Whats the latest on DMG-Dimethylglycine supplementation?

"If a supplement works it's banned.  If it's not banned, it doesn't work."

And a question for the forum, why do the supplement questions always come from people with only a few posts?

Looks like it's nothing more than a derivative of the amino acid glycine and a type of B12 vitamin.  There's better things to take and if you want to try a B12 vitamin instead?  

Not entirely true.  Beat Alanine as an example is a proven supplement that isn't banned.  BCAA's are another.  People really need to do homework however before putting just anything in their bodies though due to all the marketing hype.    

Sorry I usually am a lurker but couldnt find anything when I searched.  Is this a banned substance? I don't know.  I didn't buy the DMG I just went in looking for a protein powder and Recoverite. wanted to research first.  Hopefully someone with first-hand experience will respond.

Wouldn't it be a fair assumption that the average athlete's blood oxygen saturation is already in the high 90s? What does dimethylglycine increase it to, 125%?

Hit up the sales guy for references to the supporting research. I can get just about any peer reviewed papers that have been published since the '80s. I'll send them to you, if they exist.

Because they (we) are too busy training. 1000+ posts doesn't make you faster. 

This is an interesting question so I tried a search.  I have pretty good access to peer reviewed journals and I wasn't able to find anything in reputable medical journals, have you had any luck with a search?

Maybe not, but those 1000+ posts will make you faster than nearly every supplement being sold out there will.

The best research I could find after a cursory search seems to have been done by the Soviets on their athletes and cosmonauts. The supplement guy has its function totally wrong for sure. It has nothing to do with blood oxygen saturation. Apparently it can be made in our bodies from glycine (as mentioned in an earlier post), trimethylglycine, serine and probably other proteins. From what I can tell without going deeper, dimethylglycine has been shown to be involved in some fashion in oxygen utilization by mitochondria. However, supplementation only helped as much as dietary sources could, kind of like vitamin B shots only helping if you're deficient in B vitamins.
