My elderly dog is sleeping more and much less active and alert so I was very interested when my vet prescribed a new supplement for her. The ingredient list piqued my interest even more. It includes: DHA/EPA N-Acetyl cystine Acetyl L - carnitine CoQ10 Fascinating that my vet should be prescribing the kinds of things that we're interested in here, while my GP would be scratching his head. Edited - if anyone wants to read about it here's a link: http://www.vetplusglobal.com/products/aktivait/ As canines metabolize things differently to us it probably wouldn't be suitable for humans. Would love a human version!
