Citric Acid

Last Updated: September 28 2022

Citric Acid is an intermediate in the Krebs Cycle, and technically crucial for cellular functioning and energy production. Its usage in supplements includes useful things like being bound to minerals (such as Calcium Citrate or Magnesium Citrate) to increase water solubility.

Citric Acid is most often used for


Citric acid is a compound that, in the body, is created for production of cellular energy via the TCA cycle. Supplementation with it has not been shown to increase energy levels as enough is made by the body.

It has an alkalinizing effect on the body when ingested and has been shown in a limited amount of studies to exert some protection against calcium loss in post-menopausal osteroporetic women.

What else is Citric Acid known as?
Note that Citric Acid is also known as:
  • Citrate
Dosage information

Alkalinizing effects of Citric acid supplementation have been shown in high doses of 0.1g/kg bodyweight, which is 8.2g a day for a 180lb person.
