> I don't know the fatal oral dose Probably the reason most OTC potassium supplements (ones sold in the US at least) have FAR less potassium in a single tablet than a banana. It's basically impossible for a adult with healthy function to overdose themselves on potassium with bananas (or coconut water, or avocados) before getting full, but with the tablets it would be much easier to abuse them if they contained even 1 banana's worth per tablet.
