Apple cider vinegar’s role in improving lipid profiles

This systematic review and meta-analysis examined the effects of apple cider vinegar (ACV) on lipid profiles and glycemic parameters, providing insights into its potential as a natural remedy for improving metabolic health. The study reviewed data from nine clinical trials, totaling 686 adult participants, focusing on key outcomes such as fasting plasma glucose (FPG), serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and glycosylated hemoglobin (HbA1C).

The results indicated that ACV consumption significantly reduced serum total cholesterol (−6.06 mg/dL), fasting plasma glucose (−7.97 mg/dL), and HbA1C levels (−0.50%), particularly in individuals with type 2 diabetes and those who consumed ACV for longer than eight weeks. However, there was no significant effect observed on LDL-C, HDL-C, or fasting insulin concentrations. The findings also suggested that lower doses of ACV (≤15 mL/day) were more effective in reducing lipid levels, and longer intervention durations yielded more pronounced results.

The study highlighted ACV’s potential as an adjunct therapy in managing dyslipidemia and hyperglycemia, though it also acknowledged the limitations, such as the variability in dosages, durations, and participant health conditions across the included trials. Further, some side effects like stomach irritation were reported. More high-quality clinical trials are needed to establish optimal dosing, long-term safety, and mechanisms of action.
