and gluconeogenesis is suppressed 38 in part due to depletion of pyruvate and lactate 39
Shown on the right: Nicotinamide and nicotinamide riboside are converted to nicotinamide mononucleotide by nicotinamide phosphoribosyltransferase (NAMPT) and nicotinamide riboside kinases (NRKs), respectively
Ubiquinone Ubiquinone (UQ), also known as coenzyme Q10, is synthesized within the body cells or can also be obtained from the diet (Quinzii et al., 2007) (Figure 5)
Eight studies had low risk of bias (61, 64, 71, 72), 11 studies had moderate risk of bias (63, 65, 68, 74, 75, 79) and 22 studies had high risk of bias (59, 60, 62, 66, 67, 69, 70, 73, 7678, 80)
