I would like to add that all over-the-counter potassium is just 99 milligrams by law. This is why doctors tend to prescribe it for patients that need considerably more - so you don't have to take a lot of pills all day long. The doctors can also prescribe time-release potassium. However, as pointed out, prescriptions are expensive and often unnecessary when you can just buy the OTC version and take a few more pills. I have always found that time-release doesn't work very well anyway and spreading your potassium out throughout the day is the best way to take it to avoid gastric upset. Always take with food or a large glass of water unless instructed otherwise by your physician.

  My potassium levels were a little high so I now take only one 5mg of Potassium Citrate and 2 Magnesium Citrate tablets. I have had no stones since starting this regime. I wish they had just the citrate! Lemon juice is also a good source of citrate which is the magic ingredient against calcium deposits forming stones. Use dairy as a source of calcium---it does not form stones. Greens such as collards and mustards, calcium based antacids and calcium supplements can accumulate as kidney stones. if this has been a problem---make sure you know that calcium is the composition of your stones.

  Your physician is unlikely to have prescribed such a tiny amount as 5 mg of this mineral. More likely, it was 5 mEq of potassium. To get the equivalent in milligrams you will need to know exactly which potassium your doctor recommends as each potassium has a different molecular weight and to convert mEq to milligrams you need to know the weight. The internet tells me that 5 mEq's of potassium citrate =540 milligrams of potassium citrate. But if your doctor indicated potassium chloride then 5 mEq = 320 milligrams. I hope this helps.

  I am have a recurring kidney stone problem, so I can appreciate the question.
I have not found that this has increased my formation of stones.
The potassium Citrate I bought and pictured here is
99mg, so it would be more than the 5mg prescribed by
this person's doctor.
I am taking this, along with cranberry juice, daily,
and I have had no stone problems for the past 16 years, which for me, is almost a miracle

  I am not finding information on the website to explain what a capsule is. That would help.

Their capsules are actually clear tubes with powdered potassium citrate in it. You can open the tubes and pour out the powder, so this might work for what you have in mind. You could pour out half of the powder or any amount that you want. You could use the other end of the tube to pour an equal amount in both ends and get exactly half.

I very much like their vitamins.

Feel free to send more questions.

  It's a capsule. The powder inside can be emptied out, but it should NOT be divided in half. If you do so, you cannot be sure that you are truly getting half the dose, as the potassium may not be evenly distributed within the powder. If you need to take half this amount of potassium, look for a lower dose capsule or tablet.

  It appears that the 'plastic' outer coating can be twisted apart. Assuming the contents remain in a dry condition, I can only assume the contents could be separated in half. I didn't try it but would be happy to try one of the pills if requested.

  Don't know, but probably contains a powder. it probably can be taken every other day, and will have the same effect as one half per day.

  Capsules can neither be crushed nor cut in half; they can be opened and the contents sprinkled.

  This item is not listed as non-gmo.

  This product is a mineral. It does not have genetic material nor is it sourced from an organism with genetic material.
