Potassium supplements are near hilariously trivial for potassium. That 99mg is, what, 2-3% of what a _non_keto user needs?
If you can find some Lo Salt or NoSalt or whatever āsalt alternativeā stuff in a store, pick that up. While we need extra sodium on keto too, this stuff happens to be potassium salt usually, and gives several hundred mg of potassium per serving.
ReHydr8 suppliments are decent for getting a range of electrolytes, but youāll want to take multiple of those a day, and the potassium content still isnāt very high.
Also notable: Pink salt has less sodium per serving than many other salts, and while many hype the fact that there are other minerals/salts in it, I havenāt found anything to indicate how much yet, and only indications that itās mostly negligible amounts of the other salts anyway. I use a bunch of pink salt around here because it, strangely enough, happens to have been cheaper when I bought a bunch of it than most the other salts, but I need to keep in mind I need to use extra too.
Interesting thing with the coffee I found the other day, most of the most highly concentrated sources of magnesium are in coffee and tea āpowdersā. I donāt drink coffee at all myself, and donāt now how well that transfers to a cup which is mostly water, but itās something to think about if you recently cut back on the coffee too.
