Gold Standard 100% Casein is a high quality and high purity casein protein powder. Unlike whey protein, casein is digested very slowly, which makes it a great way to provide your body with a steady flow of amino acids when you’re not eating. Right before bed would be an excellent time to consume Gold Standard 100% Casein. Gold Standard 100% Casein is an honest and simple supplement. It is primarily made up of micellar casein and very little else. In each 32 g serve, you get 24 g protein, only 1 g fat, 3 g carbs, and no sugar. Beyond these basics, you are also looking at around 5 g of BCAAs and 5 g of glutamine. These are all great amino acids to help with recovery.
