Hard to tell, the only time I see visible (and feel it) is after I rife but that doesn't mean the enzymes and DMSA aren't working.
That said; I would think DMPS would work better which is most likely why I reacted so well to it and of course Chlorella seems to help along with my ISO Whey + Konjacu shake.
NOTE: ISO Whey is well known to interact with gut heavy metals, which is most likly why I needed to add the konjacu to it...
