edit: also as far as magnesium threonate, jarrows and swanson are both good brands that are available on amazon but if you were looking for cost-effectiveness, you can get 1kg of magnesium taurate for <$40 which is like a year supply lol. it's magnesium bound to taurine, so it's a bit different than magnesium threonate but does essentially the same thing. i found the taruine in it would also help make coffee feel a bit smoother, but if i took it before bed i got the same effects as i would from magnesium oxide or magnesium citrate
