Each scoop provides 20.3 g of protein from a blend of whey protein isolate, whey protein hydrolysate and whey protein concentrate, with no added soy protein. This blend delivers all nine essential amino acids, including approximately 4.4 g of naturally occurring branched-chain amino acids (BCAAs), which play an important role in muscle protein synthesis (the process of building muscle) and recovery. BlueLab 100% Whey Protein is also suitable for lacto-vegetarian diets and contains Tolerase L, a lactase enzyme that helps break down lactose, which may improve lactose digestion in individuals who have difficulty digesting lactose.

How does it work?

Dietary protein provides the building blocks needed to repair and build muscle tissue after exercise. Whey protein is naturally rich in leucine, one of the key amino acids responsible for stimulating muscle protein synthesis. Because whey is rapidly digested and absorbed, it provides a quick supply of amino acids to the muscles, making it particularly useful after resistance or endurance exercise.

BlueLab 100% Whey Protein combines three different forms of whey protein, each offering unique characteristics: 

• Whey protein isolate is a highly purified source of protein with very little carbohydrate or fat
• Whey protein hydrolysate has been partially broken down into smaller peptides, allowing for faster digestion and absorption.
•  Whey protein concentrate provides high-quality protein while also contributing to the product’s creamy texture and naturally occurring nutrients.

Research consistently shows that consuming enough protein throughout the day is one of the most important factors for supporting muscle maintenance, recovery and growth. While including protein after exercise is a convenient way to support recovery, meeting your total daily protein requirements is even more important. 

Who is it best suited for? 

BlueLab 100% Whey Protein may be a good choice for: 

• Individuals looking to support muscle growth and recovery after resistance training.
•  Recreational exercisers and athletes aiming to increase their daily protein intake.
•  People who struggle to meet their protein requirements through food alone.
•  Individuals following a higher-protein eating pattern.
• Those looking for a concentrated protein source without the additional carbohydrates and fats found in more nutritionally complete products.
• Individuals following a lacto-vegetarian eating pattern who are looking for a convenient, high-quality protein source.

When would I choose BlueLab 100% Whey Protein?

BlueLab 100% Whey Protein is particularly useful when your priority is increasing protein intake rather than replacing a meal. Practical ways to include it in your day include: 

• After a gym or sports training session to support recovery.
• Blended into a fruit smoothie for an on-the-go breakfast.
• Mixed into oats to increase the protein content of breakfast.
• Stirred into plain Greek yoghurt for a satisfying protein-rich snack.
• Between meals on busy days when it’s difficult to reach your daily protein target through food alone.
