About this item
Product details
NutraBio Micellar Casein Protein Powder has a slow absorption rate into the bloodstream, which provides a steady stream of amino acids to muscle cells over 4-6 hours. This ensures positive nitrogen retention in muscles for much longer periods compared to whey protein. Casein is best taken at night or in combination with whey protein isolate after workouts to help provide sustained amino acid delivery during the two most crucial times of muscle growth: during sleep and post-training. NutraBio's Micellar Casein is a complete protein that supplies all of the essential amino acids in the amounts necessary for muscle growth and maintenance. Because of their unique time-released qualities, Caseins are considered anti-catabolic or muscle-protecting proteins.

Most protein powders have a chalky taste but this one didn't. It was delicious in water, added to my yogurt, or with almond milk. I am very particular with protein powders and this one seems to be one of the cleanest and purest ones out there. I highly recommend this product.

No funny aftertaste
My mom needs the extra protein. This is better than the premixed ensures and other similar brands. She actually likes the taste of these shakes. Not the aftertaste of so many of those.
