We all like to romanticize with the idea that beef protein is filet mignon grinded into powder, but it is simply not. The price of beef is exuberant, making this impossible. 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. Now these sound fancy, but what exactly are they? Hydrolyzed Beef Protein Isolate is also known as
Collagen. Collagen is not a complete protein source, and is high in glycine, proline, arginine, and hydroxyproline. All these labels are just fancy words for what beef protein really is: collagen, gelatin, and left over scraps.
The first thing you should notice is the glaring similarities between beef protein isolate and gelatin. They are nearly identical, so for the purposes of comparisons between whey and the other two, we will simply compare whey vs. beef protein isolate. Remember, we are not comparing whey protein isolate to a steak dinner here! This is a comparison of “beef protein powders” to whey protein powders.
Another 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). Glycine is a filler amino acid added into products to cheapen the cost of the product. Glycine comes up on lab tests that test for protein content based on nitrogen content as protein, which allows companies to pad the amount of protein in their product by stuffing them with glycine.
