Key ingredients 2
Micellar CaseinGood
Micellar casein is a high-quality animal-based protein that provides a complete amino acid profile, beneficial for muscle repair and growth. It is slowly digested, providing a sustained release of amino acids, which is ideal for prolonged protein synthesis. This makes it particularly useful for nighttime recovery or prolonged periods without food.
Benefits
Rich in essential amino acids and supports muscle maintenance and growth over extended periods.
Sunflower LecithinBad
Sunflower lecithin is used as an emulsifier to improve the mixability of the protein powder. While it is a more natural alternative to soy lecithin, it is still a processed ingredient that may not be necessary in a clean protein product. Its inclusion can be seen as a minor negative due to its processing and potential allergenic concerns.
Risks
May cause allergic reactions in sensitive individuals and is a processed ingredient.
Benefits
Improves the mixability and texture of the protein powder, making it easier to use.
