People are usually misinformed about casein powder and disregard it as a viable supplement, but actually it is just as effective as whey protein. Casein powder contains approximately 90% protein and is a rich source of BCAAs and minerals. It helps with muscle growth and recovery.
The primary difference between casein and whey is how slowly casein gets digested. Whey gets to our muscles faster, but casein can provide more overall protein because of its ability to slowly digest. The slow digesting casein actually helps reduce protein breakdown in our body thanks to the sustained supply of amino acids to muscle cells.
