I don't know much about creatine, how's that supposed to help change one's life ? Is it from your experience ? A quick search learned me it helps for physical activities of the explosive type.
For me its changed my life in terms of energy levels.
I have bad sleep apnea and have totally gotten off of prescription stimulants because of high dose creatine.
Creatine seems to have a strong postive effect on the brain when taken in doses higher than those taken for exercise.
Im not interested at all in creatine for exercise. Just google: "Creatine for sleep deprevation"
And as a vegan you dont get any creatine since you're not eating meat, so your body has to make it itself, which requires a ton of methylation and if you're like me and have bad genes for methylation (google MTHFR gene polymorphism) your body had a hard time with it as it is. So by supplmenting creatine you're reducing burden on your body greatly.
edit: I saw your other comment, if you want to give more information that would be helpful, thanks. https://news.ycombinator.com/item?id=48346947#48347768
