Glycine is a filler amino acid added into products to cheapen the cost of the product. These are the amino acids that aid in recovery, muscle protein synthesis, etc.Īnother massive difference is the amount of glycine in beef protein (beef protein isolate contains 20.1 grams of glycine, more than 14 times the amount of glycine in whey protein). The amount of essential amino acids and BCAAs are what we really want to consider when we look at different sources of protein as athletes when it comes to determining what is best for our lifestyles. 19.4 grams in beef protein isolate per 100 g).

Now these sound fancy, but what exactly are they? Hydrolyzed Beef Protein Isolate is also known as Collagen.
A quick search on the internet shows that the top 5 selling beef protein products contain the following ingredients: Hydrolyzed beef protein isolate, Hydrolyzed gelatin. The price of beef is exuberant, making this impossible. We all like to romanticize with the idea that beef protein is filet mignon grinded into powder, but it is simply not.
The important question however, is: what is beef protein powder? Beef is quite a broad term. By now you may have seen “beef protein powder” advertising that it is a suitable alternative to milk and whey based proteins.
