Potassium: Why you need it, and where to get it


Potassium is an essential mineral and electrolyte that's well known to reduce blood pressure.


Because high blood pressure significantly raises the risk for kidney disease and cardiovascular disease such as stroke, coronary heart disease and heart failure, adequate intakes of potassium are associated with their reduced occurrence.


Research also points to potassium's supportive role in bone mineral density, blood sugar control, insulin sensitivity and reducing the risk for type 2 diabetes. The electrolyte is involved with proper muscle contraction and nerve function.


How Much Potassium Do You Need?

The National Institute of Health (NIH) recommends:

  • 2,800mg/day for non-pregnant/lactating women 19 years and older

  • 2,800-2,900mg/day for women 19 years and older who are pregnant or lactating

  • 3,400mg/day for men 19 years and older

American women and men are not meeting those recommendations though, and instead are consuming on average about 2,600mg/day.


Consequences of Insufficient Potassium Intake

Low potassium intake can cause sodium retention and efflux of calcium from bone. Over time, these circumstances increase the risk for development of high blood pressure, insulin resistance, osteopenia and osteoporosis, and kidney stones.

Fruits, vegetables, and animal proteins including dairy milk and yogurt are among the best natural sources of potassium.
