Frequently asked questions

Critical Whey

What is the best protein powder for building lean muscle?

The best protein powder for building lean muscle is one that provides a high amount of complete protein, contains all nine essential amino acids, and is easy to consume consistently alongside resistance training. Whey protein for lean muscle is widely recognised as one of the most effective options because it is naturally rich in branched-chain amino acids (BCAAs), including leucine, which plays an important role in stimulating muscle protein synthesis. Critical Whey delivers 24g of protein per serving from a blend of whey protein concentrate, whey protein isolate, hydrolysed whey protein and milk protein concentrate. This combination provides fast-absorbing, high-quality protein that supports muscle growth, recovery and the maintenance of lean muscle when combined with regular training and a balanced diet. Its smooth texture and wide choice of flavours also make it easier to meet daily protein goals consistently.

How much protein do I need after a workout?

Most active weightlifters and athletes aim to consume around 20-40g of high-quality protein after resistance training, depending on body size, training intensity and total daily protein requirements. Meeting your overall daily protein intake is generally more important than the exact timing, but consuming protein soon after training is a practical way to support recovery and muscle maintenance. Each serving of Critical Whey provides 24g of complete protein, making it an effective post-workout option for athletes, gym-goers and anyone looking to increase their daily protein intake conveniently.

When is the best time to drink a protein shake for muscle growth?

The best time to drink a protein shake is whenever it helps you consistently achieve your daily protein target. Many people choose to have a whey protein shake shortly after training because it is convenient and rapidly digested, while others use it between meals or as part of breakfast to increase protein intake throughout the day. Critical Whey works immediately after exercise or at any point during the day when additional protein is needed to support recovery, muscle growth and daily nutrition goals.

Is whey protein good for beginners?

Whey protein is great for both beginners and experienced athletes. Protein requirements increase with regular exercise, and many people find it challenging to consume enough through food alone, particularly when starting a new training split. Critical Whey is formulated for a mixable and great-tasting product in a wide variety of flavours, making it a practical protein powder for beginners, experienced lifters and athletes to use consistently as part of their nutrition plan.

Is whey protein a good choice if I’m trying to build muscle while staying lean?

Yes. Whey protein is commonly used during lean muscle-building phases because it provides high-quality protein without requiring large amounts of additional calories. Increasing protein intake while following a structured strength-training programme can help support muscle growth and maintenance. Critical Whey provides 24g of protein with only around 120 calories per serving, making it suitable for athletes and gym-goers who want to increase protein intake while managing their overall calorie consumption.
