Diets based on fruits and vegetables serve as rich sources of alkaline potassium salts, but modern diets now consist of greater levels of acid precursors from disproportionately higher protein and cereal grain intake and disproportionately lower fruit and vegetable intake. The limited fruit and vegetable intake leads to a chronic, systemic state of low-grade metabolic acidosis that progressively worsens in the setting of age-related declines in renal function and consequent diminished renal acid-base regulation. This causes the release of alkaline salts from the mineral present in the skeleton, a homeostatic response that mitigates the degree of acidosis. [1]

Partially compensating for the acidogenic diet and resultant downward trajectory of systemic pH and to maintain systemic pH homeostasis, alkaline salts are liberated from the skeleton and are lost permanently in the urine, and therefore the bone density declines [1]. Acidosis may have unfavorable effects like weakened bones, kidney stone formation increases heart palpitation, etc. Potassium citrate is an alkaline potassium salt of citric acid that can help alkalize pH to make the body less acidic and mitigate the harmful effects of acidosis. Potassium citrate balances potassium levels. A normal level of potassium in the blood is important. Potassium helps your cells, kidneys, heart, muscles, and nerves work properly. Especially, potassium has been shown to support normal blood pressure levels thereby reducing the risk of a stroke.
