When testing just becomes more noise.

Anyone who listens to Andrew Huberman - which admittedly I do from time to time, as he is great at communicating science to the masses - has sat through the sponsored bit where blood tests for heavy metals are framed as a detox compass. To be frank: This sponsored bit is pretty impressive confidence for inaccurate science. And it hurts my soul.

As someone who routinely screens and treats clients for environmental toxins for over a decade, this is just not right.

Blood heavy metals reflect what you ate yesterday. Sushi today, panic tomorrow - according to blood test. Skip fish for a few days, miracle recovery - also according to blood test. That’s simply temporary exposure and has nothing to do with toxic body burden.
