Potassium chloride and its various formulations can be confusing—you may not even realize several different types exist until reading this today! When it comes to supplementing low potassium levels, there are a few oral options, but they are absorbed into your system in different ways. If one type is causing troublesome side effects for you, another version may work better.

Does it matter which type I receive? Is there a difference in their absorption?

Oral potassium can upset the stomach and possibly lead to stomach obstruction or lesions. Be aware that you may tolerate one form of potassium better than another, and you may need to try more than one to find the best option for you.

When it comes to the effectiveness of different types, there have been several studies conducted that compare microencapsulated potassium (capsules) with wax matrix potassium (tablets), and there were no clear differences noted.

So what forms are available?

Potassium is available in tablets, capsules, effervescent tablets, powder packets, and liquid.

Some examples of the various names that potassium can be found under include: K-Tab, Klor-Con, Klor-Con M, and Micro-K.

What are the differences between the various types of tablets and capsules?
