Abstract

BACKGROUND: Recent evidence suggests that inhibiting 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR), a key enzyme in cholesterol biosynthesis, has beneficial effects on lipid metabolism and blood pressure (BP), but detrimental consequences on glycemia. Nutraceuticals (NUTs) containing both Monacolin K (MK) and Morus alba have been shown to be more effective in lowering lipids compared to NUT formulations containing only MK. However, the effects of these NUTs on glucose homeostasis have not been fully determined.

METHODS: To evaluate the association between LDL-C-lowering therapy and glycemia in patients receiving NUT combinations with or without Morus alba, we analyzed data from a prospective, randomized, active-treatment controlled trial (NCT02898805), which enrolled 359 patients to compare the effects of a NUT combination containing MK alone (Formulation 1, F1; n = 170) versus one containing MK and Morus alba (Formulation 1, F2; n = 189).

RESULTS: Participants in the two treatment arms (F1 vs. F2) were comparable in terms of sex, age, metabolic parameters, and BP. After 3 months, both groups experienced significant reductions in LDL-C, fasting plasma glucose, HbA1c, and HOMA index. F2 treatment led to a significantly greater reduction in glycemic levels compared to F1 treatment (b = - 16, p < 0.001). Notably, a divergent trend emerged over time: an inverse relationship between LDL-C and glycemic levels was observed in the F1 group, while a significant direct association between LDL-C and glycemic levels was detected in the F2 group (b = 0.06, p = 0.002).

CONCLUSIONS: Taken together, our findings indicate that the treatment with a NUT combination containing Morus alba simultaneously reduces plasma levels of LDL-C and glucose.
