1. Introduction

Calcium citrate is a white, odorless powder that is insoluble in water and ethanol.

In the food industry, calcium citrate serves as a:

Common uses: Dairy products, jams, beverages, flour, confectionery, and baked goods.

Organic calcium source with ~21% elemental calcium content.
Superior bioavailability compared to inorganic calcium (e.g., carbonate, phosphate, sulfate):
- Absorption rate: 22–27% (vs. calcium carbonate’s 15–20%).
- Gastric acid-independent absorption: No gastrointestinal irritation; does not require stomach acid for solubilization.
- Controlled ion release: Degrades efficiently, providing stable calcium ions—ideal for biomedical applications (e.g., supporting early-stage bone fracture healing).

Additional benefits:

Anticoagulant properties: Helps prevent hypertension and myocardial infarction.
Clinically preferred for calcium supplementation.

The citrate moiety participates in the tricarboxylic acid (TCA) cycle, generating:
- ATP (cellular energy)
- CO₂ and water (metabolic byproducts)
Key roles:
- Fat metabolism: Enhances lipid breakdown and acid-base balance.
- Lactate clearance: Converts lactic acid (fatigue-inducing metabolite) into usable energy, breaking the “fatigue cycle” (common in obesity).
- Performance enhancement: Used by athletes to maintain peak physical condition via improved oxygen/nutrient delivery.

Dual function:
1. High-purity calcium source
2. Gut health modulator:
  - Lowers gastric pH → activates pepsinogen (improves protein digestion).
  - Compensates for low HCl secretion in piglets, reducing diarrhea incidence.
  - Antimicrobial action: Inhibits E. coli; promotes Lactobacillus growth.
