Just had a blood test and my AST & ALT levels are slightly elevated. I haven’t drunk in 24 years, never used steroids etc.

A quick bit of research revealed that liver enzyme elevation is common after heavy exercise.
I supplement with glutamine, creatine and protein also which could also elevate certain liver markers.

The bottom line is don’t freak out over slightly elevated liver enzymes. If you want to make certain – stop supplementing and working out for a week then re-test.

My test was for the army so I will only do a re-test if they request it.

Heres a great medical study on the subject:
