Info about potassium supplementation products

My wife and I have a low potassium diet and need to supplement with 1.5g to 2.5g per day depending on how active we are and how much milk we drink for added protein.

We are getting a lot of contradictory info about potassium supplementation products.

We have been told by a PA and MD that that we are wasting our time taking OTC potassium gluconate because it is not being absorbed.

Online comments often repeat the same message. However the technical med literature I read says that 90% of both dietary and supplemental forms of potassium are absorbed by the intestines.

It also seems to make clear that the type of potassium salt you are taking (chloride, citrate, gluconate, acetate, bicarbonate, etc) does not matter. The only thing that counts is the amount of actual (elemental) potassium you are ingesting.

For instance we take 595mg tablets of potassium gluconate containing 99mg of elemental potassium. This means that if I am willing to take 20 of these cheap little pills a day to get my 2000mg (2g) of potassium that is just fine.

I don’t need to buy relatively expensive potassium chloride. Is this true?
