Micronutrients & recovery
Selenium status above 120 μg/L is associated with an elevated risk of type 2 diabetes and certain cancers.
Do not assume more selenium is always better. Levels above 120 μg/L in the blood are linked to higher risks of type 2 diabetes and some cancers. Avoid high-dose supplementation unless medically indicated and monitored.
ModerateRefutesMEDIUM confidence
Prospective studies provide some evidence that adequate Se status may reduce the risk of some cancers, while elevated risk of type 2 diabetes and some cancers occurs when the Se concentration exceeds 120 μg/L
Why this rating
Described as 'some evidence' from prospective studies.
