I've become a distributor for Max International after doing a heap of research. Not interested in a slugfest, I'll give you the guts of the science, and a bit of the background so you can do your own research and make up your own mind :)
MaxONE contains the ingredient D-Ribose-L-Cysteine, a cysteine pro-drug, which goes by the name RiboCeine. There is no glutathione in the products. As the others have stated whole glutathione supplements are practically worthless.
First and foremost the independent research, 20 published articles over the last 25 years, funded by the National Institutes of Health, the Veterans Administration and more:
I also recommend the patent, it's probably the best science overview of it, and references a number of the other published articles on it:
See Table 1 for the "300% more effective than NAC" claim. Note the 1.3x increase with NAC was a concentration 2.5 higher than the RiboCeine, which produced a 1.7x increase.
That kinda answers the question of "is there a cheaper no-name variety one should look at?" Not until the patent expires.
Also studies have shown RiboCeine supports GSH levels in the kidneys better than NAC
There is evidence in humans that administration of N-acetylcysteine will reverse or prevent acetaminophen-induced liver injury, but it does not always antagonize kidney injury (Davenport & Finn 1988). Unlike N-acetylcysteine, Ribose Cysteine is a cysteine prodrug that antagonized acetaminophen-induced target organ injury in both liver and kidney (Roberts et al. 1992; Lucas et al. 2000).
A little more background to support the "best thing since sliced bread" claim :P RiboCeine was created by Dr Herbert Nagasawa. A few career highlights:
- Senior Editor of the Journal of Medicinal Chemistry for 32 years
- Published over 165 papers in peer-reviewed journals
- Ad hoc grant reviewer for the NCI and NIAAA, National Institutes of Health
- Senior Career Research Scientist for the Veterans Administration
- Creator of the new 3-minute cyanide antidote for the US Department of Defense
25 years ago he initially developed it for alcoholic Vietnam War vets to protect their liver while working at the Veterans Administration. He was onto glutathione long before before most, and as you can see not just in the role of GSH, but also the chemistry of increasing glutathione.
Dr Nagasawa actually missed the his first RiboCeine product launch event at Max International in 2010. He was at the National Institutes of Health-Homeland Security 4th Annual Countermeasures Against Chemical Threats Network Symposium to presenting his work on the cyanide antidote.
If you don't think Dr Nagasawa knows what he's doing when it comes to glutathione, then don't ask me cause I ain't got nothing compared him! :)
FYI the Cellgevity product (http://www.getmaxed.net/max-cellgevity) is the one to get now, not MaxONE. It has the same amount of RiboCeine plus 12 other ingredients, including a bunch which are known to be Nrf2 activators, which increases the various gluathione enzymes. That's a whole other interesting topic :)
As for my experience, I noticed something in a few days. Have friends and family on it who like what it does for them. Plenty of big name athletes and doctors using it (http://www.getmaxed.net/who-has-taken-cellgevity). Hope that gives you the info you're after.
