Milk protein is one of the most complete protein sources available, containing both fast and slow-digesting proteins to support your training goals. Derived from cow's milk, it provides all nine essential amino acids your body needs but can't produce on its own.
Whether you're looking to increase your daily protein intake or seeking a versatile supplement to fit your routine, our range of milk protein products offers different formats and protein profiles to match your needs. From micellar casein for overnight recovery to whey-dominant blends for post-workout, there's a milk protein supplement for every goal.
Who Milk Protein Supplements Are For
Milk protein supplements work for anyone looking to boost their protein intake through a dairy-based source. Strength athletes and bodybuilders often use them to support their training programmes, whilst endurance athletes appreciate the sustained amino acid release from the casein component.
They're also practical for busy people who struggle to hit their protein targets through whole foods alone. If you're comfortable with dairy and want a complete amino acid profile that combines both fast and slow-digesting proteins, milk protein supplements offer an efficient solution.
When to Use Milk Protein
The timing depends on which type of milk protein you choose. Whey-dominant milk proteins work well post-workout when you want faster absorption, whilst casein-rich options like micellar casein are popular before bed due to their slower release of amino acids throughout the night.
Many people also use milk protein supplements between meals to maintain their protein intake throughout the day. The combination of whey and casein means you get both immediate and sustained amino acid delivery, making them versatile for various times in your schedule.
Milk Protein Benefits
Complete Amino Acid Profile
Milk protein contains all nine essential amino acids in significant amounts, making it a complete protein source. This means you're getting the full spectrum of building blocks your body needs from a single supplement.
Dual-Release Protein Blend
The natural combination of whey (fast-digesting) and casein (slow-digesting) proteins in milk provides both immediate and extended amino acid availability. This makes milk protein particularly versatile for different times of day.
High Protein Content
Milk protein supplements typically deliver 20-30g of protein per serving, helping you reach your daily protein targets efficiently. Protein contributes to the growth and maintenance of muscle mass1, making it valuable for those training regularly.
Naturally Rich in BCAAs
Milk protein is naturally high in branched-chain amino acids (BCAAs), particularly leucine. These amino acids are the building blocks of protein and are found in high concentrations in muscle tissue.
Popular Picks
Looking for slow-release protein? Micellar Casein delivers over 25g of premium casein protein per serving, making it ideal for taking before bed or during extended periods without food. The slow-digesting nature of micellar casein provides a sustained release of amino acids.
FAQs
What is milk protein powder?
Milk protein powder is a dairy-based supplement derived from cow's milk that contains both whey and casein proteins in their natural ratio (approximately 20% whey, 80% casein). It provides all nine essential amino acids and offers a combination of fast and slow-digesting proteins in a single product.
What's the difference between milk protein and whey protein?
Whey protein is extracted and isolated from milk, providing primarily fast-digesting protein. Milk protein, on the other hand, contains both whey and casein in their natural proportions as found in cow's milk.
This means milk protein offers dual-release benefits, with the whey component digesting quickly whilst the casein digests more slowly over several hours. Whey protein is typically chosen for rapid post-workout absorption, whilst milk protein provides more sustained amino acid delivery.
How do I choose the right milk protein supplement?
Consider your goals and when you plan to use it. If you want slower-digesting protein for overnight recovery or between meals, micellar casein offers predominantly slow-release protein. For a balance of fast and slow-digesting proteins, look for milk protein blends that maintain the natural whey-to-casein ratio.
Also check the protein content per serving, the flavour options available, and whether the product fits your dietary requirements. All our milk protein products display full nutritional information to help you make an informed choice.
Can I use milk protein if I'm lactose intolerant?
Most milk protein powders contain some lactose, as they're derived from cow's milk. However, the amount varies between products. Some people with mild lactose intolerance can tolerate milk protein supplements without issues, whilst others may experience digestive discomfort.
If you're lactose intolerant, you might prefer whey protein isolate, which has most of the lactose removed, or consider plant-based protein alternatives. Always check the product's nutritional information for lactose content and consider starting with a small serving to assess your tolerance.
When is the best time to take milk protein?
The best time depends on the specific milk protein product. Casein-dominant options like micellar casein are popular before bed due to their slow digestion, providing a steady release of amino acids whilst you sleep. This makes them practical for overnight recovery periods.
Milk protein blends that contain both whey and casein work well at various times throughout the day, including post-workout or between meals. Many people use them as a convenient way to increase their daily protein intake whenever it suits their routine.
How much milk protein should I take daily?
Your total daily protein needs depend on factors like your body weight, activity level, and training goals. General guidelines suggest 1.2-2.0g of protein per kilogram of body weight for active individuals, though this can vary.
A typical serving of milk protein powder provides 20-30g of protein. Most people use one to three servings daily as part of their total protein intake from both food and supplements. It's worth calculating your total protein intake from all sources to ensure you're meeting your individual requirements without excessive consumption.
What makes Myprotein's milk protein products different?
Myprotein's milk protein range is developed by expert nutritionists who understand the importance of quality protein sources. Our micellar casein undergoes minimal processing to preserve the natural structure of the casein protein, ensuring you get a high-quality product.
We also offer transparent nutritional information and third-party testing on many products. Several items in our range carry Informed Sport certification, meaning they've been tested for banned substances, which is particularly important for competitive athletes.
Can I mix milk protein with other supplements?
Yes, milk protein can be combined with other supplements as part of your nutrition strategy. Many people stack it with creatine, which increases physical performance in successive bursts of short-term, high intensity exercise2, or add it to blends containing vitamins and minerals.
Some athletes mix faster-digesting proteins like whey with slower-digesting casein to create their own custom protein blend. Just be mindful of your total protein intake from all sources and ensure you're not unnecessarily duplicating ingredients across multiple supplements.
Is milk protein suitable for vegetarians?
Yes, milk protein is suitable for vegetarians as it's derived from cow's milk, not from animal slaughter. However, it's not suitable for vegans as it's an animal-derived product.
Vegetarians who include dairy in their diet can use milk protein supplements as a convenient way to meet their protein requirements. If you're looking for plant-based alternatives, we also offer a range of vegan protein powders derived from sources like pea, brown rice, and hemp.
Are Myprotein's milk protein products tested for quality?
Yes, quality testing is an important part of our production process. Many of our milk protein products, including Micellar Casein, are available with Informed Sport certification, which means they've been tested by the anti-doping laboratory LGC for banned substances.
This certification is particularly valuable for competitive athletes who need assurance that their supplements comply with anti-doping regulations. All our products also undergo rigorous internal quality checks to ensure they meet our standards for protein content and purity.
