I am chronically low on potassium.
I take a 2% DV supplement twice a day, eat bananas, broccoli and avocadoes, just to stay ‘within range’.............
You might try the no-salt type of salts just to see if it is acceptable to you. 2% DV is roughly 50 mg dose. Switching to no-salt is not going to significantly add to that but may be an added boost.
You may be low in other minerals as well. I take Bariatric Advantage Advanced Multi EA vitamins, 1 per day, as my regular multi vitamin. You can get them from Amazon, about $45 for 60 count. If I do not take them, after a couple of days I will get leg cramps when I sleep.
