The Claim
Blood selenium concentrations above approximately 150 µg/L are associated with elevated triglyceride and LDL cholesterol levels and reduced HDL cholesterol levels, indicating a biological threshold beyond which selenium negatively impacts lipid metabolism.
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.
When blood selenium levels exceed about 150 µg/L, triglyceride and LDL cholesterol levels are higher and HDL cholesterol levels are lower.
See the scientific wording
Blood selenium concentrations above approximately 150 µg/L are associated with higher triglyceride and LDL cholesterol levels and lower HDL cholesterol, suggesting a biological threshold beyond which selenium becomes detrimental to lipid metabolism.
When selenium levels get too high, the liver changes how it handles fats and cholesterol, making more bad cholesterol and fat particles, and less good cholesterol, which builds up in the blood.
What the research says
1 studyWhen people have too much selenium in their blood—above about 150 micrograms per liter—their 'bad' cholesterol and fat levels go up, and their 'good' cholesterol goes down, which might hurt heart health.
