The Claim
Administration of selenomethionine for 5 months does not increase total selenium retention in plasma or cellular compartments, despite measurable redistribution among plasma proteins, in chronically selenium-deficient populations.
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.
Taking selenomethionine for five months does not increase the total amount of selenium retained in the blood or cells, even though selenium shifts between different blood proteins.
See the scientific wording
The form of selenium administered (selenomethionine) and the duration of supplementation (5 months) do not result in increased total selenium retention in plasma or cellular compartments, despite measurable redistribution among plasma proteins, indicating that supplementation may not effectively restore selenium status in chronically deficient populations.
When selenium is given as selenomethionine, the body first uses it to make essential selenium-containing proteins, but once those are fully made, extra selenium gets stuck to common blood proteins that don't need it. This moves selenium around in the blood but doesn't increase the total amount stored in the body, so deficiency isn't fixed.
What the research says
1 studyEven after five months of taking selenium supplements, the body didn’t store more selenium overall — it just moved it from one blood protein to another, like rearranging furniture without adding new stuff. So the supplements didn’t fix the long-term deficiency.
