Summary
L-carnitine treatment reversed high-fat diet-induced hyperlipidemia and liver steatosis in rabbits. This study highlights L-carnitine
Area of Science:
- Biochemistry
- Cardiovascular Science
- Nutritional Science
Background:
- High-fat diets induce hyperlipidemia and hepatic steatosis.
- Carnitine metabolism is altered during dyslipidemia.
Purpose of the Study:
- To investigate the hypolipidemic effects of L-carnitine in rabbits fed a high-fat diet.
- To assess L-carnitine's impact on liver steatosis and carnitine levels.
Main Methods:
- Rabbits were fed a high-fat diet for 8 weeks, followed by 4 weeks of L-carnitine treatment.
- Plasma lipid profiles, carnitine levels, and liver enzyme activities were analyzed.
Main Results:
- L-carnitine treatment significantly reduced plasma total cholesterol, triglycerides, and VLDL-associated lipids.
- Hepatic steatosis was reduced, and liver carnitine content was normalized.
- L-carnitine normalized plasma carnitine levels and modulated liver enzyme activities.
Conclusions:
- L-carnitine demonstrates significant hypolipidemic and anti-steatotic effects in a rabbit model of diet-induced dyslipidemia.
- Carnitine supplementation may be beneficial in managing hyperlipidemia and non-alcoholic fatty liver disease.
