Choline is an essential nutrient that plays a significant role in fat metabolism, particularly in the liver. It is a precursor for phosphatidylcholine, a key component of very-low-density lipoproteins (VLDL) that are needed to export triglycerides from the liver. Without adequate choline, fat can accumulate in the liver, potentially leading to nonalcoholic fatty liver disease (NAFLD). Scientific studies in both animals and humans have demonstrated that choline deficiency results in impaired hepatic lipid export and subsequent fatty liver. For example, controlled human studies have shown that low-choline diets can induce signs of fatty liver and liver dysfunction, which are reversible upon choline repletion (Zeisel & da Costa, 2009).

While choline supplementation is clearly effective in preventing and treating choline-deficiency-induced fatty liver, evidence for its use in treating general "poor fat metabolism" in the absence of a deficiency is less robust. Some clinical trials suggest possible benefits of choline supplementation on liver health in specific populations, but there is limited evidence that it enhances overall fat metabolism or weight loss in healthy individuals. Therefore, its use is scientifically justified in the context of choline deficiency or certain liver conditions, but broad benefits for fat metabolism are less well-established. Overall, choline's role in fat metabolism is supported by a moderate level of clinical evidence, particularly for liver health.
