I'm going to take a potassium supplement. what's the best max dosage so i don't kill myself. a banana makes me have less muscle pain but oral allergy ?

Low potassium?: I have a question for you. Do you need to take a potassium (K) supplement? If you do not have a low blood K level, you do not need one. If you do, check you magnesium (M) level. Patients with low M levels will not be able to increase their K level until the M is repleted. If your M is low, eat foods rich in M, such as cashews, or try some M supplements. Check your M & K levels before adding K.

Other foods avail: An oral supplement should be prescibed and monitored by a doctor, after a true need has been determined. There are other potassium rich foods. A list of these foods is provided in this Mayo Clinic article. http://www.mayoclinic.org/drugs-supplements/potassium-supplement-oral-route-parenteral-route/description/drg-20070753 I'm happy to have helped.
