<<Disclaimer: Verify this information before applying it to your situation.>> I know all of us with Leaky Gut are supposed to take this (along with a good probiotics!) . Two questions: 1) MY L-glutamine is called L-glutamine PAK -pyridoxal Alpha-ketoglutarate - what does this do? As I understand it is an amino acid - but the PAK part is not in every LGlutamine on the market. 2) I am to take mine on an empty stomach - I have read some of you to take it at meals. What's the difference? Any light to be shared would be great. Sally Hackett, Raleigh NC
