Interesting, happen to have a link to these articles, I'm rather curious now.
Also, I found this on the web...
"creatine supplementation was associated with a 27% decrease in homocysteine. This is because creatine supplementation downregulates GAA biosynthesis, thus decreasing methylation demand."
So, would this mean that supplementing with creatine would help counter balance the effects of the glycocyamine?
