Origin Essential nutrients

What Type of Supplement is Cavic C?

Cavic C is formally classified as a specific mineral and vitamin combined preparation (A11GB01 in the WHO ATC classification system), functioning as an over-the-counter nutritional supplement. This formulation is designed to deliver two essential micronutrients simultaneously. The components are essential because humans must obtain them externally; for instance, Ascorbic acid must be supplied by the diet, as the body cannot produce its own Vitamin C.

This combination product is clinically recognized for its role in preventing deficiencies, particularly in patient groups with increased nutritional requirements or inadequate dietary intake. The product's classification as an essential nutrient supplement emphasizes its role in maintaining foundational physiological systems.


What are the Main Ingredients and Form?

The active ingredients in Cavic C are Calcium (derived from a combination of Calcium lactate gluconate and Calcium carbonate) and Ascorbic acid (Vitamin C). It is notably manufactured as an effervescent tablet intended for oral administration after dissolving in water.

This effervescent format is a distinct advantage: it ensures the ingredients are already dissolved before ingestion, potentially offering a more patient-friendly option than hard tablets. The dual-salt composition (lactate gluconate and carbonate) is a specific feature intended to balance high elemental calcium content with optimal solubility, a design often favored for liquid administration.


What is the General Purpose of Cavic C?

Its general purpose is to prevent and correct deficiencies of both calcium and Vitamin C, which are critical for maintaining the body's structural integrity and immune defenses. By supplying the mineral, it supports key functions such as bone maintenance and nerve signaling. By supplying Vitamin C, it supports the synthesis of collagen and acts as an important antioxidant.

A typical scenario for its use is supplementing the diet of individuals who need increased support for bone health or immune function. The product is fundamentally designed to maintain a healthy physiological state by ensuring adequate intake of these two vital, co-dependent nutrients.

What side effects are possible with Cavic C?

Possible Side Effects and Safety Information

The safety profile of Cavic C, a combination of Calcium and Ascorbic Acid (Vitamin C), is primarily defined by effects on the Gastrointestinal and Metabolism and Nutrition systems, as documented in official regulatory labeling.

Frequency and System Classification

Gastrointestinal disturbances such as constipation, flatulence, nausea, vomiting, diarrhea, and abdominal pain are noted in official documents. Effects on mineral balance, specifically Hypercalcaemia (elevated blood calcium) and Hypercalciuria (elevated urinary calcium), are also documented.

Classification Examples of Documented Effects
Uncommon Hypercalcaemia, Hypercalciuria
Rare Gastrointestinal disturbances, Hypersensitivity reactions (e.g., rash)
Very Rare Severe systemic hypersensitivity (e.g., Anaphylaxis)

Serious Reactions and Specific Safety Considerations

Official labels detail serious risks tied to patient-specific conditions or long-term high-dose use. Patients with impaired renal function require medical supervision and monitoring of serum calcium and phosphate levels when using calcium salts. Individuals with a history of urinary concrements or mild hypercalciuria also require specific monitoring.

There is a documented risk of Severe Hemolysis for patients with Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency due to the Ascorbic Acid component. Furthermore, the development of oxalate nephropathy (a kidney condition) is associated with prolonged high-dose use of Ascorbic Acid in susceptible individuals.

Safety Restrictions

The calcium component can interfere with the absorption of certain oral medications, such as specific antibiotics (tetracycline and fluoroquinolone preparations). Official regulatory documents specify the need for a mandated time gap between the administration of the supplement and these medications.

Overdose and Emergency Response

Overdose and When to Seek Help

Overdose of Cavic C, particularly acute or chronic exposure to high doses of the Vitamin D component, can lead to a serious medical condition known as hypercalcaemia (excessive calcium in the blood). The primary symptoms and health risks associated with this condition arise from the resulting Vitamin-D toxicity.


Potential Overdose Manifestations

The documented signs and symptoms that may indicate an overdose include:

Physiological System Documented Manifestation Context
Gastrointestinal Nausea, vomiting, and constipation Early symptoms of toxicity
Renal/Urinary Polyuria (excessive urination) Result of high calcium levels
Chronic Risk Vascular and organ calcification Result of long-term, chronic overdose-induced hypercalcaemia

Emergency Action and Medical Attention

If an overdose is suspected, the most serious consequence is high calcium in the blood, which requires immediate attention to prevent severe, long-term complications. The required initial response is:

  • Stop all intake of calcium and Vitamin-D supplements.
  • Initiate rehydration (increasing fluid intake).

Urgent medical attention is necessary if any symptoms of hypercalcaemia, such as persistent nausea, vomiting, or excessive thirst/urination, are present. You should contact a healthcare professional or emergency services for guidance on the required treatment and supportive care, as unchecked hypercalcaemia can be harmful to the kidneys and other organs.

Therapeutic Uses of Cavic C

What Cavic C Treats: Main Uses and Benefits

Cavic C is commonly used to address symptoms related to systemic imbalance that stem from a lack of Calcium and Ascorbic Acid (Vitamin C). This combination is applied across domains where additional symptomatic support is needed to support general well-being during symptomatic phases.

The supplement is relevant for easing challenging symptoms associated with several conditions, including Calcium deficiency (Hypocalcaemia), Vitamin C deficiency (Scurvy), and is used as supportive management for Osteoporosis. It is also applied in contexts involving heightened systemic burden, such as convalescence and rapid growth phases.

The product plays a role in managing structural stability and supports systemic resilience. The product contributes to improved comfort by supporting essential nutrient levels, which assists with maintaining functional stability during demanding phases of life.

“It helps address symptom clusters that may become intense or disruptive due to nutritional insufficiency, supporting the body’s natural stability.”

What should I know about interactions with other medicines?

Interactions with other medicines and products

The official interaction profile for Cavic C is defined by the chemical properties of its two active components, Calcium and Ascorbic Acid, establishing specific procedural constraints and detailing specific toxicity risks.

Chelation-Mediated Reduction in Absorption

Co-administration of the calcium component with certain medicinal products results in a significant reduction in the oral absorption and systemic exposure of the co-administered drug. This pharmacokinetic interaction requires a mandatory separation of doses to ensure the efficacy of agents such as Levothyroxine (thyroid hormone), Bisphosphonates, and Tetracycline or Quinolone Antibiotics.

Pharmacodynamic and Toxicity Risks

The calcium component is documented to enhance the toxicity of Cardiac Glycosides (e.g., Digoxin), which is associated with an increased risk of arrhythmias. Co-administration with Thiazide Diuretics is noted to increase the risk of hypercalcemia due to reduced urinary calcium excretion.

Ascorbic Acid and Substance-Specific Cautions

The ascorbic acid component increases the absorption of Aluminum from aluminum-containing antacids, posing an elevated risk of aluminum toxicity, particularly in patients with severe renal impairment. Furthermore, high doses of Ascorbic Acid are officially noted to be associated with hemolysis in individuals with Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency. In the dietary context, foods high in Oxalic or Phytic Acid are also noted to decrease calcium absorption.

Mechanism of Action

Cavic C comprises calcium salts and ascorbic acid (Vitamin C). Its mechanism involves two distinct, non-interacting pharmacodynamic pathways.

Ascorbic Acid Pathway

Ascorbate, the reduced form of Vitamin C, functions as a water-soluble electron donor, primarily via its action as a cofactor for numerous hydroxylase and dioxygenase enzymes. Specifically, it is an essential cofactor for prolyl and lysyl hydroxylases, enzymes critical for the post-translational hydroxylation of proline and lysine residues, which is required for the triplex helix formation of procollagen and subsequent collagen maturation in tissues. Furthermore, ascorbate functions as a reducing agent in intracellular and extracellular compartments, recycling alpha-tocopherol (Vitamin E) and directly neutralizing reactive oxygen species. This activity is vital in regulating cellular redox status and influencing the transcription of target genes, particularly in osteoblasts.

Calcium Pathway

Calcium, supplied as calcium lactate gluconate and carbonate, increases the concentration of circulating ionized calcium ( Ca^2+). This Ca^2+ binds to specific calcium-sensing receptors, initiating cascades that modulate membrane potential and neurotransmitter release. At the system level, the increased plasma Ca^2+ concentration contributes to the mineral ion pool, directly supporting the physical deposition of calcium phosphate compounds within the bone matrix via osteoblastic activity.

Dosage and Administration Information

How Cavic C is Used

Cavic C is administered exclusively through the oral route, a method dictated by its dosage form as an effervescent tablet. The proper use of the medicine is structured around a mandatory preparatory step: the tablet must be fully dissolved in a glass of water before it is consumed, and the resulting solution should be drunk immediately upon preparation. Swallowing the effervescent tablet whole is not the correct administration procedure.

The standard pattern of use is a once-daily regimen, a common approach for maintaining essential nutrient levels. The dose is fixed and varies based on the user's age group, as established in the product's instructions. For adults and children over 7 years, the standard dose is one effervescent tablet daily. Younger patients, specifically children aged 3 to 7 years, require a reduced daily dose of half an effervescent tablet. Infants require dosage guidance directly from a physician.

Cavic C is generally used as part of a long-term plan for maintenance in chronic conditions, or for a short-term course aimed at correcting an established nutritional deficit. If a standard dose is missed, a patient typically resumes the once-daily schedule with the next scheduled dose, as there are no specific supplemental instructions for missed timing. The simplicity of the once-daily, fixed-dose regimen defines the non-advisory use protocol for this specific mineral and vitamin combination.

Recent Clinical Evidence

Research Evidence: Overview of Studies for Cavic C

Evidence for Use in Nutrient Status

Research was studied for exploring conditions characterized by systemic imbalance, specifically when low levels of calcium (Hypocalcemia) and Vitamin C (Scurvy) are present. The evidence base includes foundational historical intervention trials, systematic reviews, and pharmacokinetic studies that examine ingredient uptake. These studies measured outcomes related to the evolution of the imbalance, such as the concentration of nutrients in the bloodstream and the monitoring of physiological indicators like Parathyroid Hormone (PTH) levels. While the necessity of correcting a diagnosed deficiency is established in foundational research, evidence quality varies across studies, and long-term effects of this specific formulation on the durability of correction are not fully established.


Evidence for Supportive Use in Structural Health

The combination was studied for supportive use in conditions marked by functional limitations, such as osteoporosis. Research examined outcomes including Bone Mineral Density (BMD) and the occurrence of fractures. The evidence primarily consists of large-scale meta-analyses and Randomized Controlled Trials (RCTs) where calcium was studied. Findings describe patterns of association between calcium intake and measures of bone strength. However, the specific combination has not been directly evaluated in large RCTs for fracture reduction; comparative evidence remains insufficient. The role of supplemental Vitamin C in structural health findings was largely explored in observational settings.


Research Limitations and Uncertainty

Research has explored the product for general nutritional support in special groups like older adults, children during rapid growth, and individuals in convalescence. Evidence is limited regarding a direct impact on outcomes reflecting daily functioning in these groups. Overall, a key research limitation is that comparative evidence between the dual-salt effervescent combination and single-nutrient alternatives remains insufficient. Results apply only to the specific populations studied, and long-term effects are not fully established across all indications.
