What about ornithine a-ketoglutarate?
Good find. I can't wrap my head around it all atm so maybe someone else may elucidate.
I remember ornithine works for scavenging/converting ammonia to urea and that less ammonia spares a-KG for more energy from the TCA. Then ornithin-aKG could be doubly beneficial.
It would be great if anyone can find the equivalent study to this study Intermediary metabolism of the human hair follicle but done on the dermal papilla.
According to this ex vivo/in vitro study the human hair follicles (and skin) mainly rely on
So glutamine and glucose seem to be an equally important energy substrates for hair follicles.
Replacing the 1% glucose with 1% L-glutamine may be an option. Or using both L-Glut and glucose in combination, which in the study above lead to much higher follicle ATP content than only glucose (in case that higher ATP content is a good thing and not sign of a backlog).
Yet I'm thinking that feeding other substrates (like a-KG) directly into the mitochondrial TCA of skin or hair follicles could unleash significant, additional metabolic energy capacities.
