Ingredient Information
Summary
Trisodium Citrate, also known as sodium citrate, is the sodium salt of citric acid. It is commonly used in food, beverages, and supplements as an acidity regulator, preservative, and stabiliser. In the body, trisodium citrate can act as an alkalising agent, helping to maintain normal acid–base balance. It also supports the absorption of minerals and is often included in formulations to improve taste and stability. People who may benefit from trisodium citrate include those seeking better mineral utilisation or products designed for digestive comfort and electrolyte balance.
Key Facts
- Type: Mineral salt (sodium salt of citric acid)
- Natural source: Citrus fruits (derived from citric acid)
- Typical supplemental dose: 500–1,500 mg per day (varies by use)
- Used for: Acid–base balance, mineral absorption, electrolyte support, preservative function
- First discovered: 19th century
What Is Trisodium Citrate?
Trisodium citrate is the fully neutralised sodium salt of citric acid, with the chemical formula Na₃C₆H₅O₇. It typically appears as a white, crystalline powder that dissolves easily in water and has a slightly salty, sour taste. It is widely used in foods and supplements as a flavour enhancer, buffering agent, and preservative. In supplements, trisodium citrate helps stabilise active ingredients, regulate acidity, and improve palatability. It is also used medically as an alkalising agent to reduce acidity in the body.
How It Works In The Body
Trisodium citrate works by dissociating into sodium and citrate ions in the body. The citrate component enters the citric acid (Krebs) cycle, supporting normal energy metabolism, while its alkalising effect helps maintain acid–base balance. Sodium citrate can also enhance the solubility and absorption of certain minerals, particularly calcium and magnesium, improving their bioavailability. As an electrolyte, the sodium content contributes to fluid balance and hydration.
Safety & Interactions
- Trisodium citrate is generally recognised as safe when consumed in normal dietary and supplemental amounts.
- Excessive intake may contribute to high sodium levels, which can raise blood pressure or cause fluid retention in sensitive individuals.
- People with kidney disease, hypertension, or sodium-restricted diets should use caution with trisodium citrate.
- It may interact with medications that affect electrolyte balance or kidney function.
- Pregnant and breastfeeding women can safely consume trisodium citrate in foods, but should consult a healthcare professional before taking it in supplement form.
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
What is trisodium citrate used for in supplements?
It is mainly used as a stabiliser, acidity regulator, and to improve the absorption of minerals like calcium and magnesium.
Is trisodium citrate safe for daily consumption?
Yes, it is safe when consumed within normal dietary or supplemental levels, though those on sodium-restricted diets should monitor intake.
Does trisodium citrate have health benefits?
Beyond its role as a food additive, trisodium citrate may support mineral absorption, acid–base balance, and hydration, making it useful in some supplement and medical contexts.
