Many cancer patients on intensive chemotherapy lack vitamin C. Vitamin C stimulates the production and activation of immune cells, so perhaps supplementation could be used to improve the immunity in those patients.

The Effect of Intravenous Vitamin C on Cancer- and Chemotherapy-Related Fatigue and Quality of Life

Vitamin C is an antioxidant that may scavenge reactive oxygen species preventing DNA damage and other effects important in cancer transformation. Dietary vitamin C from natural sources is taken with other compounds affecting its bioavailability and biological effects. High pharmacological doses of vitamin C may induce prooxidant effects, detrimental for cancer cells. An oxidized form of vitamin C, dehydroascorbate, is transported through glucose transporters, and cancer cells switch from oxidative phosphorylation to glycolysis in energy production so an excess of vitamin C may limit glucose transport and ATP production resulting in energetic crisis and cell death. Vitamin C may change the metabolomic and epigenetic profiles of cancer cells, and activation of ten-eleven translocation TET proteins and downregulation of pluripotency factors by the vitamin may eradicate cancer stem cells.

Vitamin C L-ascorbic acid is a potent reducing agent, meaning that it readily donates electrons to recipient molecules Figure 1. Vitamin C is the primary water-soluble, non-enzymatic antioxidant in plasma and tissues. Even in small amounts, vitamin C can protect indispensable molecules in the body, such as proteins , lipids fats , carbohydrates , and nucleic acids DNA and RNA , from damage by free radicals and reactive oxygen species ROS that are generated during normal metabolism , by active immune cells, and through exposure to toxins and pollutants e. Vitamin C also participates in redox recycling of other important antioxidants; for example, vitamin C is known to regenerate vitamin E from its oxidized form see the article on Vitamin E. The role of vitamin C as a cofactor is also related to its redox potential. By maintaining enzyme-bound metals in their reduced forms, vitamin C assists mixed-function oxidases in the synthesis of several critical biomolecules 1. These enzymes are either monooxygenases or dioxygenases see Table 1.

Intravenous Ascorbic Acid also known as vitamin C or L-ascorbic acid , is a type of therapy that delivers soluble ascorbic acid directly into the bloodstream, either administered via injection or infusion. Intravenous ascorbic acid is used as a dietary supplement for nutritional deficiencies and also, as complementary therapy to cancer treatments. The use of intravenous ascorbic acid as a cancer treatment or co-treatment has been a controversial topic since the emergence of misleading data in the s. In patients suffering from malnutrition or malabsorption , intravenous ascorbic acid can be used to treat deficiency. For people who are receiving all of their nutrient requirements via total parenteral nutrition there are vitamin products that include ascorbic acid. High doses of ascorbic acid administered by intravenous infusion have been shown to increase the absorption of iron. High dosages of ascorbic acid such as those used in intravenous therapy have been reported to cause some intestinal discomfort, diarrhoea, as well as increased gas and urination.

The use of intravenous vitamin C IVC for cancer therapy has long been an area of intense controversy. Despite this, high dose IVC has been administered for decades by complementary health care practitioners and physicians, with little evidence base resulting in inconsistent clinical practice. In this review we pose a series of questions of relevance to both researchers and clinicians, and also patients themselves, in order to identify current gaps in our knowledge. These questions include: Do oncology patients have compromised vitamin C status? Is intravenous the optimal route of vitamin C administration?


Background. Intravenous vitamin C (IVC) is a contentious adjunctive cancer therapy, widely used in naturopathic and integrative oncology.

Беккер шумно вздохнул и поднял глаза к потолку. Успокойся, Дэвид. Спокойно.

Снова воцарилось молчание. Стратмор покачал головой, отказываясь верить тому, что услышал.

Intravenous Vitamin C for Cancer Therapy – Identifying the Current Gaps in Our Knowledge

Скажи. Сьюзан словно отключилась от Хейла и всего окружающего ее хаоса. Энсей Танкадо - это Северная Дакота… Сьюзан попыталась расставить все фрагменты имеющейся у нее информации по своим местам. Если Танкадо - Северная Дакота, выходит, он посылал электронную почту самому себе… а это значит, что никакой Северной Дакоты не существует.

Из пулевого отверстия в виске хлестала кровь - прямо на. Росио попробовала закричать, но в легких не было воздуха. Он вот-вот задавит .

Чудесным образом Северная Дакота обнаружился прямо под носом и теперь попал в западню. Правда, оставалась еще одна проблема - Дэвид до сих пор не нашел второй экземпляр ключа. Она молилась, чтобы его усилия увенчались успехом. Направляясь к центру Третьего узла, Сьюзан пыталась привести свои мысли в порядок. Странно, что она чувствует нервозность в такой знакомой ей обстановке.

Ему вдруг страшно захотелось увидеть ее - сейчас. Прохладный ветерок кондиционера напомнил ему о жаре на улице. Он представил себе, как бредет, обливаясь потом, по душным, пропитанным запахом наркотиков улицам Трианы, пытаясь разыскать девчонку-панка в майке с британским флагом на груди, и снова подумал о Сьюзан. - Zumo de arandano, - с удивлением услышал он собственный голос.

Ничего похожего. У Халохота был компьютер Монокль, мы и его проверили. Похоже, он не передал ничего хотя бы отдаленно похожего на набор букв и цифр - только список тех, кого ликвидировал. - Черт возьми! - не сдержался Фонтейн, теряя самообладание.

В трубке повисло молчание. - Мидж… - Джабба попробовал извиниться.  - Позволь мне объяснить.  - Голос его, однако, мягче не.  - Во-первых, у нас есть фильтр, именуемый Сквозь строй, - он не пропустит ни один вирус.

 Надо вырубить все электроснабжение, и как можно скорее! - потребовала Сьюзан.

Background: Ascorbate vitamin C has been evaluated as a potential treatment for cancer as an independent agent and in combination with standard chemotherapies.
