> Potassium deficiency is very rare Potassium-deficient diets are not rare. Using the U.S. as an example, only 3% of people in the U.S. consume adequate levels of potassium in their diet according to the most recent NHANES survey.[1] The U.S. Dietary Guidelines Advisory Committee has identified potassium as 1 of 4 "shortfall nutrients" (nutrients that are underconsumed by the U.S. population at large) that are of public health concern in 2015.[2] That is why the FDA has required food manufacturers to include potassium amounts in the "Nutrition Facts" label since 2016.[3] [1] https://academic.oup.com/advances/article/4/3/368S/4591617 https://academic.oup.com/advances/article/4/3/368S/4591617 [2] https://nutritionj.biomedcentral.com/articles/10.1186/s12937-017-0230-0 https://nutritionj.biomedcentral.com/articles/10.1186/s12937...

Given that 68% of people in the US are deficient from the other electrolyte, magnesium, I maintain that potassium deficiency is rare(r), and certainly is scarier to supplement that Mg is. https://www.lifeextension.com/magazine/2005/9/americans-magnesium-deficient https://www.lifeextension.com/magazine/2005/9/americans-magn...

  What? 97% of U.S. people have potassium-deficient diets, which is greater than the 68% of U.S. people who have magnesium-deficient diets (according to your source). I agree that anyone who is taking potassium supplements should carefully monitor their potassium intake, but almost all foods have low enough levels of potassium that excessive potassium consumption is extremely rare. The FDA limits most potassium supplements in the U.S. to 99 mg per dose, an insignificant 2% of the Daily Value.* * https://ods.od.nih.gov/factsheets/Potassium-HealthProfessional/ https://ods.od.nih.gov/factsheets/Potassium-HealthProfession...
