Drug distribution refers to the movement of a drug to and from the blood and various tissues of the body (for example, fat, muscle, and brain tissue) and the relative proportions of drug in the tissues. After a drug is absorbed into the bloodstream (see Drug Absorption), it rapidly circulates through the body.
The estimated minimum potassium requirements for women and men are 2000 mg per day. As children get older, they need more potassium and this increase can go up to 3800 â 4800 mg per day. A deficiency may cause muscular cramps, twitching, irregular heartbeat, kidney and lung failure and insomnia too.Daily potassium requirements: Potassium helps to maintain a healthy fluid balance in our body.s children get older, they need more potassium and this increase can go up to 3800 â 4800 mg per day.

A RealAge answered. We currently recommend getting at least 3,000 milligrams (mg) of potassium per day from food, but we're reviewing the latest science and expect our recommendation to increase -- so watch this space! The government now advises 4,700 mg per day. That said, don't take a potassium supplement unless directed by your physician, because too much of this mineral can be toxic. Some multivitamins contain potassium, but only in small amounts, so if yours is one of them, don't panic -- just make sure it's less than 100 mg.
