A healthy result should fall into the range 0 - 100 umol/L.

Citric acid, cis-aconitic acid, and isocitric acid are the first three metabolites in the Krebs Citric Acid energy production cycle, which operates in the mitochondria of your cells. 

Citrate, cis-Aconitate (and Isocitrate) are involved in both energy production and removal of toxic ammonia.

High levels can indicate ammonia toxicity. Chronic loss of these valuable compounds can contribute to loss of organ reserve and disturbances in neurological function. If they are low they can indicate a need for essential amino acids, especially arginine.

Citric Acid result calculator

insert the value from you Citric Acid test result.

What does it mean if your Citric Acid result is too low?

Possible causes:

  • Low or high pyruvic acid or low acetyCoA (from fatty acid oxidation)

What does it mean if your Citric Acid result is too high?

Impaired metabolism due to toxic metals (Fl, Hg, As, Sb) OR low cofactors (Fe, GSH— depleted in oxidative stress); OR high amounts of dietary citric acid; OR metabolic acidosis (if mildly increased cis-aconitic acid but markedly increased citric acid). High Citrate and Cis-aconitate can indicate arginine insufficiency for ammonia clearance through the Urea Cycle Consider supplementing with arginine Rule out toxic metals; glutathione, N-acetylcysteine, Mg, or L-glutamine; consider antioxidants; rule out pancreatic insufficiency (can lead to metabolic acidosis from deficient bicarbonate).

Possible causes:

  • Impaired metabolism due to toxic metals (Fl, Hg, As)
  • Low glutathione
  • High amounts of dietary citric acid
  • Metabolic acidosis (if mildly increased cis-aconitic acid but markedly increased citric acid)

Additional investigations:

  • Comprehensive Urine Elements Profile
  • Functional Liver Detoxification Profile
  • Complete Digestive Stool Analysis

Treatment considerations:

  • Rule out toxic metals
  • Glutathione
