Several studies have reported that probiotics could modulate host lipid metabolism via altering the intestinal microbiota. Hence, the current study was aimed to assess the efficacy of a mixture of probiotic-contained milk formula (PMF) with three different bacterial strains [Lactobacillus acidophilus (La5), Lactobacillus casei (TMC), Bifidobacterium lactis (Bb12)] on lipid profile and intestinal function in healthy mild hypercholesterolemic volunteers. Totally, 40 healthy mild hypercholesterolemic subjects (180–220 mg/dL) were randomly assigned into two groups as placebo or experimental group. All the subjects were requested to drink either PMF (experimental) or skimmed milk drink formula-placebo (30 g mixed with 200 mL of water) for 10 weeks and continued by 2 weeks of the follow-up period. Supplementation of PMF for 10 weeks significantly improved (p < 0.05) the fecal weight, fecal movement (decreased fecal gastrointestinal passing time) by improving intestinal microbiota (increasing beneficial bacterial species like Lactobacillus, Bifidobacterium spp.), and lag time of low-density lipoprotein (LDL) oxidation. Also, intake of PMF substantially reduced (p < 0.05) the levels of total cholesterol (TC; 8.1%) and low-density lipoprotein cholesterol (LDL-c; 10.4%) and thus showcasing its cardioprotective efficacy. PMF considerably improves gastrointestinal function by modulating fecal movement, intestinal microbiota, and decrease cholesterol and might be helpful in the management of hypercholesterolemia.
