Vitamin C and immune function: a review of the evidence
Nutrients, 2017
Each capsule delivers 1000mg of Vitamin C (ascorbic acid) using a time-release matrix that gradually releases the dose over several hours rather than all at once. Sustained release maintains more consistent blood levels of Vitamin C throughout the day, reduces urinary excretion of excess Vitamin C, and may be gentler on the stomach than immediate release high-dose Vitamin C. Supports immune function, antioxidant protection, and collagen synthesis.
Vitamin C (ascorbic acid) used in supplements is produced by fermentation of glucose, typically derived from corn or other plant-based carbohydrate sources, followed by chemical conversion to ascorbic acid. The resulting ascorbic acid is chemically identical to the Vitamin C found naturally in fruits and vegetables. The time-release matrix uses hydroxypropyl methylcellulose (HPMC), a plant-derived polymer widely used in pharmaceutical and supplement manufacturing.
Vitamin C is a water-soluble vitamin that the body cannot produce or store. At high doses, intestinal absorption becomes saturated and excess Vitamin C is rapidly excreted in urine, meaning a large immediate-release dose may result in significant urinary loss before it can be absorbed. Time-release delivery gradually releases Vitamin C over several hours, maintaining more consistent blood levels, reducing the peak concentration that triggers urinary excretion, and providing sustained support throughout the day from a single capsule. The gradual release also reduces the likelihood of digestive discomfort that some individuals experience with immediate-release high-dose Vitamin C.
Non-medicinal ingredients: Hypromellose (vegan capsule), hydroxypropyl methylcellulose (time-release matrix), microcrystalline cellulose, magnesium stearate (vegetable source). Non-GMO, gluten free, soy free, dairy free. No artificial colours, flavours, sweeteners, or preservatives.
Adults: Take 1 capsule once per day with food. Taking with food may further reduce the likelihood of digestive discomfort. The time-release formula provides sustained support throughout the day from a single daily capsule. Vitamin C is water-soluble and not stored in the body, making consistent daily use important.
Store in a cool, dry place away from direct sunlight and moisture. Keep the bottle tightly sealed after each use. Keep out of reach of children.
Consult a healthcare practitioner before use if you are pregnant or breastfeeding, taking medications, or have kidney disease, kidney stones, or iron overload disorders. High-dose Vitamin C may cause digestive discomfort in some individuals. Vitamin C may interact with certain medications including chemotherapy drugs and statins. The tolerable upper intake level for Vitamin C is 2000mg per day for adults. Keep out of reach of children.
