which is best? how much magnesium elemental in sulfate form? and what's the bioavailbility of sulfate, citrate has this information but not sulfate.
is it better for brain effects? sulfate rise magnesium in brain by 15%, how much for citrate?

because they're the cheapest, sulfate is the cheapest of all if i could save some bucks on it, i'm trying high doses so i need to buy bulk powder.Why are you restricting to just these two? There are much better forms of magnesium in terms of bioavailability and benefit - glycinate, malate, taurate, etc. Different forms may have different preferential targets in the body.

citrate doesn't give me laxative effects, so sulfate is branded as a laxative? that's kinda dangerous i don't want to stop my bowels from working.Sulphate isn't very popular as an oral dose form. I'm not sure why, but I'd guess it's too much of a laxative. Citrate has the same problem in some people. Like norepinephrine said, there are a lot of other forms, some of which may have advantages. Contrary to popular internet opinion, there isn't a huge difference between them as far as correcting deficiency. Even the much-maligned oxide, which is also very cheap, is pretty good. There was a paper published some while back claiming that its bioavailability was only 4%, but that was in error. Some of the counterions, like orotate, are large and heavy, so you need to take a huge dose of the compound in order to get the RDA of elemental magnesium.
I'd be careful with high doses, depending on how high you're talking about. There's such a thing as too much magnesium, and you could hurt yourself if you take too much. What are you taking it for?
how much magnesium elemental in this? if 2 gives 200mg then i would need 7 to 10 a day it would be too costful.FWIW, I got a 4 month supply of glycinate on Amazon for around $15 dollars. Say you take 2 a day - cost per dosage is 12.5 cents.

magnesium oxide i had a huge bottle of it from twinlabs, i'm not even sure it did anything, it had a laxative effects but pretty innefective for my issues.
i read about that 4%, so finally does it get to the brain like citrate and sulfate? i'm trying high dose to correct anxiety and have better brain function, i read a paper saying magtein is a fraud and sulfate raises brain magnesium by 15% like magtein.
do you know elemental magnesium per mg of magnesium orotate? i can't find this anywhere, they just list the content of magnesium orotate.
i'm taking between 750-1000mg elemental in powder, half in the morning, half in the evening. what do i risk?

Hypocitraturia, a low amount of citrate in the urine, is an important risk factor for kidney stone formation. Citrate in the urine has long been recognized as an inhibitor of calcium salt crystallization. Citrate is the dissociated anion of citric acid, a weak acid that is ingested in the diet and produced endogenously in the tricarboxylic acid cycle. The mean urinary citrate excretion is 640 mg/d in healthy individuals.
