What is Casein?
Casein is a slow-digesting protein naturally found in milk, making it ideal for extended muscle support and recovery. Unlike fast-absorbing proteins, casein protein releases amino acids gradually, providing a steady supply of nutrients to your muscles throughout the night or during long periods between meals. For those seeking lasting recovery, casein can be a powerful addition to your routine.
Is Casein protein good for building muscle?
Yes! Casein protein is particularly effective for muscle maintenance and growth due to its prolonged absorption rate, which helps prevent muscle breakdown over time. Many athletes use casein protein powder as part of their bedtime routine to ensure muscles are constantly fuelled.

Casein Protein FAQs
What is casein protein?
Casein protein is a type of protein that is found naturally in milk. It equates to about 80% of the protein in milk, cheese and yoghurt. This protein is made up of different fractions, one of which is known as micellar casein, while others include hydrolysate and casein blends. This slow digestion makes casein protein perfect for those who want sustained muscle building and recovery (Ajmera, A et al. 2023).
Is casein protein good for you?
Casein is a good option if you’re sensitive to whey and are looking for an option that is slow-releasing. Unlike other types of protein, casein protein is composed of micellar particles, which are known to digest more slowly in the body and provide a sustained release of nutrients over time. This slow digestion rate is what makes casein protein powder ideal for the evening and is a key reason why casein custard supplements are popular for desserts. Casein can provide a steady stream of amino acids to the muscles during the overnight recovery period. (Mawer, R. 2016).
Does whey protein powder have casein?
In general, there should be no casein in WPI or concentrate, as these formulas contain 100% whey proteins based on the method they are processed. However, certain protein blends may contain a combination of casein and whey, particularly if they are promoting a combination of fast and slow-releasing properties (Idaho Milk Products).
Does casein protein help you lose weight?
Casein protein is a suitable option if you’re looking to achieve certain body goals. This protein is found in milk and is commonly used as a supplement in the form of casein protein powder or custard casein protein supplements. The reason why casein protein can support your body goals is because it is a slow-digesting protein, which means it keeps you feeling full for longer periods of time. This can be especially beneficial if you’re somebody who snacks between meals. Additionally, protein has a higher TEF (thermogenic effect of food) rating, which can help you increase your metabolic rate after eating (Brown, M. 2017).
How long does casein protein take to digest?
Casein protein powder takes longer for your body to break down and assimilate than other types of protein like whey. So, how long does casein take to digest? It can vary based on factors like the size of your meal and your individual digestive system, but in general, casein can take anywhere from 6-7 hours to fully digest. This slow digestion makes it an ideal choice for meals or snacks before bedtime or for sustained energy throughout the day (Joy, J et al. 2018).
Is casein protein better than whey?
Ultimately, the best option will come down to your overall goals. One of the main differences between these two protein supplements is their absorption rate, with casein offering a more sustained release. If you’re looking for a sustained energy release throughout the day or sustained recovery benefits overnight, casein protein is the best option. If you’re trying to lower your appetite and achieve certain body goals, you may also prefer casein (San Juan, E. 2023).
