I've done a bit more reading on alpha-ketoglutarate, a natural component of the Krebs biochemical cycle that generates body energy and whose levels normally decline with aging. It was the subject of a recent post pointing to studies indicating the positive effects of its supplementation on health and longevity in mice. So...I have started taking 300 mg capsules of the stuff with my other breakfast supplements. I decided to pass on the pricey 'Rejuvant Life Tabs', containing 1000 mg and offered by Ponce de Leon Health, a company set up by some of the researchers, and instead got the compound from Kirkman, one of the supplement providers. I'm inclined not to be too paranoid about their sending sawdust instead of the real product. I noted that I could buy the >98% pure dry powder from the Sigma-Aldrich company, the supplier my biochemisty lab used for over 30 years, but decided the hassle of dealing with bulk powder wasn't worth it. The compound is quite acidic, so best taken as the Calcium or Magnesium salt and with a meal. I had an unhappy tummy when I tried it without food.
I will continue taking the compound, will report imagined positive or negative effects as addenda to this post. Undesirable side effects will lead me to discontinue the supplement, as was the case with my 2010 (Acetyl L-carnitine, alpha-lipoic acid, and the B-vitamin biotin) and 2016 (pterostilbene and nicotinamide riboside) self experiments. The latter, like a 2008 experiment with resveratrol was terminated because of increasing arthritic symptoms. The 2008 post had 33 comments reporting negative effects resveratrol.
And, a necessary comment regarding Ponce de Leon Health and other purveyors of life extension elixirs:
You're gonna die..there is compelling evidence that none of us will make it past ~120 years of age.
