Background:

• Magnesium and vitamin E (VE) have distinct roles in metabolic health, with both showing benefits in diabetes management.
• Understanding their combined effects on lipid metabolism and blood viscosity is crucial for developing effective nutritional strategies.

Purpose of the Study:

• To investigate the effects of combined preventive supplementation of magnesium and VE on lipid peroxidation, lipid parameters, and blood viscosity in a rat model of diabetes.
• To compare the efficacy of combined supplementation versus individual nutrient supplementation.

Main Methods:

• Rats were fed high-energy diets for 8 weeks and divided into six groups: control, VE alone, middle-dose magnesium, high-dose magnesium, VE plus middle-dose magnesium, and VE plus high-dose magnesium.
• Evaluated malondialdehyde levels, total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and blood viscosity at middle and high shear rates.

Main Results:

• Combined VE and magnesium supplementation significantly reduced malondialdehyde levels compared to controls.
• Total cholesterol and LDL cholesterol were reduced, while HDL cholesterol was elevated in various treatment groups, particularly with combined supplementation.
• Blood viscosity was significantly improved across all treatment groups compared to the control group.

Conclusions:

• Preventive supplementation with vitamin E combined with magnesium demonstrated superior benefits in improving plasma lipid profiles and blood viscosity in diabetic rats compared to magnesium alone.
• No significant interaction was observed between magnesium and vitamin E, suggesting additive or synergistic effects.
