>not recommended because it's not very effective

My guess is that it's effective for those that are chronically K deficient, through Hyperaldosteronism or some other condition.

That would still be four large potatoes a day, to hit the original RDA. Every day.

I buy it in powder form to get the high levels needed. https://www.bulksupplements.com/products/potassium-citrate-p...

Agree, the dosing on tablets are ridiculously low.

Eating several large potatoes, bananas, avocados every single day sounds miserable.

Beans are not recommended if your goal is normalising electrolytes and micro-nutrients. Phytic acid in beans messes with your micronutrient absorption, in other words you absorb fewer than if you abstained from beans (or any other vegetable high in phytates). Quite counterproductive if you're trying to figure out the correct dosage of supplements.

Same with nuts and other seeds. Fine, in moderation. Phytic acid literally is a chemical countermeasure to stop animals from eating the next generation of a plant.

Oxalic acid, abundant in spinach, is another fun one.

Soaking the beans and discarding that water before cooking them greatly reduces the phytic acid. Beans are excellent for health. You just have to follow the traditional methods of prepping them.

Look out for kidney stones with spinach, and other foods that are high in oxalates.

I've had multiple lithotripsy procedures, thanks to kidney stones.

I wouldn't wish kidney stones on my worst enemy.
