Cholesterol plays a crucial role in the body, but its accumulation in the liver can lead to significant health issues. Cholesterol overload in the liver has been linked to oxidative stress, DNA damage, and the progression of liver diseases such as non-alcoholic fatty liver disease (NAFLD) and hepatocellular carcinoma . Excessive cholesterol can impair mitochondrial and lysosomal functions, leading to inflammation, fibrosis, and steatosis in the liver.
Cholestasis, a condition characterized by the accumulation of bile acids in the liver, can be induced by various drugs, including dietary supplements . This condition can lead to liver damage, fibrosis, and cirrhosis due to the toxic effects of accumulated bile acids . The mechanisms of drug-induced cholestasis involve both deteriorative responses, such as bile acid accumulation, and adaptive responses aimed at mitigating this accumulation.
Dietary supplements, including those aimed at lowering cholesterol levels like CholestOff, have been implicated in cases of liver toxicity. The hepatotoxicity associated with these supplements can manifest as cholestatic liver injury, which is characterized by the obstruction of bile flow and subsequent liver damage . The risk of liver injury from dietary supplements is often idiosyncratic, making it difficult to predict and detect in clinical trials.
The pathogenesis of cholestatic liver damage involves complex interactions between genetic, mechanical, and toxic factors that impair bile secretion and lead to the accumulation of bile acids in the liver. This accumulation triggers oxidative stress and inflammation, further exacerbating liver damage . The body's adaptive mechanisms, such as alterations in bile acid transport and detoxification, are often insufficient to prevent liver injury in cholestasis .
While CholestOff and similar dietary supplements are designed to manage cholesterol levels, they carry a potential risk of liver damage, particularly cholestatic liver injury. The accumulation of bile acids and cholesterol in the liver can lead to oxidative stress, inflammation, and fibrosis, contributing to severe liver conditions. Therefore, it is crucial to monitor liver function and consult healthcare professionals when using such supplements to mitigate the risk of liver damage.
