Micellar Casein
What is Micellar Casein?
Micellar casein is a slow-digesting protein derived from milk. It is produced by separating casein from whey and other components of milk, forming micelles that allow for gradual nutrient absorption.
It is often used in protein supplements due to its ability to provide a sustained release of amino acids, making it popular for use before bed or in meal replacement shakes to support muscle maintenance over time. The evidence indicates it can be useful for muscle recovery and growth, particularly when consumed in conjunction with exercise.
When you see micellar casein on a label, it generally indicates a focus on long-term protein supply rather than quick absorption, which might appeal to people looking to stave off muscle protein breakdown over several hours.
Commonly found in: protein supplements, meal replacement shakes, sport nutrition products
Benefits
- Provides a sustained release of amino acids, supporting muscle maintenance.
- Can aid in muscle recovery and growth, especially when used alongside exercise.
Micellar casein is generally recognized as safe (GRAS) when used in accordance with good manufacturing practices.
Research supports its role in maintaining muscle mass and promoting recovery due to its slow digestion.
Micellar casein is animal-derived and not suitable for a vegan diet.

Scout's take
Slow-digesting native casein with intact micellar structure; provides a sustained-release amino acid profile that complements the fast-digesting whey fractions.
More from Scout's analyses
Micellar casein is a milk derivative used as a protein source, generally neutral but not necessarily beneficial for all consumers.
