week 14 post-op, i wasn’t sleeping through the night. restless legs were brutal, and the pain would spike if i’d been tense all day. started messing with higher dose mag - went from like 150mg to 400mg glycinate in a single dose before bed. sleep improved noticeably. tracked it in my recovery notes alongside PT metrics, and within two weeks my ROM gains were steadier because i wasn’t waking up tense. chelated form beats the cheap stuff - absorption matters when you’re loading higher. i settled on around 500mg/day split dose. wasn’t cheap, but the sleep delta was real. not a fix on its own. but if you’re recovering from something and sleep is getting wrecked by restlessness, might be worth a protocol run.
The “sleep delta was real” framing is actually the more interesting claim here, and the mechanism is plausible: magnesium acts as a natural NMDA antagonist and helps regulate cortisol timing, which is probably why the effect shows up at the sleep-pain interface specifically rather than as direct analgesia. A study I read on mag glycinate in post-surgical populations found the benefit concentrated in sleep architecture metrics more than VAS pain scores, which tracks with what you’re describing. The absorption point matters too because oxide bioavailability is genuinely poor, somewhere around 4% versus 50-80% for glycinate or threonate forms, so comparing “I tried mag and it didn’t work” across forms is almost apples and oranges. One thing worth flagging for anyone reading: 500mg/day is above the tolerable upper intake level from supplements alone (350mg from supplemental sources per most guidelines), so worth discussing with your GP, especially post-op when you’re already on other things.
the bioavailability split you’re citing is spot on - oxide at 4% is why so many people say mag doesn’t work for them. on the upper limit flag, that 350mg is the conservative recommendation for baseline supplementation, not post-op populations under clinical care. i cleared it with my surgeon before bumping to 500mg given the NSAIDs i was already on. fair point to flag it though - people should check with their team instead of just copying the protocol.
The “cleared it with my surgeon” point is fair, and that’s exactly the right move. Where I’d push back a little: NSAIDs + higher-dose mag isn’t consequence-free in post-op contexts, specifically because both can affect gut motility and absorption unpredictably, so the 500mg that works smoothly for you might behave differently for someone on a different NSAID regimen or with compromised GI function post-surgery. The surgeon sign-off matters, but the specific combination still warrants individual monitoring.
