This inexpensive highly absorbent potassium supplement works very quickly to help low potassium symptoms (high BP, fatigue/weakness, restless leg while trying falling asleep, muscle aches/cramp/spasm/numbness/tingles, heart arrhythmia/palpitations, chest pain, digestive issues, high blood sugar, crankypantsness etc, etc.). Not having enough magnesium could also cause the problems since it affects the blood potassium level, along with certain metal toxicity (barium, thallium, cesium, etc) interferes with potassium absorption. Potassium citrate is a urinary alkalinizer with an added benefit of preventing kidney stones. Potassium is best taken in food forms (bananas, avocados, greens, beans, etc), but if you tend to overindulge in diuretics such as wine/beer/coffee, be sure to supplement with key minerals, such as magnesium, potassium, iodine, selenium, zinc, etc… On a related note, if you tend to abuse alcohol and/or insulin resistant, be sure to also look into the insidious and often undiagnosed Thiamine (B1) deficiency which greatly affects glucose metabolism and electrolytes exchange for your nerve and muscle cells
