I wouldn't read too much into the title, the closing parts of the article give a much more balanced take on the whole issue. This study disagrees with some previous work and it's unclear which result makes sense and why. As usual, more research is needed, and while a catchy title is nice, this isn't anything to change your dietary habits by,

I know this isn't related to potassium directly, but anecdotally I have had success using magnesium supplements for insomnia/improving general sleep quality. I have also been consuming electrolyte mixes containing potassium to help with muscle recovery from training, and have found them to help with physical soreness & general well-being.

    What form of magnesium? It might mean something.

    Mg also acts on GABAergic/genic systems directly, but its benefits as a general supplement on sleep are disputed.

    • vixen99 an hour ago

      Depends what you mean by 'general supplement' but a majority of people are deficient in magnesium (~400 mg/d is the recommendation) and its ubiquitous involvement in hundreds of enzyme systems might reasonably indicate that a positive role in normal sleep patterns could be expected as reported in a number of publications. If there is no benefit then other factors are likely to be to the fore.

    My wife convinced me to take a bath with magnesium once when I was stressed.

    Afterwards I got up, went to bed, and slept like an absolute rock.

    • cbg0 2 hours ago

      If you took a bath in hot water, that has its own effects on the body, as it will lower your blood pressure, it can also relax your muscles, so you need to try it out without the magnesium to see if it did anything.

Strangely the original study misstates the direction of the main finding, contradicting itself directly.

Is this a typo, or something more nefarious?

From the abstract:

    Multiple regression analyses revealed that individuals with higher AIS scores had higher daily potassium intake

From the body of the paper (supported by the results):

    Multiple regression analysis indicated that individuals with a higher potassium intake had lower AIS scores.
  • OutOfHere 8 hours ago

    That is true. From section 2.6 of the full-text:

    > The sleep disturbances were assessed using the Athens Insomnia Scale [ 19], a self-administered psychometric questionnaire designed to evaluate sleep disorders, particularly insomnia [ 20 ]. It consists of eight items rated on a Likert scale ranging from 0 “no problem at all” to 3 “very severe” [ 20]. The total score ranges from 0 (absence of any sleep-related problems) to 24 (the most severe degree of insomnia). Severity is classified as normal for scores of 3 or less, subclinical insomnia for scores of greater than 3 but less than 6, and clinical insomnia for scores of 6 or more [19,21,22].

      The contradiction is more clear when comparing the abstract:

      > [...] Results: Multiple regression analyses revealed that individuals with higher AIS scores had higher daily potassium intake; potassium at dinner was especially crucial. [...]

      and section 3.2:

      > 3.2. Association Between AIS Score and Dietary Patterns of Sodium and Potassium > Multiple regression analysis was conducted to investigate the association between AIS scores and dietary patterns of sodium and potassium intake (Table 3). Total daily potassium intake was inversely associated with log AIS score (β = −0.036; p = 0.034). When intake at each meal (breakfast, lunch, dinner, and snacks) was analyzed separately, only potassium intake at dinner remained significantly associated with AIS score (β = −0.066; p = 0.003), suggesting that higher potassium intake at dinner may be linked to fewer sleep disturbances. No significant associations were observed for the sodium-to-potassium ratio.

            If it helps you sleep, a banana isn’t going to kill you. If it doesn’t help you sleep, then don’t eat a banana, that’s also okay.

      Two bananas to a potato (I assume we’re talking something like a russet, not a little red potato?) sounds generous to the potato, if we’re talking volume equivalence.

      A potato’s a meal. A banana’s a lightish snack.

        Per 100g ground beef is 300+mg of potassium

        No carbs, no sugars, no fiber induced bloating, could easily get more than 100g into a meal

        Potassium is a chemical element, frying it won't change the potassium level.

        • hilux 34 minutes ago

          I guess that depends how hot you fry it.

        • serf 4 hours ago

          you can most definitely change the levels of components in a fried food.

          the oil gets 'dirty' from extended use in frying. Why is it dirty? It's not dirt, and it's not oil breakdown (in most cases).

          The oil is drawing components from the food into itself.

          Forget the frying for a second; most fries are parboiled or blanched -- this also leeches material away from the vegetable, this time it leaves with the water used for blanching.

          A french fry is delicious, but it's different than a potato -- even if it's made from one.

      The original website is a news report of an article. The one he posted is from a peer-reviewed journal which has a much higher standard of reporting.

The real shocking information I gained from this paper is that the AIS goes from 0-24 (0 = perfect sleep, 24 = total insomnia) and the study participants had an amazing average AIS score of 4.3 (SD 3.3)! Wow, how well all those people must sleep!

As someone scoring 12, it's pretty bad and I am suffering a lot while trying to sleep and during day time because I did not sleep well.

If my understanding of statistics, standard deviations and the standardized partial regression coefficient are correct, potassium supplementation in the evening only DECREASES this score by about 0.2178 (Beta −0.066, multiplied with SD of 3.3), which is kinda worthless.

Please correct me if I am wrong.

  • OutOfHere an hour ago

    It decreases the score. It doesn't increase the score. An increase would be harmful. The beta is negative. The abstract is wrong.

    It is not worthless. For good sleep, potassium levels have to be adequate. Once one improves the level, one can move on to other factors.

    As for what works for me, avoiding caffeine after 12 pm helps, as does sunlight exposure in the daytime.

    With regard to a supplement stack, these help: collagen hydrolysate 12g, magnesium citrate, calcium, B6 as P5P, melatonin 4 mg, L-theanine 100-200 mg, and various sleep promoting herbs.

    Ensure your BP is optimal, well below 120/80 for most people under 70.

    Uncorrected acid reflux too worsens sleep, but avoiding consumption in the last three hours and also famotidine help.

    • Traubenfuchs 16 minutes ago

      > It decreases the score.

      Yes DECREASE instead of INCREASE. What I was going for in my head was "improve" I guess. Thanks for pointing that out.

      > B6 as P5P

      Don't forget it's one of the few nutrients that accumulates and that you can get too much of. It causes nerve damage and mystery sores.

      > melatonin 4 mg

      That's probably too much:

IIUC, Na is used like signaling medium in body and alkaline metals that isn't Na tends to reduce blood pressure, slow heartbeat and neural activity. With that in mind, it sounds reasonable that those tendency could lead to slightly deeper sleep. Or is there something else to it?
