eli5 Why do Potassium supplements only have 2% of the recommended daily value? (US)

570 views

In the US, potassium supplements are restricted to no more that 99 mg, or roughly 2% of the recommended daily value. Is there a point to such a low dosage? Is it okay to take more than 99 mg in supplement form?

A few years ago I called a vitamin company to ask about that. I was told ‘that’s all we can get in the pill,’ that the physical material required was very large. That, and they don’t try harder because it’s not meant to be a source but a supplement.’

I get horrible screaming foot cramps and if I religiously eat a banana a day it stays under control. So, in case I can’t get bananas I need other source. I keep avocados too but they’re not reliable either.
