why arent you supposed to have grapefruit if you take potassium? please be specific?

Answer 1

While grapefruit does have high levels of potassium in it, this is not why it shouldn't be eat while taking potassium supplements. Grapefruit and its juice inhibit the binding of many drugs with the Cytochrome P450 enzymes that they require to produce an effect. Grapefruit is highly reactive with several drugs and shouldn't ever be consumed while taking certain drugs. If the drug cannot bind the target enzyme, it will not produce the therapeutic effect that it is prescribed for. In fact, since the bioflavonoids and furanocoumarins bind the enzymes, the drugs are unbound in circulation and can cause an increased rate of absorption which could lead to toxic levels in the body. Grapefruit also weakly interacts with the uptake of ions (like Potassium and Sodium) by activating efflux pumps in the gastrointestinal tract.

Answer 8

Just a quick correction of the info. from the nursing student. She is confusing the chemical symbol for potassium (K) with Vitamin K. Potassium is a mineral and is NOT related to Vitamin K (phylloquinones).

Answer 10

Grapefruit has loads of Potassium, in and of itself. Potassium is also known as vitamin k. Vitamin K does two main things- it keeps the heart rate regular, and it controls the clotting of blood. Too much potassium/vitamin k will cause cardiac dysrhythmias (heart beat goes all funky) and hypercoagulation (blood clots VERY fast). A blood clot in the heart will eventually be dislodged by the force of the heart, and will travel to...
another part of the heart (heart attack),
the lungs (pulmonary embolism),
or the brain (stroke).

grapefruit, bananas, and many leafy greens have potassium/vit K, so be careful!
