Ingredient Information
Summary
Citric Acid is a weak organic acid naturally found in citrus fruits such as lemons, limes, and oranges. It is commonly used in food and supplements as a flavour enhancer, preservative, and acidity regulator. In the body, citric acid plays a role in the Krebs cycle, a key energy-producing process in cells. It can also support mineral absorption, particularly of calcium and magnesium. People who may benefit from citric acid include those looking for improved energy metabolism or better mineral uptake. It is also widely used in supplements to stabilise active ingredients and improve taste.

What Is Citric Acid?
Citric acid is a naturally occurring weak acid first isolated from lemon juice in 1784 by the chemist Carl Wilhelm Scheele. Chemically, it is a tricarboxylic acid with the formula C₆H₈O₇. In its pure form, citric acid is a white, crystalline powder with a tart taste. It is widely used in food, beverages, and supplements as a flavouring and preservative due to its natural acidity. In the body, citric acid is a central component of the citric acid cycle (also known as the Krebs cycle), which is essential for producing cellular energy.
How It Works In The Body
Citric acid works in the body by acting as an intermediate in the citric acid (Krebs) cycle, a process that generates energy from carbohydrates, fats, and proteins. This cycle is vital for the production of ATP, the body’s main energy currency. Citric acid also enhances the solubility and absorption of certain minerals, such as calcium, magnesium, and potassium, making them more bioavailable. Its natural acidity helps maintain pH balance in foods and supplements, contributing to stability and effectiveness.
Safety & Interactions
- Citric acid is generally recognised as safe when consumed in food or supplement amounts.
- Excessive intake may cause stomach upset, heartburn, or erosion of dental enamel due to its acidity.
- People with sensitive stomachs or acid reflux may wish to limit high intakes of citric acid.
- In supplement formulations, citric acid is typically well tolerated and used to aid stability and absorption.
- Pregnant and breastfeeding women can safely consume citric acid from foods but should consult a healthcare professional before using high-dose supplements.
Always consult your health practitioner before taking nutritional supplements, especially if you are taking medication or are under medical supervision. You should not take supplements as a substitute for a varied balanced diet or healthy lifestyle.
FAQs
Is citric acid safe to consume every day?
Yes, citric acid is safe for daily consumption at normal dietary levels. It is naturally present in many fruits and widely used in food and supplements.
What is citric acid used for in supplements?
Citric acid is often added to supplements as a preservative, flavour enhancer, or to improve the absorption of minerals such as calcium and magnesium.
Can citric acid cause side effects?
At typical doses, citric acid is well tolerated. In large amounts, it may contribute to digestive discomfort or, if consumed frequently in acidic drinks, dental enamel erosion.
