Is pure potassium dangerous?

Kaboom! Pure potassium is a highly reactive metal. Exposed to water, it explodes with a purple flame, so it’s usually stored under mineral oil for safety. Because it’s so reactive, potassium isn’t found free in nature, according to the Jefferson National Linear Accelerator Laboratory.

What are the benefits of potassium?

Potassium is one of the most important minerals in the body. It helps regulate fluid balance, muscle contractions and nerve signals. What’s more, a high-potassium diet may help reduce blood pressure and water retention, protect against stroke and prevent osteoporosis and kidney stones.
