Potassium is the third most abundant mineral in the body so it is no surprise that a potassium deficient diet can lead to a slew of problems. The most common symptoms of potassium deficiency include fatigue, muscle weakness, and brain fog. In addition, supplementing potassium has been proven to stimulate neural activities like memorization and learning, help lower blood pressure, and reduce stress and anxiety. Potassium plays a vital role in maintaining water balance in the body, and a sufficient concentration is also required for regular contraction and relaxation of muscles.To an extent, a state of potassium deficiency can be thought of as being intoxicated by alcohol - where both are characterized with poor muscle coordination, lapses in judgement, and potentially even poor memory. The daily recommended value is 4700mg - 12 bananas worth - of potassium, and I’m willing to bet that you’re not getting enough of it on a consistent basis.
