Vitamin C Powder (99.99%) from Care and Cure Natraceuticals is pharmaceutical-grade ascorbic acid in unflavoured powder form — delivering pure Vitamin C at 99.99% purity with no additives, fillers, binders, flavourings, or excipients of any kind. Each 200g tub provides approximately 200,000 mg of pure ascorbic acid — a flexible, cost-effective supply that gives you complete control over daily dose without the fixed-amount constraints of capsule or tablet formats.
Ascorbic acid is the biologically active form of Vitamin C — the form present in food, the form circulating in plasma, and the form that participates directly in the enzymatic reactions that Vitamin C is required for. At 99.99% purity, this powder is indistinguishable in biological activity from the highest-grade pharmaceutical ascorbic acid available. It dissolves quickly and completely in water, juice, or other beverages, and is entirely unflavoured — adding a clean, mild tartness when dissolved that many users find pleasant rather than unpleasant.
Vitamin C insufficiency — below the plasma saturation level that optimises immune and antioxidant function — is far more common than clinical deficiency. Powder format is particularly well suited to the following:
- Adults seeking higher daily doses than standard capsules or tablets deliver economically — particularly those targeting 2,000 mg or more per day
- Adults looking to support immune function at higher daily intakes than standard capsules or tablets deliver economically, particularly during autumn and winter months
- Smokers — who deplete Vitamin C significantly faster than non-smokers and require higher daily intake to maintain equivalent plasma levels
- Adults with high physical or metabolic demands — athletes, those with physically demanding routines, or people under sustained psychological stress, all of whom have elevated daily Vitamin C requirements
- Anyone supporting collagen synthesis — for skin health, joint integrity, wound healing, or connective tissue recovery
- People who prefer powder format for ease of mixing into drinks or food, or who have difficulty swallowing capsules
- Those seeking the most cost-effective format for consistent long-term Vitamin C supplementation at meaningful doses
Ascorbic acid’s biological activity spans multiple essential physiological systems simultaneously. This is not a nutrient with a single mechanism — it is a cofactor, antioxidant, and enzyme substrate that the body cannot function at full capacity without.
Immune cell function is directly dependent on Vitamin C at every level — Vitamin C contributes to the normal function of the immune system — one of the most well-established roles of this essential nutrient, and a key reason why consistent daily intake is important throughout the year, and particularly during the colder months when immune demands increase.
Collagen synthesis cannot proceed without Vitamin C — Vitamin C is the essential cofactor for prolyl hydroxylase and lysyl hydroxylase — the enzymes that hydroxylate proline and lysine residues in procollagen, a modification required for the triple-helix structure that gives mature collagen its tensile strength. Without adequate Vitamin C, collagen molecules cannot form properly, and connective tissue — including skin, blood vessel walls, cartilage, tendons, bone matrix, and the walls of the gastrointestinal tract — progressively weakens. Vitamin C contributes to normal collagen formation for the normal function of skin, blood vessels, bones, and cartilage — making consistent intake important for connective tissue across the body.
Vitamin C is the body’s primary water-soluble antioxidant — In plasma and intracellular fluid, Vitamin C is the first line of antioxidant defence — directly scavenging superoxide, hydroxyl radicals, and singlet oxygen before they reach lipid membranes and DNA. After neutralising a free radical, Vitamin C can be regenerated by glutathione and other cellular reducing systems — making it a recyclable antioxidant rather than a single-use sacrificial molecule. This recycling capacity means that adequate Vitamin C status supports the entire antioxidant network, not just its own direct activity — including the regeneration of Vitamin E after lipid-soluble antioxidant reactions.
Iron absorption from plant sources depends on Vitamin C — Non-haem iron — the form found in plant foods including leafy greens, legumes, and fortified cereals — is absorbed significantly less efficiently than haem iron from meat. Vitamin C consumed at the same meal converts non-haem ferric iron (Fe³⁺) to the ferrous form (Fe²⁺) that intestinal transporters preferentially absorb, and forms an iron-ascorbate complex that resists the inhibitory effects of phytates and polyphenols. For vegetarians, vegans, and anyone at risk of iron insufficiency, consistent Vitamin C intake at meals substantially improves iron bioavailability from food.
99.99% purity means no excipients, no fillers, no dose dilution — Standard Vitamin C capsules and tablets contain binders, fillers, anti-caking agents, and coating materials that make up a significant fraction of the tablet weight. At 99.99% purity, this powder is essentially entirely ascorbic acid — every gram you measure is a gram of active Vitamin C. There is no dose uncertainty, no excipient load, and no flavouring that might interact with other supplements or medications. This is the purest, most controllable, and most cost-effective format for serious Vitamin C supplementation.
Powder format enables the flexible dosing that therapeutic Vitamin C requires — The optimal daily dose of Vitamin C varies significantly based on individual circumstances. Baseline plasma saturation in a healthy non-smoking adult requires approximately 200–400 mg per day — achievable through diet plus a modest supplement. During acute infection, physical trauma, or high oxidative stress, requirements increase dramatically — with professional protocols using 1,000 mg to several grams per day in divided doses. Powder format allows you to match your dose to your circumstances without changing products, wasting capsules, or paying premium prices per gram for convenience formats.
99.99% pure ascorbic acid — pharmaceutical/food grade, no additives of any kind
Dosage should be determined by your healthcare professional or qualified nutritionist based on your individual health circumstances. As a general reference, many adults use 500 mg to 2,000 mg per day in divided doses for maintenance and general immune support — but therapeutic protocols may differ significantly.
To measure: use a calibrated digital scale or a standardised measuring spoon. One level teaspoon of ascorbic acid powder is approximately 4,000–5,000 mg — significantly more than a daily maintenance dose. A small kitchen scale accurate to 0.1g is the most reliable measuring tool for precise dosing.
Dissolve the measured amount in a glass of water or juice. The powder dissolves quickly and produces a mildly tart solution. Take with or after meals to reduce gastric sensitivity. Rinse your mouth with plain water after consuming to protect tooth enamel from prolonged acid contact.
Store in a cool, dry place away from direct sunlight and moisture. Keep out of reach of children. Seal tightly after use to prevent moisture absorption, which can cause clumping.
Dosage guidance: Please consult your healthcare professional or nutritionist for appropriate dosage. High-dose Vitamin C (above 2,000 mg per day) may cause loose stools in some individuals — reduce dose if this occurs. People with a history of kidney stones (particularly oxalate stones) should consult their doctor before using high-dose Vitamin C supplementation.
Tooth enamel: Dissolve in a full glass of water and rinse mouth with plain water after consuming. Do not brush teeth immediately after consumption.

FAQs About Vitamin C Powder (99.99%)
Yes. Ascorbic acid is the chemical name for Vitamin C u2014 the same molecule present in food sources of Vitamin C and the same form that circulates in plasma and is used in enzymatic reactions throughout the body. Some Vitamin C supplements use buffered forms such as sodium ascorbate or calcium ascorbate, which are less acidic and may be gentler on the stomach at high doses. Pure ascorbic acid powder is the most concentrated and cost-effective form, providing the same biological activity at a lower cost per gram than buffered alternatives.
Dosage depends on your individual health circumstances and should be confirmed with your healthcare professional or nutritionist. As a general reference: the UK recommended daily intake is 40 mg the minimum to prevent deficiency. Plasma saturation (the level at which immune cells are fully loaded) requires approximately 400 mg per day. Many adults use 500 mg to 2,000 mg per day in divided doses for general immune and antioxidant support. Higher-dose protocols u2014 for periods of increased demand, such as sustained high physical activity u2014 may be used under the guidance of a healthcare professionalAlways divide your daily dose into two or three servings for more stable plasma levels.
Powder format offers complete dose flexibility, significantly lower cost per gram of active Vitamin C, and no excipient load. Capsules and tablets contain binders, fillers, coating agents, and anti-caking materials that dilute the active ingredient and add cost. At 99.99% purity, this powder is essentially entirely ascorbic acid u2014 every gram measured is a gram of active Vitamin C. Powder also allows you to precisely increase or decrease your dose based on circumstances without changing products or wasting fixed-dose capsules.
A calibrated digital kitchen scale accurate to 0.1g is the most reliable tool u2014 volume measures like teaspoons are inconsistent because powder density varies. As a rough reference, 1g (1,000 mg) of ascorbic acid powder is approximately a quarter teaspoon. For consistent therapeutic dosing, weigh each serving rather than using volume measures. Dissolve the weighed amount in a full glass of water before consuming.
People with a history of calcium oxalate kidney stones are sometimes advised to moderate high-dose Vitamin C intake, as ascorbic acid is partially metabolised to oxalate. For most adults without a history of oxalate stones, the evidence that high-dose Vitamin C supplementation meaningfully increases kidney stone risk is not strong. If you have a history of kidney stones or are at elevated risk, consult your GP before using high-dose Vitamin C supplementation. Adequate hydration is important for anyone supplementing at higher doses.
At doses that exceed the gutu2019s absorption capacity, unabsorbed ascorbic acid draws water into the large intestine through osmosis, causing loose stools u2014 a phenomenon called bowel tolerance. The dose at which this occurs varies significantly between individuals and increases during illness when the bodyu2019s demand for Vitamin C is elevated. Divided dosing u2014 spreading your total daily amount across two or three servings u2014 raises the effective threshold. If loose stools occur, reduce each serving amount and distribute more frequently.
Yes. Ascorbic acid powder at 99.99% purity contains no animal-derived ingredients. It is suitable for vegetarians and vegans. The product contains no excipients, binders, or additives of any kind u2014 it is pure ascorbic acid.
