Magnesium will help with constipation and will not block your guaifenesin, it’s not a plant and has no salicylates to worry about 🙂
BUT! If you take a ton of it to help with constipation and end up with the runs, there is no guarantee that the guaifenesin absorbed properly to do its job. Our advice is to take it about an hour before or after you take your guai.
This is the same rule for any fiber type supplements you take like psyllium husk or flax. (flax should only be taken in small amounts as it’s a plant and can block, psyllium husk is just the husk from the plant, so it won’t block) These fibrous types expand in your stomach, in an effort to pull along other stuff in there that isn’t moving along as it should. (to put it nicely LOL :D)
This expanding can surround your pill and keep it from digesting. SO, the same rule applies with these fibers and other GI meds- take an hour or so before or after your guaifenesin to be sure that the guai has a chance to absorb properly 🙂
Check out another post I did on Magnesium! Turns out Magnesium is really good for you! 🙂
