The Claim
In individuals following a vegan diet with low baseline selenium status, consumption of Brazil nut butter or selenium supplements results in a significant increase in selenoprotein P concentrations by approximately 1.4–1.9 mg/L over a two-week period, with a greater magnitude of increase observed in vegans compared to omnivores, demonstrating that selenoprotein P is a sensitive biomarker for selenium repletion in individuals with suboptimal selenium status.
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 vegans with low selenium levels, eating Brazil nut butter or taking selenium supplements raises selenoprotein P levels by 1.4–1.9 mg/L within two weeks, and this increase is larger in vegans than in people who eat meat.
See the scientific wording
In vegans with low baseline selenium status, both Brazil nut butter and selenium supplements significantly increase selenoprotein P (SELENOP) concentrations by approximately 1.4–1.9 mg/L over two weeks, with a more pronounced response in vegans than in omnivores, indicating that SELENOP is a sensitive biomarker for selenium repletion in individuals with suboptimal status.
When selenium levels are low, the body makes more of a protein called selenoprotein P to transport selenium to tissues. Eating selenium-rich foods or taking a selenium supplement raises selenium in the blood, which tells the liver to produce more of this transport protein. People who start with low selenium show a bigger increase because their system was running on empty, while people with enough selenium don’t respond as much because their system is already full.
What the research says
1 studyWhen vegans with low selenium levels ate Brazil nut butter or took a selenium pill for two weeks, their body’s selenium transport protein (SELENOP) went up a lot — more than in people who ate meat. This proves SELENOP is a good way to track if selenium levels are improving.
