Insights

Malleable protein matrix (MPM), a fermented whey ingredient, significantly lowered triglyceride levels in individuals with hypercholesterolemia. Further research is needed to explore its effects on LDL-C and glucose metabolism.

Area of Science:

  • Nutritional Science
  • Biochemistry
  • Human Physiology

Background:

  • Malleable protein matrix (MPM) is a novel ingredient derived from fermented whey using Lactobacillus kefiranofaciens.
  • Animal studies suggest MPM may reduce serum lipid concentrations.
  • Human trials are necessary to validate these lipid-lowering effects.

Purpose of the Study:

  • To evaluate the efficacy of MPM in reducing lipid concentrations in humans with hypercholesterolemia.
  • To test the hypothesis that MPM exerts significant lipid-lowering effects.

Main Methods:

  • A randomized, double-blind, placebo-controlled trial was conducted.
  • 161 participants with hypercholesterolemia received either MPM (30 g/d) or placebo for 12 weeks.
  • Primary outcome was the percentage change in low-density lipoprotein cholesterol (LDL-C); secondary outcomes included triglyceride (TG) and high-density lipoprotein cholesterol (HDL-C) changes.

Main Results:

  • MPM treatment resulted in a 9.8% decrease in TG levels compared to placebo.
  • A significant TG reduction of 20.0% was observed in subjects with baseline TG ≥ 150 mg/dL.
  • LDL-C showed a marginal decrease of 1.5%, while HDL-C, blood pressure, and fasting glucose remained unchanged. Hemoglobin A1c showed a positive treatment effect.

Conclusions:

  • MPM demonstrates significant triglyceride-lowering properties, particularly in individuals with combined hypercholesterolemia and elevated TG levels.
  • The effects of MPM on LDL-C and glucose metabolism warrant further investigation.
  • MPM was well-tolerated with no severe adverse events reported.
