The Claim
Consuming two Brazil nuts per day results in selenium bioavailability equivalent to that of a 100-microgram selenomethionine supplement.
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.
Eating two Brazil nuts daily delivers the same amount of usable selenium as taking a 100-microgram selenomethionine supplement.
See the scientific wording
Two Brazil nuts per day provide selenium bioavailability equivalent to a 100-microgram selenomethionine supplement.
When you eat Brazil nuts, the selenium inside them gets absorbed in your gut, converted into a usable form, and used to build special proteins that protect your cells from damage. These proteins also carry selenium to other parts of your body. The same process happens when you take a selenium supplement, so both sources end up doing the same job in your body.
What the research says
2 studiesEating two Brazil nuts a day gave people the same boost in selenium levels as taking a selenium pill — meaning the nuts work just as well as the supplement.
Study: Brazil nuts: an effective way to improve selenium status.
Eating two Brazil nuts every day raised selenium levels in the body just as much as taking a selenium pill — and in some ways, even better. So yes, nuts can be a natural alternative to supplements.
