Potassium supplements: why so far below the RDA?

I've noticed that potassium supplements, either potassium gluconate or citrate, only deliver 3% and 10% of the RDA of potassium respectively per dose. The directions on the bottles also suggest only 1 and 1-3 doses per day. Why are these values so low, given that many vitamin supplements deliver 100% of the RDA or more?

Most people are sporadic with how much potassium they get during a day and too much potassium can be fatal. It's low so manufacturers don't have lawsuits on their hands.
