Carnitine palmitoyltransferase 1C promotes cell survival and tumor growth under conditions of metabolic stress

A 2016 study showed that exercise in mice induced an increase in BHB, which in turn would lead to upregulation of Bdnf gene expression in the hippocampus (Sleiman et al., 2016)

Acetyl-l-carnitine concentration increased by 43% after oral supplementation at a dose of 2 g/day, indicating that acetyl-l-carnitine partial absorption without hydrolysis or immediate re-acetylation also occurs [4, 39]
