Recently started to take magnesium supplements, after some Googling and finding an old HN post about experiences around it, going for glyciate rather than oxide (latter was the only one I could find at pharmacies).

In 1 week I've yet to experience any of the positive effects often listed (maybe slightly better sleep?) bar one surprise: I don't wake up for bathroom visit anymore.

Used to wake up once a night for toilet visit, but that disappeared. Anyone have had similar experience? My (old) father have been complaining about 2-4 toilet visit per night and was wondering if I should suggest magnesium supplement to him, or if this is just placebo.

I've read that too much magnesium hinder Zinc uptake, so I assume blindly suggesting it to others might have adverse effects depending on lifestyle

1. Sleeping through the night, regardless of how you feel otherwise, is a great benefit. 2. Salt is anti-diuretic, so I'd suspect the effect is real, but not specific to magnesium. And like any supplement, it works for you because you presumably weren't already getting enough in your diet, so.. ymmv.

If you are peeing overnight on the regular, get your blood sugar and A1c checked to make sure you don't have diabetes.

Waking up for bathroom affects sleep quality which, in turn, can lead to many other issues. Stop drinking water 4h (not 2h) before going to bed.

Oh definitely. Well the problem with not drinking water before bed is that, then I wake up due to thirst. Which was originally why I started drinking more water (I still chronically drink too little water every day) and then caused waking up for toilet visit.

If you're waking up thirsty then that might be a symptom that you're mouth breathing at night. Have you tried video recording yourself at night to check?

That's an interesting point! Nope haven't recorded myself, I rarely wake up being dry in my mouth, if that's an indication, nor do I snore a lot or have the tendency to mouth breathe.

I would think (?) I would notice if I mouth breathe excessively, sine I hurt my throat while sleeping when I catched covid, and then I could only mouth breathe for several days due tapped nose. Noticeable difference

But recording / asking SO to check could be a good thing. Thanks for the suggestion!

How do you not feel thirsty?

I found it had the opposite effect taking before bed.

What amount is your daily dosage?

As per suggestion, 105mg (25% DRI) recommend on the label. I've noticed some stomach ache now and then so I'm not sure if I'd like to take more than that
