Why can't I find potassium supplements in dosages over 99mg per capsule?

Question

Bananas are around 400 mg, and I think the "suggested" daily dosage is twice that.

capsule or tablet, not powder.

Answer 1

Potassium Dosage
How much is usually taken?

The best way to obtain extra potassium is to eat several pieces of fruit per day, as well as liberal amounts of vegetables. The amount of potassium found in the diet ranges from about 2.5 grams to about 5.8 grams per day. The amount allowed in supplements-99 mg per tablet or capsule-is very low, considering that one banana can contain 500 mg. One should not attempt to achieve higher potassium levels by taking large numbers of potassium pills. This concentrated form of potassium can irritate the stomach-a problem not encountered with the potassium in food.

Answer 2

the FDA does not allow potassium containing supplements to be sold in dosage above 99mg.

The basic reason is that high concentrations of
potassium, such as might be present in a bigger rapid release pill, can
kill cells and cause tissue necrosis. Part of the intestine then gets
a hole in it, and that causes big problems. The prescription drugs are
rigorously formulated to be slow release, so that doesn't happen.

note that it is safe to get high levels of potassium in your food

Answer 4

Potassium is a dangerous "drug" for you to self dose. You can cause yourself to have a heart attack by taking too much. Check with a doctor to see if you need to use this as a supplement.

Answer 5

It's a scientific fact that if you put more than 99mg of potassium in a capsule it will explode! So they stop at 99mg and just make a bunch of them.
