Calcium Disuccinate
Also known as: Calcium supplements, Calcium carbonate, Calcium citrate, Calcium gluconate, Calcium disuccinate, Calcium
Overview
Calcium is an essential mineral vital for bone health, muscle function, nerve transmission, and various other bodily functions. It is naturally found in dairy products, leafy greens, and fortified foods. Calcium supplements are commonly used to prevent osteoporosis and treat conditions like hypocalcemia. These supplements come in various forms, including calcium carbonate and calcium citrate, which differ in their bioavailability. Research on calcium supplementation is extensive, with strong evidence supporting its benefits for bone health. However, some studies suggest potential cardiovascular risks, particularly in postmenopausal women. Therefore, it's crucial to consider individual health conditions and consult healthcare providers before starting calcium supplementation. The effectiveness of calcium supplements is also influenced by factors such as age, supplement form, and concurrent intake of vitamin D, which enhances calcium absorption. Overall, calcium supplementation is a well-researched area with generally positive outcomes for bone health when used appropriately.
Benefits
Calcium supplementation significantly improves bone mineral density (BMD) and bone mineral content (BMC), particularly in young adults aged 20-35, a critical period for achieving peak bone mass. Meta-analyses have shown that calcium supplementation increases BMD at the femoral neck (SMD = 0.627, 95% CI: 0.338–0.915) and total body (SMD = 0.330, 95% CI: 0.163–0.496). These beneficial effects on bone health can be maintained for at least one year after intervention. However, some evidence suggests potential cardiovascular risks, particularly in postmenopausal women, where calcium supplements may increase the risk of cardiovascular disease by about 15%. Therefore, the benefits of calcium supplementation are most pronounced for bone health, especially in younger adults, but potential cardiovascular risks should be considered, particularly for postmenopausal women.
How it works
Calcium primarily works by being incorporated into bone tissue, thereby enhancing bone density and strength. It plays a critical role in bone metabolism, interacting primarily with the skeletal system but also affecting muscle function and nerve transmission. Calcium ions are essential for various cellular processes, including muscle contraction and neurotransmitter release. The absorption of calcium varies depending on the supplement form; calcium citrate is often more bioavailable than calcium carbonate. Vitamin D enhances calcium absorption, making it a crucial cofactor for optimal calcium uptake and utilization in the body.
Side effects
Calcium supplements are generally considered safe when taken appropriately, but excessive intake can lead to adverse effects. Common side effects (occurring in >5% of users) include gastrointestinal symptoms like constipation and bloating. Uncommon side effects (1-5%) may include kidney stones and calcification in soft tissues. Rare side effects (<1%) involve hypercalcemia, which can lead to more serious health issues. Calcium supplements may interact with certain medications, such as tetracycline antibiotics. Contraindications include conditions like hypercalcemia or kidney stones. Postmenopausal women may face increased cardiovascular risks with high doses of calcium supplements. It is important to adhere to recommended dosage guidelines and consult a healthcare provider, especially for individuals with pre-existing health conditions or those taking other medications.
Dosage
The minimum effective dose of calcium is typically around 500 mg per day for bone health benefits. The optimal dosage range is often recommended to be between 500-1000 mg per day for general health. The Tolerable Upper Intake Level (UL) is 2500 mg per day for adults. Calcium supplements are best taken with meals to enhance absorption. Calcium citrate may be preferred for better absorption compared to calcium carbonate. Vitamin D is essential for optimal calcium absorption and should be taken concurrently. Individual needs may vary based on age, health status, and dietary calcium intake, so consulting a healthcare provider is advisable to determine the appropriate dosage.
FAQs
How much calcium should I take daily?
The recommended daily intake varies by age and health status, but generally, 500-1000 mg is sufficient. Consult with a healthcare provider for personalized advice.
Are calcium supplements safe for everyone?
Generally safe, but individuals with certain health conditions, such as hypercalcemia or kidney stones, should consult a healthcare provider before taking calcium supplements.
When is the best time to take calcium supplements?
Calcium supplements are best taken with meals to improve absorption. Dividing the daily dose into smaller amounts taken throughout the day can also enhance absorption.
What can I expect from taking calcium supplements?
Improved bone health over time is the primary expected benefit. However, individual results may vary, and calcium supplements should be part of a comprehensive bone health strategy.
Do calcium supplements always prevent osteoporosis?
While beneficial for bone health, they do not guarantee prevention of osteoporosis. A balanced diet, regular exercise, and other lifestyle factors also play crucial roles.

- https://pubmed.ncbi.nlm.nih.gov/36164828/ – This systematic review and meta-analysis, involving 7,382 participants under 35 years old, found that calcium supplementation significantly improves bone mineral density (BMD) and bone mineral content (BMC), particularly in the femoral neck and total body. The study highlights the importance of calcium supplementation during the crucial period for achieving peak bone mass, although it notes heterogeneity between studies.
- https://elifesciences.org/articles/79002 – This study provides further evidence supporting the benefits of calcium supplementation on bone health. The research reinforces the importance of calcium intake for maintaining and improving bone density, particularly in younger adults. The findings contribute to the understanding of how calcium supplementation can positively impact skeletal health.
- https://www.mdpi.com/2072-6643/13/2/368 – This meta-analysis focused on postmenopausal women and found that calcium supplements may increase the risk of cardiovascular disease by about 15%. The study suggests that while calcium is beneficial for bone health, potential cardiovascular risks should be considered, especially in postmenopausal women, warranting careful evaluation of calcium supplementation in this population.
- https://www.medrxiv.org/content/10.1101/2022.04.14.22273724v1 – This systematic review indicates that calcium supplementation benefits bone health, but the effects can vary based on age and supplement form. The research underscores the importance of considering individual factors when recommending calcium supplementation, as the effectiveness can differ across populations and with different types of calcium supplements.
