Details

NIGHTTIME & BETWEEN-MEAL RECOVERY - 24g of premium micellar casein protein per serving to support muscle recovery during nighttime and between meals. Its slow-digesting protein provides a convenient protein option when you go longer periods without food, such as during sleep.
100% MICELLAR CASEIN - Every gram of protein comes from micellar casein, a milk-derived protein that digests more slowly than whey. Ideal for anyone looking to add quality, slow-digesting protein to their daily nutrition and exercise routine.
ESSENTIAL AMINO ACIDS - 9g of naturally occurring essential amino acids (EAAs) per serving to support muscle recovery and help you get more from your protein intake.
MAGNESIUM & ZINC - An excellent source of magnesium and zinc, with 85mg of magnesium and 11mg of zinc per serving. A convenient way to add these important nutrients alongside your daily protein intake.
ANYTIME PROTEIN - A great choice 30–60 minutes before bed or anytime you want to boost your protein intake, including between meals. Suitable for fitness enthusiasts and athletes at every level as part of a balanced diet and exercise program.
EASY MIXING, SATISFYING TEXTURE - Enjoy a satisfying, creamy texture with easy mixing using only a glass and spoon. Mix one scoop with 8–14 fl oz of cold water, milk, or your favorite beverage; use less liquid for a thicker shake or more for a thinner consistency.
