Active Ingredient Sodium Ascorbate (L-Ascorbic Acid Sodium Salt)
Form Oral Powder (for reconstitution)
Pharmacological Class Vitamin preparation, Essential Nutrient
Common Use Nutritional support for Vitamin C deficiency
Origin Synthetically derived salt form

What is the Primary Classification of C 1000?

C 1000 is fundamentally classified as a Vitamin preparation and Nutritional supplement, falling under the pharmacological category of Essential Nutrients. It functions as a monopreparation, containing a single, high-potency active ingredient. This entity is designed to provide targeted, supplemental levels of Vitamin C, an indispensable water-soluble micronutrient. The classification as an essential nutrient is clinically recognized for its role in preventing deficiencies. This classification confirms that C 1000 provides an essential element the body requires for proper function.


Composition and Form: The Role of Sodium Ascorbate

The active constituent in C 1000 is Sodium Ascorbate, which is the mineral salt of the biologically functional L-Ascorbic Acid (Vitamin C). This compound is synthetically derived and is chosen for specific pharmaceutical attributes, primarily to optimize its properties for oral intake. The formulation's primary differentiation is its high-dose salt form, which ensures high solubility and provides a less acidic compound compared to pure Ascorbic Acid, thereby improving gastrointestinal tolerance in high-dose scenarios. C 1000 is supplied as an Oral Powder in single-dose sachets, intended for oral administration after being mixed immediately with water to form an aqueous solution. The powder form ensures rapid dissolution and absorption once mixed with water.


Why is C 1000 Needed Physiologically?

The physiological need for this preparation stems from the fundamental roles of Vitamin C as a critical Antioxidant and a necessary Cofactor for various enzymatic processes. As an antioxidant, it contributes to the maintenance of physiological resilience by protecting cells from oxidative stress. Furthermore, Vitamin C is essential for the synthesis of collagen, which is vital for the structural integrity and repair of connective tissues, and it facilitates the absorption of non-heme iron from the diet. The preparation is typically used by adults seeking to supplement their intake or those who have confirmed increased physiological requirements for this vitamin.

What side effects are possible with C 1000?

Possible Side Effects and Safety Information


Vitamin C (Ascorbic Acid) is generally considered safe when taken at recommended daily allowances. However, ingesting high doses, such as those found in a 1000 mg supplement, may lead to gastrointestinal side effects, as the body's ability to absorb the vitamin decreases when intake exceeds approximately 400 mg per day, with the excess being excreted.

Common Gastrointestinal Side Effects

At intakes of 1000 mg or more, the most commonly reported side effects are related to the digestive system:

  • Nausea, vomiting, and heartburn
  • Diarrhea and stomach cramps
  • Flatulence or bloating

These symptoms typically resolve once the dosage is reduced or supplementation is discontinued.

Tolerable Upper Intake Level and Other Concerns

The established Tolerable Upper Intake Level (UL) for vitamin C in adults is 2000 mg per day. Consuming amounts above the UL significantly increases the risk of side effects.

Concern Associated Risk Notes
Kidney Stones Increased risk in susceptible individuals, especially those with a history of kidney stones, due to increased urinary oxalate excretion. High-dose supplementation ( ge 1000 mg/day) should be approached with caution.
Drug Interactions Potential interference with medications like the anticoagulant Warfarin, certain chemotherapy and antiviral drugs (e.g., protease inhibitors), and Estrogen-containing oral contraceptives or hormone replacement therapy. Consult a healthcare provider if taking other medications.
Specific Medical Conditions High doses may cause hemolytic anemia in people with Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency, or worsen hemochromatosis (iron overload) by increasing iron absorption. Use is contraindicated or requires medical supervision.

Inform your healthcare provider about your vitamin C supplement use before undergoing certain laboratory tests, such as blood sugar screening tests or stool occult blood tests, as high levels can interfere with the results.

Overdose and Emergency Response

Overdose and when to Seek Help

Overdosage of Sodium Ascorbate (C 1000) is officially documented to present primarily with an exaggeration of its physiological effects. The initial signs often include gastrointestinal disturbances such as nausea, vomiting, indigestion, diarrhea, and stomach cramps. Other systemic manifestations that may be experienced include headache and flushing of the face.

The risk profile for overdosage includes serious, life-threatening outcomes, especially with massive intake or in specific patient populations. High doses are associated with hyperoxaluria and the formation of renal oxalate calculi (kidney stones), potentially leading to acute renal failure or oxalate nephropathy. A key population-specific concern is the documented risk of hemolytic anemia in individuals with Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency. Patients with existing renal impairment are also noted to be at increased risk of severe renal complications.

Due to the potential for severe complications, regulatory authorities mandate that if more than the recommended dose has been taken and adverse symptoms are experienced, individuals must seek immediate medical attention or contact a hospital immediately. Management is officially described as symptomatic and supportive treatment, as no specific antidote is known for Ascorbic Acid overdosage. Hospital monitoring may be required based on the severity and clinical presentation.

Therapeutic Uses of C 1000

C 1000 (Sodium Ascorbate) is a Vitamin C preparation primarily used for therapeutic nutritional support and is relevant in clinical settings that involve acute or unstable symptom patterns caused by deficiency. This class of medication is commonly used to help with Scurvy, a condition associated with symptoms like fatigue, gum swelling, joint pain, and poor wound healing from a lack of the vitamin in the body. It is used to prevent and treat this deficiency.


What C 1000 Treats: Main Uses and Benefits

C 1000 is used to help manage symptom clusters that may become intense or disruptive in conditions characterized by periods of heightened symptoms. The core symptomatic relief it provides relates to symptoms linked to organ-specific functional stress, such as gingival bleeding, easy bruising, and delayed wound healing, alongside systemic symptoms like fatigue and malaise. The supplement is applied across domains where additional symptomatic support is needed, particularly when nutritional gaps or high physiological demands (e.g., in smokers, or post-operative patients) interfere with functional stability.

“Providing this targeted nutritional support helps maintain a sense of stability when symptoms are more noticeable.”

This supportive relief helps improve day-to-day comfort during symptomatic periods and assists with maintaining functional stability in situations where patients experience symptomatic discomfort.


Quick Fact: Relief for Fatigue

Quick Fact: Relief for Fatigue C 1000 is commonly used to help with the symptoms related to physical discomfort and systemic imbalance of fatigue that are characteristic of Vitamin C deficiency.

Eligibility and Restrictions for Use

The use of high-dose Ascorbic Acid (Vitamin C), such as the 1000 mg strength, is defined by strict regulatory exclusions based on metabolic health and population group, rather than general safety. The medicine is contraindicated and must not be used by individuals with:

  • Hypersensitivity to Ascorbic Acid or any excipients.
  • Severe renal impairment or renal failure.
  • Hyperoxaluria (excessive oxalate in urine) or a history of oxalate kidney stones.
  • Iron-overload disorders such as hemochromatosis or thalassaemia, as Ascorbic Acid increases iron absorption.

Restricted or Cautioned Use

The official label mandates caution or dose restriction for specific populations:

Population Regulatory Restriction Practical Implication
Renal Impairment Use is highly restricted; maximum daily limits (e.g., 100-200 mg) must not be exceeded due to kidney stone risk. Severe forms are a contraindication; mild forms require strict dose limits.
G6PD Deficiency High doses must be avoided; the condition carries a risk of hemolysis (red blood cell breakdown). Requires careful use at low doses only, if deemed necessary.
Pediatric Population This dosage strength (ge1000 mg) is not recommended for children and adolescents (typically <18 years). Lower-strength formulations or different age-appropriate products should be used.
Pregnancy/Lactation Use is generally safe at recommended intake levels, but exceeding the usual dosage is not advisable. Avoid high-dose chronic supplementation without explicit monitoring.

What should I know about interactions with other medicines?

Interactions with Other Medicines and Products

The official regulatory profile for C 1000 (Sodium Ascorbate) documents several pharmacokinetic and pharmacodynamic interactions with other medicines and substances. The primary documented interaction mechanisms include its function as a reducing agent and its ability to modify urine pH.

Documented Drug Interactions

The preparation is officially documented to lower the serum concentration of medicines such as Amphetamine and Fluphenazine by making the urine more acidic, thereby increasing their renal excretion. Conversely, administration increases the oral absorption of iron salts and may increase the bioavailability of oral contraceptives, though the contraceptives can lower serum levels of ascorbic acid itself. The official label notes that large doses may reduce the response to oral anticoagulants like Warfarin, and may decrease the activity of certain antibiotics.

Mandatory Restrictions and Administration Rules

A mandatory two-hour separation is required when co-administering the preparation with Deferoxamine, an interaction which has been officially linked to a risk of cardiovascular effects in patients with iron overload. Concurrent use with aluminum-containing antacids is officially not recommended, particularly in patients with renal impairment, due to the potential for increased blood aluminum levels.

Other Interactions and Cautions

Interactions with substances like alcohol and nicotine are officially documented to reduce the body's ascorbic acid levels. Furthermore, C 1000 can interfere with numerous laboratory tests based on oxidation-reduction reactions, potentially leading to inaccurate results for measures such as blood glucose. A specific caution regarding interaction severity is also noted for populations with G6PD deficiency.

Mechanism of Action

C 1000 (Sodium Ascorbate) works by introducing the essential molecule ascorbic acid, which functions as both an essential enzyme cofactor and a dedicated reducing agent across several fundamental biological systems.


Essential Cofactor in Structural Biogenesis

Ascorbic acid is an essential cofactor for prolyl hydroxylase and lysyl hydroxylase, maintaining their active state to allow for the crucial hydroxylation of procollagen. This mechanism is required for the formation of the mature collagen triple helix, thereby contributing to the structural organization of connective tissue and vascular walls.


️ Regulation of Cellular Redox Balance

The molecule acts as a primary water-soluble antioxidant and reducing agent, directly engaging mechanisms that neutralize molecular damage. It achieves this by rapidly neutralizing Reactive Oxygen Species (ROS) and other free radicals via electron donation, preventing peroxidative damage to lipids and DNA. This action results in the scavenging of free radicals and the preservation of membrane lipids during oxidative events.


Neurotransmitter Synthesis Pathway

Ascorbic acid is a necessary cofactor for the enzyme dopamine beta-hydroxylase, which performs the conversion of dopamine into the key catecholamine norepinephrine. This synthesis pathway maintains the necessary concentration gradient for catecholamine signaling in the central nervous system and adrenal gland.

Dosage and Administration Information

C 1000 (Sodium Ascorbate) is strictly intended for oral administration and is not to be used by other routes. As an oral powder, the preparation requires the dose to be mixed thoroughly with water or a soft food immediately prior to consumption. It is essential that the prepared solution is taken immediately, and no mixture should be stored for later use, to ensure the stability of the compound. The medicine may be taken with or without food.

The standard therapeutic course for treating Vitamin C deficiency (scurvy) requires a daily dose between 100 mg and 500 mg for adults. This daily amount is typically administered once daily or may be divided into two daily doses. The treatment must be continued for a minimum duration of two weeks to ensure resolution of the deficient state. Usage of C 1000 should not exceed the established Tolerable Upper Intake Level (UL) of 2,000 mg per day for adults. Specific instructions advise caution when administering the preparation to patients who have existing renal impairment or a predisposition to calcium oxalate stones.

The official administration protocol requires immediate reconstitution of the powder and adherence to the daily dose range and duration. This protocol defines the standardized, label-based approach for using the medicine.
