Ethanol metabolism produces toxic molecules such as acetaldehyde and ROS ( + /NADH ratio, changes in redox state, increased fat synthesis, hepatocellular damage, and other associated malfunctioning of metabolic activities ( Betaine supplementation was demonstrated to alleviate the alcohol-induced fatty liver in rats by improving hepatic lipid metabolism (i.e., decreasing the synthesis and increasing the catabolism) via suppression of diacylglycerol acyltransferases: DGAT1, DGAT2, sterol regulatory element binding proteins: SREBP-1c, SREBP-2, fatty acid synthase, and HMG-CoA reductase and overexpression of peroxisome proliferator-activated receptor coactivator (PGC)-1 in the liver and preventing the decline of adiponectin concentrations in serum and adipose tissue (Yang et al., 2017)

While both cofactors and coenzymes help an enzyme or protein function correctly, there are distinct differences between them
About 40% of women carry a variant in the PEMT gene, which normally helps the body make some of its own choline under the influence of estrogen.36 With this variant, that backup pathway is less effective, leaving women more dependent on dietary intake
