The Claim
Long-term administration of selenium nanoparticles (50 μg Se/kg/day for 24 weeks) in apolipoprotein E-deficient mice fed a high-fat diet is associated with increased atherosclerotic lesion size, reduced antioxidant enzyme activity, and elevated markers of oxidative stress.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In apolipoprotein E-deficient mice on a high-fat diet, daily selenium nanoparticle supplementation at 50 μg Se/kg for 24 weeks is associated with larger arterial plaques, lower antioxidant enzyme levels, and higher oxidative stress markers.
See the scientific wording
Long-term administration of selenium nanoparticles (50 μg Se/kg/day for 24 weeks) in apolipoprotein E-deficient mice fed a high-fat diet is associated with increased atherosclerotic lesion size, reduced antioxidant enzyme activity, and elevated markers of oxidative stress, suggesting a potential for cardiovascular harm under these specific experimental conditions.
Selenium nanoparticles enter the body and settle in the liver and blood vessels, where they block the body's natural antioxidant enzymes and damage the liver's ability to manage fats. This causes harmful fats and reactive chemicals to build up in the blood, which stick to artery walls and form larger, unstable plaques.
What the research says
1 studyIn mice that easily get clogged arteries and are fed a fatty diet, giving them selenium nanoparticles for six months made their artery plaques worse and reduced their body’s natural defenses against damage — meaning it hurt them, not helped.
