The Claim
In adults consuming a low-selenium diet, daily supplementation with 30 μg of selenium as selenomethionine for five months reduces the retention of a tracer dose of stable selenium-74 in plasma proteins compared to placebo, indicating altered selenium metabolism without evidence of repletion of critical selenium pools.
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.
Adults eating a diet low in selenium who take 30 micrograms of selenium as selenomethionine daily for five months show lower retention of a stable selenium tracer in plasma proteins than those taking a placebo, indicating a change in selenium metabolism without restoring critical selenium stores.

In adults consuming a low-selenium diet, daily supplementation with 30 μg of selenium as selenomethionine for five months reduces the retention of a tracer dose of stable selenium-74 in plasma proteins compared to placebo, indicating altered selenium metabolism without evidence of repletion of critical selenium pools.
When selenium intake increases, the body first fills its most important selenium-dependent proteins. Once those are full, extra selenium binds to less specific proteins in the blood, and the system clears the excess faster, so less of the tracer stays in the bloodstream.
What the research says
1 studyWhen people with low selenium eat a daily selenium supplement for five months, their bodies don’t store more selenium in important places like red blood cells — instead, they just move it around in the blood, showing the supplement isn’t fixing their selenium deficiency.
