Calcium citrate is a synthetic calcium salt supplement supporting bone health and muscle function, well-absorbed even with low stomach acid.
Calcium citrate is a synthetically produced calcium salt used as a dietary supplement to support bone health, muscle function, and nerve transmission. Its advantage lies in its superior absorption, particularly in individuals with low stomach acid. While generally safe, potential side effects include gastrointestinal discomfort and an increased risk of kidney stones with excessive doses. It is crucial to consider potential drug interactions and consult with a healthcare professional before initiating calcium supplementation.

Inside BodyPotential Benefits
Enhances bone density, strength, and integrity by supporting bone formation, calcium absorption, and reducing age-related bone loss. Improves overall skeletal health and function, ultimately reducing the risk of fractures.
Enhances and maintains the proper functioning of muscles, improving strength, power, endurance, and coordination. Optimal muscle function is crucial for mobility, balance, posture, and reduces risk of injury.
Calcium is essential for nerve impulse transmission by enabling neurotransmitter release, which supports communication between nerve cells. This process is crucial for cognitive function, muscle control, and overall nervous system health.
Calcium citrate is more easily absorbed than calcium carbonate, especially in individuals with low stomach acid. This enhanced absorption ensures greater calcium bioavailability for essential bodily functions.
Possible Side Effects
High vitamin D can cause high calcium, leading to nausea and weakness.
Constipation involves infrequent or difficult bowel movements, resulting in hard, dry stools. It can be triggered by factors such as poor diet, dehydration, medication, or underlying medical conditions.
Long-term high calcium from vitamin D may increase kidney stone risk.
Gas and bloating are common but usually transient gastrointestinal side effects resulting from changes in gut bacteria during probiotic use, causing fermentation and gas production.
Drug interactions can alter a drug's effectiveness, leading to either increased risk of blood clots or bleeding, particularly with anticoagulants. Monitoring is essential to manage these interactions.
Scientific Evidence
Numerous studies support the role of calcium in bone health and muscle function. Research compares the bioavailability of different calcium forms, including calcium citrate and calcium carbonate, particularly in relation to gastric acidity. Guidelines from organizations like the National Osteoporosis Foundation and the Institute of Medicine provide recommendations for calcium intake.
