What is MPS or Muscle Protein Synthesis and Why Does it Matter?

Let’s start with some glossary terms.

• Protein Turnover is the perpetual tearing down and building of new proteins for the body
  • Without this process our cells would eventually become weakened and damaged
  • MPS is the building of new proteins
  • MPB is the breakdown of old proteins
  • Net Balance is the difference between these two processes

That’s great, but how does that make me more muscular and leaner?

• We want MPS most of the time (although we do want MPB to “clean out the bad proteins”)
• EAAs are the most efficient ways to stimulate MPS (Any protein with EAAs in it will stimulate this)
• The actual EAA ratio has an impact on how strong the MPS response is
• The total EAAs also have an impact on how strong the MPS response is
• 20g of Whey has been shown to be near maximal MPS response (The Muscle Protein Synthetic Response to Meal Ingestion Following Resistance-Type Exercise | SpringerLink)
• Doubling this amount only raises the MPS Response another 10%-20%
• When EAAs are matched with whole protein sources, the MPS response is matched
  • Whole proteins have other things besides EAAs (NEAAs)
  • There are 10.6g to 25g of Whey Protein Concentrate
  • Just using EAAs offer a much more effective dose
• But that’s just part of the story.
  • AM.AMINO uses a ratio that has been shown to be utilized at 5X the rate of Whey
  • NB is measured simply by measuring how much nitrogen comes in, subtracted from how much comes out of the bodily waste products
  • AM.AMINO ratio is utilized at 99% (https://pubmed.ncbi.nlm.nih.gov/9882831/)
  • That means 99% of the dose goes to MPS not to waste!
• Having a Positive MPS is the way to be in a caloric deficit and not lose muscle mass
  • This is why you hear so many protein recommendations for deep caloric cuts
  • However, all that protein adds up in calories itself
  • AM.AMINO allows you to hit those protein requirements without all the calories!
