Episode notes
Why Plant Proteins Show More Heavy Metals
- Plant-based protein powders tend to contain higher heavy metal levels because plants absorb metals from soil.
- Animal-derived whey undergoes biological and processing steps that reduce metal transfer into the final product.
Strict Limits Can Inflate Perceived Risk
- California's Proposition 65 uses extremely conservative safety factors that can make trace exposures appear unsafe.
- More typical agency limits (FDA, EFSA) are much higher and often imply no realistic health risk from observed supplement levels.
Balance Between Zero Risk And Practical Safety
- Absolute-zero risk targets are unrealistic and costly, so regulators apply pragmatic safety margins.
- Using more balanced thresholds shows the supplement levels found likely don't pose real health hazards.
