Ascorbic acid, more commonly known as vitamin C, is a water-soluble micronutrient indispensable for numerous physiological functions. As a potent antioxidant, it plays a critical role in neutralizing free radicals, thereby mitigating oxidative stress and supporting cellular integrity. Its biochemical necessity extends to collagen synthesis, immune modulation, and enhanced iron absorption, making it a cornerstone of preventive and therapeutic nutrition. This high-purity formulation ensures maximum bioavailability for targeted physiological support, adhering to stringent pharmaceutical-grade standards for efficacy and safety.
Features
- Pharmaceutical-grade L-ascorbic acid (99.9% purity)
- Water-soluble crystalline powder for flexible dosing
- Enhanced bioavailability with no unnecessary excipients
- Synthesized under cGMP (current Good Manufacturing Practices) conditions
- Third-party tested for heavy metals, microbial contamination, and potency verification
- Stable molecular structure with a shelf life of 36 months when stored appropriately
Benefits
- Supports robust immune function by enhancing neutrophil and lymphocyte activity
- Promotes collagen biosynthesis for healthy skin, joints, and vascular integrity
- Acts as a potent antioxidant, reducing oxidative damage to lipids, proteins, and DNA
- Facilitates non-heme iron absorption, aiding in the prevention of iron-deficiency anemia
- Contributes to neurological health through its role in neurotransmitter synthesis
- May reduce the duration and severity of upper respiratory tract infections
Common use
Ascorbic acid is routinely utilized in clinical and self-care contexts for the prevention and treatment of vitamin C deficiency, which may present as scurvy, fatigue, or impaired wound healing. It is widely recommended during periods of increased oxidative stress, such as infection, inflammation, smoking, or environmental toxin exposure. Athletes and individuals under physical duress may use it to support recovery and mitigate exercise-induced oxidative damage. Dermatological applications include supporting skin health and anti-aging regimens due to its role in collagen production and photoprotection.
Dosage and direction
The recommended dietary allowance (RDA) for adult men is 90 mg/day and for adult women is 75 mg/day. Higher doses—typically ranging from 200 mg to 1000 mg daily—are often used therapeutically under medical supervision. For general supplementation, 250–500 mg once or twice daily with meals is common to enhance absorption and minimize gastric discomfort. Soluble powder forms may be dissolved in water or juice. Dosage should be individualized based on health status, lifestyle, and specific physiological demands. Consult a healthcare provider for personalized dosing guidance.
Precautions
Ascorbic acid is generally well-tolerated but should be used cautiously in individuals with a history of oxalate kidney stones, hemochromatosis, or glucose-6-phosphate dehydrogenase (G6PD) deficiency. High doses may cause gastrointestinal disturbances such as diarrhea or abdominal cramps. Patients with renal impairment should avoid megadoses due to reduced clearance. Pregnant or breastfeeding women should not exceed the tolerable upper intake level of 2000 mg/day without medical advice. Discontinue use if hypersensitivity reactions occur.
Contraindications
Ascorbic acid is contraindicated in patients with known hypersensitivity to any component of the formulation. It should not be used in those with hereditary iron overload disorders (e.g., hemochromatosis) due to enhanced iron absorption. Use with caution or avoid in patients with a history of recurrent calcium oxalate nephrolithiasis. Not recommended for individuals undergoing certain chemotherapy regimens or radiation therapy without oncologist approval, as it may interfere with treatment efficacy in specific contexts.
Possible side effects
Most adverse effects are dose-dependent and reversible. Common side effects include gastrointestinal discomfort, nausea, diarrhea, and abdominal cramps at doses exceeding 1000 mg per day. High doses may lead to acidification of urine and increased oxalate excretion, potentially elevating the risk of nephrolithiasis in susceptible individuals. Rarely, dizziness, headache, or flushing may occur. Very high intravenous doses have been associated with hemolysis in patients with G6PD deficiency.
Drug interactions
Ascorbic acid may interact with several medications. It can increase aluminum absorption from aluminum-containing antacids, potentially leading to toxicity in renal impairment. It may elevate estrogen levels when taken with oral contraceptives or hormone replacement therapy. Concurrent use with anticoagulants like warfarin may modestly reduce anticoagulant effect. Ascorbic acid can also interfere with certain chemotherapeutic agents (e.g., bortezomib) and should be used cautiously under oncology supervision. It may alter urine glucose test results in diabetic patients.
Missed dose
If a dose is missed, take it as soon as remembered unless it is nearly time for the next scheduled dose. Do not double the dose to make up for a missed one. Consistency supports stable plasma levels, but occasional missed doses are unlikely to cause acute deficiency due to the compound’s storage capacity in tissues and gradual depletion.
Overdose
Acute overdose is rare due to efficient renal excretion, but extremely high doses (≥3–4 g in a single intake) may cause severe diarrhea, nausea, vomiting, or gastritis. Management is supportive and includes discontinuation, hydration, and symptomatic care. Chronic excessive intake (≥2 g/day) may lead to oxalate nephropathy or nephrolithiasis. In case of suspected overdose, seek medical attention or contact a poison control center.
Storage
Store in a cool, dry place away from direct light, moisture, and heat. Keep the container tightly sealed to prevent oxidation and degradation. Ideal storage temperature is between 15–30°C (59–86°F). Do not refrigerate unless specified by the manufacturer. Keep out of reach of children and pets. Discard any product that shows signs of discoloration, clumping, or unusual odor.
