5 Best Potassium Supplements for Keto Diet [Buyer’s Guide]

In a hurry? The best potassium supplement is Solaray potassium supplement.

Being on a keto diet plan will deplete electrolytes in the body quite quickly. 

Electrolyte imbalance is common side-effect but don't worry there's a simple solution.

A lack of proper electrolytes balance can cause other side effects such as muscle cramps, lack of energy, and poor sleep patterns.

Potassium is an essential mineral that the body needs to ensure proper function at a cellular level. It is one of the significant “electrolytes” in the body, and when dissolved in water, it produces positively charged ions.

For regular dieters banana is the way to go to for potassium. It is delicious, full of potassium but also high in carbs, so it's a no-no when it comes to keto.

Luckily, there are better alternatives for ketoers (supplements & veggies) that fill this gap perfectly.

Why There’s
Potassium Deficiency?

Potassium helps regulate muscle contractions, maintain healthy nerve function and regulate fluid balance in the body. It is an essential mineral that the body requires for the proper functioning of its muscle cells, liver and bones.

Potassium deficiency, otherwise called hypokalemia, occurs when your body unexpectedly loses a lot of fluid. Common causes are chronic vomiting, excessive sweating, diarrhea, and blood loss. It is characterized by a blood potassium level below 3.5 mmol per liter. (1)

The recommended daily potassium intake is 4,700 mg. Being on a keto diet plan has its perks, however, it often results in potassium deficiency. This is because a keto diet flushes potassium out of your system at a faster than the usual rate and as this is processed through the kidneys it can affect the electrolyte balance. (1)

Because the kidneys control the levels, drop-in potassium can also be experienced. Therefore, you need to be particularly strict with maintaining optimal intake of potassium during keto. In the event that you do not replenish these electrolytes as soon as possible, you risk experiencing some nasty deficiency symptoms. (2)

Some symptoms of potassium deficiency you can experience on a keto diet plan include fatigue, muscle weakness, muscle cramps, constipation, heart palpitations, tingling, numbness, and itching in your extremities. (2)

Can You Get
Potassium From Food?

Absolutely! Since the body can’t make potassium on its own, it’s your job to eat the right foods to give it the potassium it needs. Many fruits and vegetables are rich in potassium but potassium supplements are small and easy to take compared to foods.

Supplements, however, isn’t for everyone, it is only recommended for specific people. For instance, you need to eat a lot of specific foods (you may not like these potassium-rich foods) if you don’t want to take supplements. Also, you can get more needed minerals through quality supplements. (18)

Potassium can be derived from several foods but only a handful of these potassium-rich foods can be taken on a keto diet. They include:

How Much Potassium
Do You Need?

Getting enough potassium is essential for healthy bones and heart. There isn’t an RDI for potassium. However, organizations around the world have recommended consuming at least 3,500 mg per day through food. (23)

A healthy adult should aim to take 3,500–4,700 mg of potassium daily from foods. Getting a daily dose can be difficult. Most adults do not meet this recommendation and women consume less potassium than men on average. (23)
