471-34-1 | Calcium Carbonate

Chemical type

• Inorganic carbonate mineral
• Alkaline earth metal salt

^[1]

• Inorganic calcium salt

^[2]

Key properties

• Low solubility in water
• Thermodynamically stable solid
• Long-term carbon storage form

^[1]

• High calcium content (~40% elemental calcium) and low cost
• Weakly alkaline salt with poor solubility in neutral intestinal pH
• Dissociates into Ca²⁺ and CO₃²⁻ in the gut, locally raising pH and potentially disrupting microbial niches
• Associated with gastrointestinal side effects (constipation, abdominal discomfort), possible cardiovascular risk, and kidney stones

^[2]

• Solid carbon storage product in Direct Ocean Capture (DOC)
• Precipitated from carbonate-rich streams after pH elevation
• Stored on land for durable (>1,000 years) carbon sequestration

^[1]

• Primary oral calcium supplement for osteoporosis prevention and treatment
• Intended to maintain bone mass and mineral density
• In senile osteoporosis models: minimal or no significant improvement in bone microarchitecture, trabecular parameters, osteogenic differentiation of BMMSCs, or bone formation rates (MAR, BFR/BS); instead exacerbates age-related gut dysbiosis, reduces intestinal barrier integrity (↓ ZO-1, Claudin-1, Occludin protein levels), increases gut permeability, elevates proinflammatory cytokines (TNF-α, IL-17A), and worsens systemic inflammation

^[2]

Classification by use

• Chemicals used for long-term carbon storage
• Chemicals used in mineral carbonation
• Chemicals used as solid sequestration media

^[1]

• Chemicals used in nutritional/dietary supplements
• Chemicals used for osteoporosis prevention and bone health maintenance
• Calcium supplements (inorganic salts)
