In middle-aged women with low micronutrient levels, taking a daily supplement containing vitamin D3, vitamin K2, vitamin B6, vitamin B12, and magnesium for 12 weeks lowers LDL cholesterol without...
Mechanism
Synthesis from 1 study
Vitamin K2 and magnesium stop bad cholesterol from getting damaged and help the body remove it faster. B vitamins and magnesium lower a harmful substance that causes inflammation and fat buildup, which tells the liver to make less bad cholesterol. This is why only LDL goes down, not the other fats.
Most probable mechanism
Vitamin K2 and magnesium work together to stop bad cholesterol from getting damaged and help the body remove it faster, while B vitamins and magnesium lower a harmful substance that causes inflammation and fat buildup, leading to less bad cholesterol in the blood.
Vitamin K2 activates matrix Gla protein, which inhibits calcium deposition in arterial walls and reduces oxidative stress in the arterial intima.
Reduced oxidative stress decreases oxidation of LDL particles, making them less likely to be trapped in artery walls and more available for clearance.
Magnesium enhances lecithin–cholesterol acyltransferase activity, promoting cholesterol efflux from peripheral tissues to HDL particles for transport to the liver.
Vitamin B6 and vitamin B12 act as coenzymes in homocysteine metabolism, converting homocysteine to cysteine and methionine, thereby lowering circulating homocysteine levels.
Lower homocysteine reduces endothelial inflammation and suppresses hepatic production of C-reactive protein.
Reduced systemic inflammation decreases hepatic synthesis of apolipoprotein B-100, the core protein of LDL particles.
Magnesium improves insulin sensitivity in skeletal muscle, reducing glucose flux into adipocytes and limiting de novo lipogenesis.
Lower visceral fat mass reduces secretion of pro-inflammatory cytokines that stimulate hepatic LDL production.
