Amino Acids

Not too long ago I read a few studies regarding protein. I know, every muscle head in the world knows they need protein for tissue repair. But what most folks are not aware of is that as we age our bodies do not process protein as efficiently as we did when we were younger. For males its late thirties-early forties, for females, early to mid thirties.
Quick physiology lesson:
Protein breaks down into amino acids
Amino acids help all of out enzymatic functions including the break down of protein
Its a very bad cycle. We don’t break down protein to make amino acids so we can't break down protein.
There is an easy solution. Take an amino acid supplement. There are lots of them on the market. Find one that has essential and branched chain aminos and you will be fine.
If you want to take it to the next step, read the book The Edge Effect by Eric Braverman. He goes into detail on how amino acids (or lack of) effect our entire well being.
