> the max dosage you can get over the counter is 99mg Most people get enough potassium from their diet. It's easily available in larger quantities but safety is the main concern: http://www.straightdope.com/columns/read/1364/can-salt-substitute-kill-you/ http://www.straightdope.com/columns/read/1364/can-salt-subst...

But use with caution and usually with the advice of a physician.
