Best Potassium Supplements

When it comes to the best potassium supplements, the answer may not be so cut and dry. The reason being is that potassium is an essential mineral, but too much of it and the wrong kind of it can lead to some very serious side effects that you need to watch out for.

So in this article, we’ll be talking about the best potassium supplements on the market, but not before we discuss safety and other forms of getting potassium in your diet.

 

What is Potassium?

Potassium is a mineral and electrolyte. It’s involved in multiple important processes in the human body, including regulating the amount of water in the body, heart function, and muscle contractions. (1) (2)

Potassium is incredibly important, yet a large portion of the worldwide population doesn’t get enough of it in their diet. (3) (4)

 

Potassium Benefits

There are numerous health benefits that potassium has on our bodies.

 

Could Aid in The Prevention of Kidney Stones

Calcium buildup is one of the most common culprits of kidney stones and potassium has been shown to lower calcium levels in urine. (5) (6)

Large studies in both women and men have shown that there’s a correlation between higher potassium intake and a lower risk of kidney stones. (7) (8)

 

Could Help Prevent Osteoporosis

Some studies have shown that people who get more potassium in their diet have more dense and healthy bone mass. (9) (10)

 

Lowers Blood Pressure

In a meta-analysis of studies done on potassium’s effect on blood pressure, researchers found that people who had the highest potassium intake had lower blood pressure than the people who consumed very little potassium. (11)

 

May Provide Protection from Stroke

Multiple studies and meta-analyses on potassium and stroke have found that a higher intake of potassium is correlated with pretty significantly smaller risk of having a stroke. (12)(13)

 

Safety & When to Take a Potassium Supplement

The FDA has put certain restrictions in place for potassium supplements because of concerns over potassium overdosing. Namely, they’re concerned with the elderly, diabetics, people with heart conditions, and anyone who has any condition that affects kidney function because the kidneys regulate potassium levels in the blood. If you have any kidney function issues, taking potassium supplements could be dangerous, and the FDA doesn’t want supplements to pose a danger to anyone.

The recommended daily value for potassium intake is 4700 mg per day. But you won’t find near that amount in potassium supplements because the limit for manufacturers is doses of 100 mg.

That means that you have to get the majority of your potassium through foods rather than supplementation, which is a good idea anyway for any vitamin/mineral. Potassium supplements should really just be used when you absolutely need them.

Some potassium-rich foods that you can incorporate into your diet include:

  • Bananas
  • Avocados
  • Spinach
  • Beans
  • Potatoes
  • Sweet Potatoes
  • Pomegranate
  • Beets
  • Squash
  • Watermelon
  • Coconut Water

Considering the health concerns with potassium supplementation, the only instance in which you should do so is at the request of your doctor. With that said, in the following sections we’ll go over what we believe to be the best potassium supplements available on the market today.
