I was running around pub med doing some searches and came across this: http://www.ncbi.nlm.nih.gov/entrez/...uids=16098029&query_hl=12&itool=pubmed_DocSum The study claims... although I couldn't get the full text: " Mitochondrial mutagenesis as well as functional consequences could be normalized by increasing intracellular creatine levels. These data indicate that increase of the energy precursor creatine protects from functionally relevant, aging-associated mutations of mitochondrial DNA." Anyone have access to the journal? My school doesn't and I can't get the full text. Its Nature Publishing Organization. Sounds pretty cool if it's actually true... even more reason to take creatine.
