How Much Potassium Do You Need Each Day?

Potassium requirements vary by age, sex, life stage, and the dietary guidelines being used. The US National Institutes of Health Office of Dietary Supplements lists adult adequate intakes of approximately 3,400 mg per day for men and 2,600 mg per day for women, including pregnant women. The recommended amount for breastfeeding women is higher.

These figures are adequate intakes, not a universal target for every person. Different authorities may use different reference values. You also do not need to get all your potassium from vegetables. Other sources include beans, lentils, fruit, dairy products, nuts, seeds, and other whole foods.

The easiest approach is to spread potassium-rich foods across your meals rather than trying to obtain a large amount from one food.

Can You Eat Too Much Potassium?

For most healthy people, the kidneys regulate potassium levels by removing excess amounts through urine. However, too much potassium can be dangerous for people whose bodies cannot remove it effectively.

People with chronic kidney disease, certain other medical conditions, or those taking medications that raise potassium levels may need to limit some potassium sources. Examples of relevant medications include certain blood pressure medicines, such as ACE inhibitors and ARBs, and potassium-sparing diuretics.

If you have kidney disease or take medicines that can affect potassium, ask your healthcare professional how much potassium is appropriate for you. Do not make major dietary changes or start potassium supplements or potassium-based salt substitutes without appropriate medical guidance.

For people who need to monitor potassium, the amount in a particular serving and the overall daily intake matter more than whether a food is generally considered healthy.

The Bottom Line

Spinach, kale, potatoes, Brussels sprouts, artichokes, mushrooms, winter squash, beets, carrots, and broccoli can all contribute potassium to your diet while providing other important nutrients.

You do not have to eat every vegetable on this list or reach a specific amount from vegetables alone. Focus on eating a variety of vegetables, preparing them in ways you enjoy, and combining them with other nutritious foods.

If you have a medical condition that affects potassium regulation or take medication that can increase potassium levels, consult your healthcare professional before making substantial dietary changes.
