Abstract

OBJECTIVE:

Previous studies have indicated that supplementation with probiotics might improve lipid metabolism. The objective of the study was to evaluate the effect of supplementation with probiotic strains Lactobacillus curvatus (L. curvatus) HY7601 and Lactobacillus plantarum (L. plantarum) KY1032 on triglyceride (TG) and apolipoprotein A-V (apo A-V) levels.

METHODS:

A randomized, double-blinded, placebo-controlled study was conducted with 128 non-diabetic subjects with hypertriglyceridemia. Over a 12-week test period, the probiotic group consumed 2 g/day of a powdered supplement containing L. curvatus HY7601 and L. plantarum KY1032, whereas the placebo group consumed a powder lacking probiotics.

RESULTS:

After the treatment, the probiotic group showed an 18.3% (P < 0.001) reduction in TGs and increases of 21.1% (P = 0.001) and 15.6% (P < 0.001) in the apo A-V and LDL particle size, respectively. The probiotic group had a significant reduction in TGs (P = 0.040) and increases in the plasma apo A-V (P = 0.003) and LDL particle size (P < 0.001) compared with the placebo group. In the probiotic group, the reduction in the TG levels was negatively correlated with changes in the apo A-V and baseline TGs, regardless of the APOA5 -1131T > C genotype.

CONCLUSION:

The consumption of two probiotic strains for 12 weeks reduced TGs and increased the apo A-V and LDL particle size in hypertriglyceridemic subjects. This effect was more pronounced in subjects with higher levels of fasting TGs regardless of their APOA5 -1131T > C genotype.
