You probably didn’t take enough to meet even a fraction of your RDA, let alone enough to move the needle.
Potassium’s therapeutic window (the difference between effective dose and lethal dose) is relatively small. The FDA limits OTC potassium supplements to 99 mg per dose due to safety concerns like hyperkalemia. You'd need to take about 48 pills to meet the recommended daily amount of 4,700 mg, making it impractical compared to getting potassium from food.
The most widely available concentrated source of food grade potassium is potassium hydrogen tartrate, better known as cream of tartar, widely used in baking and cooking [1]. It's about 21% potassium by mass, available in practically any grocery store, and inexpensive in bulk. So it's a great alternative to potassium supplement pills, at least for people who can do arithmetic.
If people cannot do arithmetic, they may induce hyperkalemia:
Journal of Medical Toxicology, 2013: "Life-threatening hyperkalemia from cream of tartar ingestion"
Case reports: In both cases, individuals ingested a large quantity of cream of tartar in an effort to "clean themselves out". They manifested similar initial symptoms (vomiting), abnormal serum potassium (>8.0 mmol/L), and EKG's with peaked T waves. Both patients were treated for hyperkalemia and recovered without complication.
You are wrong. I am aware of the FDA limit on pills. That's why I used potassium chloride powder instead. I don't remember the exact amount, maybe half the RDA?

N=1 I tried taking potassium supplements and didn't see any noticeable effect on my blood pressure, unfortunately.
