey protein powder is a dietary supplement made from the proteins found in whey, the liquid byproduct of cheese production. It is a high-quality protein source used to support muscle growth and recovery. 

What is whey isolate protein powder?

Whey isolate protein powder is a form of whey protein that undergoes further processing to remove most of the fats and carbohydrates, resulting in a powder with a higher protein content. 

How much protein is in whey powder?

The protein content in whey powder varies, but typically ranges from 15 to 30 grams of protein per serving. SIXSTAR Whey Protein has 30g of Protein per scoop and the casein powder has 24g of protein per scoop.   

How to use whey protein powder?

Whey protein powder can be mixed with water, milk, or other beverages. Alternatively, if you love some work in the kitchen, it can be added to recipes like smoothies or baked goods to increase their protein content. 

How is whey protein powder made?

Whey protein powder is manufactured through a multi-step process that begins with the collection of liquid whey, a byproduct of cheese production. This liquid whey undergoes filtration to eliminate fats, carbohydrates, and impurities.  

Subsequently, it is concentrated to increase its protein content, reducing its water content. The next step involves drying, where the concentrated whey is either spray-dried or drum-dried, effectively transforming it into a dry, powdered form.  

Typically, spray drying is the preferred method, involving the spraying of the liquid into a hot chamber, causing water to evaporate, leaving behind whey protein powder.  

 

Stringent quality control measures are then implemented to ensure the protein powder adheres to industry and regulatory standards, including checks for protein content, flavor, and the absence of contaminants. The outcome is a versatile and high-quality protein source suitable for a range of dietary and fitness requirements. 

How many calories are there in whey protein powder?

Different products and different flavors have different calorie counts. 100% Whey Protein Plus  has 180 calories per scoop. Whey Protein Fruit Loops and Frosted Flakes have 170 calories per scoop, and Casein Protein sits at a low calorie count of 130.  

What is the best whey protein powder for weight loss? 

The best whey protein powder for weight loss depends on your specific goals and dietary needs. Look for products with low sugar and calorie content. Our SixStar Whey Protein Powders come in different flavors and blends. Use the label to pick the right product for your needs. 

What does whey protein powder do?

Whey protein powder is a fantastic source of high-quality protein, rich in essential amino acids, which makes it a go-to for those aiming to build and repair muscles, especially after workouts. Not just that, it can aid in weight management by curbing hunger and reducing overall caloric intake when used as a snack or meal replacement.  

 

On top of its muscle benefits, whey protein is also known for its immune system support, thanks to its content of immunoglobulins and lactoferrin. Whether you're an athlete, fitness enthusiast, or simply someone looking for a convenient way to enhance your diet, whey protein powder offers an array of advantages for all walks of life. 

How long does whey protein powder last?

Whey protein powder typically has a shelf life of several months to a few years if stored in a cool, dry place and kept sealed. They must be consumed before the expiry/best before date. Read the label for details.  

How to drink whey protein powder?

To consume whey protein powder, mix the recommended serving size with water or another beverage of your choice and shake or stir until well blended. Whey protein powder can be mixed with water, milk, almond milk, or other liquids. It can also be blended into smoothies, oatmeal, or used in baking recipes.
