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.

Source: Long-term administration of low-dose selenium nanoparticles with different sizes aggravated atherosclerotic lesions and exhibited toxicity in apolipoprotein E-deficient mice.

In plain English

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.

Why this might work

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.

  1. Study: Long-term administration of low-dose selenium nanoparticles with different sizes aggravated atherosclerotic lesions and exhibited toxicity in apolipoprotein E-deficient mice.

    In 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.
