Power your day with milk protein powder 

Milk protein powder has exactly what you’re looking for when you want to manage hunger, recover after an intense training session or simply get more protein into your diet. Absorbed gradually over several hours, milk protein delivers a long-lasting stream of amino acids to your muscles. This supports recovery over time and protects against muscle breakdown to make the benefits of your workout keep coming, even as you sleep. 

The slower digestion rate and rich protein content, means milk protein concentrate also makes a satisfying meal replacement option when blended with oats, fruit, or healthy fats. Use as an alternative to whey protein, or in tandem to elevate your endurance and improve your recovery times. Giving you around 24g of protein per serving, the sustained release helps support overnight recovery and is ideal for athletes and anyone with an active lifestyle. Take before bed to activate muscle repair and wake up feeling ready to go again.

Frequently Asked Questions

What is milk protein powder?

Milk protein powder is a protein supplement derived from skimmed milk. It typically contains two main types of proteins: casein and whey in their natural 80:20 ratio. Casein is a slow-digesting protein that provides a steady release of amino acids. Whey protein is more rapidly absorbed and is often used for post-exercise recovery. Milk protein powder offers a complete amino acid profile, supporting muscle growth, repair, and overall nutritional needs, and is commonly used by athletes, bodybuilders, and individuals wanting to achieve their fitness goals.

How is milk protein produced?

Milk protein is made by removing most of the fat and carbohydrates from cows milk through ultrafiltration and drying processes that transform liquid milk into a dry, concentrated form. 

  1. Fresh milk is collected and standardised to ensure consistent fat and protein content
  2. The milk is then pasteurised to eliminate any harmful bacteria
  3. A process called ultrafiltration separates the milk proteins from the lactose and water, enhancing the protein concentration
  4. The concentrated milk is spray-dried rapidly with hot air to remove the remaining moisture, forming a fine powder 

This process preserves the protein content and amino acid profile, and extends the shelf life, making milk protein powder a convenient and long-lasting protein source.

What are the benefits of milk protein powder?

Milk protein provides a great range of benefits, including:

  • Aids muscle growth - Rich in essential amino acids, milk protein helps repair and build lean muscle, making it ideal for post-workout recovery or general daily use
  • Slow-releasing - Primarily made up of casein, milk protein is digested steadily, providing a consistent stream of nutrients to muscles over several hours
  • Meal replacement base - The thick texture and slow digestion make milk protein a great choice for replacing meals or reducing hunger between them
  • Supports active lifestyles - Whether you're training, recovering, or simply have a busy life, milk protein fuels your body's with around 20-25g of protein per serving
  • Perfect before bed - Taken before sleep, it boosts overnight recovery, helping prevent muscle breakdown as you rest

Does milk protein help you build muscle?

Milk protein comes with a complete amino acid profile, which means it has all of the essential amino acids your body needs. Along with its slow release properties, milk protein provides your muscles with the nutrients they need to repair, recover, and grow. When consumed regularly alongside resistance training, milk protein powder is an effective supplement for building muscle.

Is milk the best source of protein?

Milk is one of the most complete natural sources of protein, offering all nine essential amino acids in perfect proportions. While no single source of protein is "best" for everyone, milk protein has increased bioavailability compared to other sources and is effective at building muscle. Other protein sources, such as diet protein and vegan protein also offer multiple benefits for those with specific dietary requirements.

What is the difference between milk protein powder and whey protein?

The main difference between milk protein and whey protein is how quickly they are digested and the protein composition:

  • Milk protein contains both slow-digesting casein and fast-digesting whey proteins
  • Whey protein is isolated for its fast absorption and is ideal immediately after workouts
  • Milk protein is best for sustained release, meal replacement, or overnight use

Can you take milk protein every day?

Yes, milk protein is safe for daily use and can be an easy way to hit your protein goals. Whether you're training, dieting, or have an active lifestyle, milk protein is a great supplement and source of nutritional support.
