Betaine Reverses IR and NAFLD

Borgschulte et al (2008). "Betaine Treatment Reverses Insulin Resistance and Fatty Liver Disease Without Reducing Oxidative Stress or Endoplasmic Reticulum Stress in An Animal Model of NAFLD." Gastroenterology 134(4): A414.

Compared to a control diet, a high fat diet led to increased:

- body weight
- plasma insulin and homocysteine
- liver injury
- oxidative and endoplasmic reticulum stress

Addition of betaine (1.5%) to the high fat diet reduced:

- body weight
- plasma insulin and homocysteine
- liver injury
