There are a lot of opinions about this, but the consensus seems to be that the cheapest supplements, which are typically just magnesium oxide (the stuff that lifeguards put on their nose), are the least absorbable. Some sources say that Mg Chloride is preferable, and that's what's in Slo-Mag, which is readily available. So I've been using that, in conjunction with Bluebonnet Albion Mg glycinate.
