Yes, but only to some extent. We are all mammals. We'd be wise to account for the effects that chelators have in mammals while also being alert for the additional variations in effects.
Re IV Chelation. Think carefully about it. With IV you get a relatively big infusion of chelators for a relatively short time (relative to low, frequent dose (cutler) protocol for a long weekend or longer). I liken it to dusting your dining room table with a leaf blower. Yes it will remove dust, but you can bet it will leave more dust on your chandelier which is more difficult to clean. You won't notice much difference if the table isn't very dusty but if there is much dust, it will be obvious.
