Functioning of the acid-base-balance

A suitable acid-base balance is necessary for the normal action of the metabolic processes. If acids and bases are in imbalance, this can lead to changes in the specific pH values and the body has to invest energy in order to restore the acid-base balance. The more distinct the disturbance of the acid-base balance, the sooner the narrow range of the physiological pH value is exceeded and the system can derail.

The acid-base balance in our body should not be seen as a rigid system but rather as a continuously moving dynamic equilibrium. The main task is to maintain pH values, which should be as stable as possible. Indeed, the quantity of acids and bases in our body changes permanently and, yet, the pH value in the various organs and tissues and that in the blood stay constant within a narrow range.

The physiological pH-value

Each organ or each stage of the metabolism has its own optimal pH value.

  • Blood plasm pH 7.35 – 7.45
  • Gastric juice pH 1.2 - 3
  • Bile pH 7.4-7.7
  • Urine pH 5-8
  • Saliva pH 6.8
  • Joint fluid pH 7.4-7.8
