I use an ionized liquid from mag-i-cal.com because it is cellular ready and therefore is 100% bioavailable. I take 400mg at night (this is when your levels are the lowest) and 400mg in the mornings (2nd lowest time) and then I will take more if I see my levels dropping (waking up at night, muscle tension are my two symptoms that appear first, and also irritablitiy).

I believe Cuttler recommends 600-800mg. Also keep in mind that you absorb more from liquid, then capsules and lastly tablets. This is especially important if you have compromised
digestion.

There are many forms out there and it can be very confusing and difficult trying to find one that is good for mercury toxic people. You also will need more than the average person because hg blocks mg and you also use so much while detoxing.

Don't worry about too much. Your body will flush out excess (if a hg toxic person could actually get too much!)

Most mg is bound to an amino acid to make it more absorbable. Mg oxide-cheap, but no good
Mg aspartate or glutamate-stay away from these because they are excitatory amino acids.

Mg citrate-many people like this one if they have tendencies toward constipation as it draws water into the colon. Some use a little of this along with another form. There is a powder of citrate called Natural calm that you mix with water.

Mg taurine, malate are also good forms.
