Ascorbic acid, the pure and bioactive form of Vitamin C, is a fundamental micronutrient indispensable for human health. As a potent water-soluble antioxidant, it plays a critical role in neutralizing free radicals, supporting collagen synthesis, and enhancing immune function. Unlike esterified or buffered forms, pure L-ascorbic acid offers uncompromised bioavailability and rapid systemic uptake, making it the gold standard for therapeutic supplementation and clinical research. Its utility spans from preventative health to adjunctive therapy in oxidative stress-related conditions.
Features
- Pharmaceutical-grade L-ascorbic acid (≥99.9% purity)
- Water-soluble crystalline powder form
- pH approximately 2.2–2.5 (acidic, enhancing stability)
- Molecular weight: 176.12 g/mol
- Melting point: 190–192°C (with decomposition)
- Readily oxidizes in air, light, and alkaline solutions
- Fully bioidentical to endogenous vitamin C
- No additives, excipients, or flow agents
Benefits
- Enhances immune cell function, including neutrophil phagocytosis and lymphocyte proliferation
- Serves as an essential cofactor for enzymes involved in collagen biosynthesis, supporting vascular integrity, skin health, and wound healing
- Potent antioxidant activity scavenges reactive oxygen species (ROS), reducing oxidative damage to lipids, proteins, and DNA
- Facilitates dietary iron absorption by reducing ferric iron (Fe³⁺) to ferrous iron (Fe²⁺)
- Supports neurotransmitter synthesis, including catecholamines, through its role as a cofactor for dopamine beta-hydroxylase
- May reduce the duration and severity of upper respiratory tract infections in physically stressed populations
Common use
Ascorbic acid is widely utilized in both clinical and preventive contexts. It is commonly indicated for the prevention and treatment of vitamin C deficiency, manifesting as scurvy. In integrative and nutritional medicine, it is employed to support immune function, particularly during periods of increased physiological demand. It is also used adjunctively in conditions characterized by elevated oxidative stress, including cardiovascular diseases, certain cancers, and inflammatory disorders. Topically, it is formulated in dermatological preparations for its antioxidant and collagen-stimulating properties.
Dosage and direction
Dosage should be individualized based on nutritional status, clinical context, and tolerance. For general supplementation, adults may take 250–1000 mg daily in divided doses. Higher doses, sometimes reaching several grams per day, may be used under medical supervision for specific therapeutic aims. To minimize gastrointestinal discomfort, it is advisable to take with food and adequate water. For individuals with sensitive digestion, titration from a lower dose is recommended. Powder forms may be dissolved in water or juice. Do not chew or hold tablets in the mouth to avoid potential enamel erosion.
Precautions
Consult a healthcare provider before use if you have a history of kidney stones, hemochromatosis, glucose-6-phosphate dehydrogenase (G6PD) deficiency, or renal impairment. Discontinue use and seek medical advice if rash, dizziness, or persistent gastrointestinal upset occurs. Ascorbic acid may interfere with certain laboratory tests (e.g., fecal occult blood, serum creatinine, urinary glucose). Store away from light, moisture, and heat to prevent degradation.
Contraindications
Hypersensitivity to ascorbic acid or any component of the formulation. Contraindicated in patients with a history of oxalate nephrolithiasis or severe renal impairment. Use with caution in individuals with iron overload disorders (e.g., hemochromatosis, thalassemia).
Possible side effect
Generally well-tolerated at recommended doses. High doses (>2000 mg/day) may cause gastrointestinal disturbances such as diarrhea, nausea, abdominal cramps, or flatulence. Rarely, oxalate stone formation may occur in predisposed individuals. Very high doses have been associated with acidification of urine and potential transient osmotic diuresis.
Drug interaction
May increase aluminum absorption from aluminum-containing compounds (e.g., antacids, phosphate binders); separate administration by at least 2 hours. Can increase estrogen levels when taken with oral contraceptives or hormone replacement therapy. May reduce the anticoagulant effect of warfarin; monitor INR closely. Concurrent use with deferoxamine may increase iron toxicity. May alter blood levels of fluphenazine and indinavir.
Missed dose
If a dose is missed, take it as soon as remembered. If it is near the time of the next dose, skip the missed dose and resume the usual dosing schedule. Do not double the dose to catch up.
Overdose
Acute overdose is unlikely to cause serious harm due to the water-soluble nature of ascorbic acid. Extremely high doses may cause pronounced gastrointestinal distress, including severe diarrhea and abdominal pain. Management is supportive; discontinue use and ensure hydration. In cases of accidental ingestion of very large quantities, seek medical attention.
Storage
Store in a tightly sealed container, protected from light, moisture, and oxygen. Keep at room temperature (15–30°C). Do not refrigerate. Once opened, use within 6 months for optimal potency. Keep out of reach of children.

Reviews
“As a clinician, I recommend pure ascorbic acid for its predictable pharmacokinetics and clinical efficacy. Patients with recurrent infections and low plasma vitamin C levels show marked improvement with structured supplementation.” — Dr. Elena M., MD, Integrative Medicine
“I’ve used this in my practice for years. The purity is evident—no fillers, no unnecessary compounds. Ideal for IV formulation under sterile conditions.” — James K., Pharmacist
“Switched from buffered C to pure ascorbic acid and noticed better absorption, less bloating. I use it daily in my antioxidant protocol.” — Maria T., Nutritionist
“Excellent for compounding personalized nutrient formulations. Consistent quality and solubility.” — David L., Clinical Researcher
“I rely on this form for its research-backed bioavailability. A cornerstone of antioxidant support.” — Linda R., PhD, Biochemistry
