My naturopath is extremely picky about brands and recommends only
Prime Chlorella. She says that Chlorella cultured in natural lakes/ponds is often full of heavy metals, no matter how pristine the lake - it's the chloralla that's keeping it pristine by absorbing all the toxins! This is grown in a controlled environment and uses 3rd party testing to ensure purity.
According to my naturopath, Chlorella does not actively detox, rather it only "mops up" toxins already present in the system. So it wouldn't be doing any chelating, just cleaning up what's already free-floatin' around, so to speak.
