Pro Shake is a natural source of BCAAs. A 500 ml bottle of Pro Shake also contains 9 g of BCAA from a natural source. BCAAs are essential amino acids that cannot be synthesized by the body. They must therefore be provided through food. They represent nearly 30% of the proteins present in the muscles. Pro Shake is light and easy to digest. The effective Pro Shake formula contains no added sugar, making this creamy milkshake very digestible and easy to consume between meals. Thanks to its smooth texture and irresistible taste, Pro Shake can be enjoyed with unparalleled pleasure!
