Fruits And Vegetables With High Levels Of Vitamin C
There are many fruits and vegetables that have high levels of Vitamin C. If youre worried about taking supplements and the side effects, eating fruit ensures you get your daily dose of Vitamin C without the problems.
Guava has 377 milligrams of Vitamin C. Kiwis have 167 mg.
Bell peppers have 190 milligrams per cup and only 46 calories. Berries like blueberries, blackberries, raspberries, and strawberries all contain Vitamin C. Strawberries contain the highest amount at 98 mg per cup.
Surprisingly, oranges, often synonymous with high amounts of Vitamin C have only 96 mg per cup. Clementines, lemons, and grapefruits are also good sources of Vitamin C but contain fewer milligrams than oranges.
Broccoli, cabbage, and Brussel sprouts are also good sources of Vitamin C. Kale is also a good source with 53 mg per cooked cup.
With so many choices, its easy to start your day with a healthy breakfast that contains enough Vitamin C to keep you healthy.
What Is Vitamin C
High dose vitamin C may especially be useful if your body is under more than usual amounts of stress or you are feeling excessive fatigue. The immune system benefits form the presence of Vitamin C in your system in fighting acute or chronic viral and bacterial infections. Vitamin C can also be used as post-surgical care or to treat skin damage caused by the sun.
High dose vitamin C is also a traditional anti-cancer treatment and may also help improve the side effects of conventional cancer treatment such as chemotherapy and radiation therapy like fatigue, nausea and vomiting. In our cancer program Vitamin C is also combined with Amygdalin and DMSO.
Recently conducted research indicated that vitamin C in pharmacologic concentrations killed cancer cells but not normal cells. The mechanism works via hydrogen peroxide formation which causes cancer cell death.
Excessive Intake Of Vitamin C Can Produce Negative Interactions
Taking a Vitamin C supplement in a higher dosage than whats recommended can have adverse interactions, especially if youre on certain medications.
Some medicines contain aluminum such as phosphate binders. Taking more than 2,000 mg in supplement form can increase your absorption of aluminum. This can be harmful to people suffering from kidney problems.
If youre taking an oral contraceptive or are on a hormone replacement therapy, taking an excess of Vitamin C in supplement form may increase your estrogen levels.
Talk to your doctor if youre on chemotherapy. Using antioxidants like Vitamin C while undergoing chemotherapy may reduce the drugs effects. However, speak with your physician first as there is a difference in opinion on antioxidants and its effects on chemotherapy.
Taking Vitamin C orally in supplement form may reduce the effects of protease inhibitors. And if youre taking Vitamin C with niacin, Warfarin, Coumadin or Jantoven, it may reduce the effects the prescribed drug is supposed to have on your body.

Why Is Vitamin C Important For My Health
Vitamin C has many important functions in the body, including keeping your skin, bones and connective tissue healthy as well as help your body absorb iron. Some people incorrectly believe vitamin C will help prevent you from catching the common cold. While there have been many attempts to support this idea with research-based evidence, there is still no convincing proof of a significant benefit. A high dose of vitamin C taken as soon as you get symptoms may, however, lessen the duration of a cold.
A major vitamin C deficiency can lead to scurvy. This condition can involve bone and blood vessel disease, bleeding, pain in the hands and feet, and in extreme cases, death.
Is Colon Hydrotherapy Safe
Being an essentially natural and gentle process, there is virtually no danger with a colonic treatment. The treatment is always accompanied by a trained specialist. There may be initial discomfort due to the pressure and occasional cramping of the intestinal muscles, but this all is kept to a minimum and will reside once you get used to the process. Many patients report about a very pleasant experience after an initial adjustment phase.

Watch Out For These Fat
Here are details about vitamins A, E and K and the symptoms of overdose to look out for.
Vitamin A is a fat-soluble nutrient that is naturally present in many foods, like beef, eggs and many fruits and vegetables. An overdose of this vitamin can lead to problems with confusion, hair loss, liver damage and bone loss. It can also cause an increased risk for death and lung-associated issues for those who have a history of smokingparticularly female smokers.
Vitamin E is a fat-soluble nutrient found naturally in foods and added to some fortified foods that can help protect cells from damage caused by free radicals, such as air pollution. But taking too much of this supplement can increase your risk for bleeding and bleeding in the brain.
Vitamin K is a fat-soluble nutrient thats important for blood clotting, healthy bones and other bodily functions. Its rare that youll overdose on vitamin K by eating things like broccoli. But in supplement form, it can induce blood clots, which can lead to heart attacks and strokes, if you take too much.
Risks And Adverse Events
Adverse events related to HDIVC included nausea or vomiting during or after infusion of VC electrolyte disturbance and acute kidney injury, as described by Khoshnam-Rad . AEs and serious adverse events were observed and followed in accordance with the good clinical practice guidelines issued by the National Medical Products Administration of the Peoples Republic of China. If any severe adverse events were observed during infusion, the infusion was stopped immediately, and the patients vital signs were carefully monitored. All the AEs and SAEs were recorded in detail, and the causal relationship between the infusion and AEs was analyzed.

Clinical Studies On Ivc In Combination Treatments
Most of the clinical studies presented in this section dose-escalated VitC to achieve â¥20âmM plasma ascorbate concentrations. In general, this was achieved when administering 75âg infusions at least 3 times weekly, and was not significantly further increased at 100âg or more . For those studies administering per kg of body weight, amounts â¥1.0âg VitC/kg were needed to achieve plasma levels of at least 20âmM. We focus in detail only on those studies administering â¥1.0âg/kg orââ¥â75âg andââ¥â10âg whole body dose .
Clinical studies combining chemotherapy and radiation therapy
Consistent with positive data obtained from animal and other pre-clinical studies, several of these phase I/II studies reported trends towards increased disease control and objective response rates, although all were underpowered for detection of efficacy. In the randomized trial of Ma et al. in ovarian cancer , the median time for disease progression was 8.75âmonths longer with ascorbate addition to standard chemotherapy than in chemotherapy alone. Single group studies showed favourable OS and PFS compared to historical controls and institutional averages .
Clinical studies using VitC in combination with targeted therapy
While all these completed trials studied combinations of chemo- and targeted therapies only, 3 ongoing trials are now investigating the addition of IVC to targeted agents only .
Intravenous Vitamin C And Cancer
Studies on dose-concentration relationship in humans, performed by Levine and co-workers , revealed that at oral doses exceeding 250 mg/day, the plasma levels of Vitamin C reach a plateau, and any further increase in the amount administered by mouth, does not determine significant increase in plasma concentration. This is due to multiple control mechanisms, including, among others, intestinal absorption, tissue accumulation, renal reabsorption and excretion, and utilization. On the contrary, the intravenous administration of high doses of Vitamin C, bypassing the above control mechanisms, allows plasma concentrations that are 100-fold or higher than maximally tolerated oral doses, and the peak could last for hours within the millimolar range .
More recently, Yun and co-workers , by investigating the effects of high doses of Vitamin C on KRAS and BRAF mutants cells derived from colorectal cancer , have further refined the mechanistic explanation of the anticancer properties of Vitamin C. In particular, according to the authors, the death of KRAS and BRAF cell mutants of CRC is not caused by the Vitamin C itself, but rather, by its oxidized form, dehydroascorbic acid . While Vitamin C enter cells though specific receptors, called sodium-Vitamin C co-transporters , DHAA competes with glucose, for intracellular uptake by glucose transporters , mainly 1 and 4 subtype receptors .

How To Take It
The best way to take vitamin C supplements is 2 – 3 times per day, with meals, depending on the dosage. Some studies suggest that adults should take 250 – 500 mg twice a day for any benefit. Talk to your doctor before taking more than 1,000 mg of vitamin C on a daily basis and before giving vitamin C to a child.
Daily intake of dietary vitamin C is listed below.
Pediatric
- Men over 18 years: 90 mg
- Women over 18 years: 75 mg
- Pregnant women 14 – 18 years: 80 mg
- Pregnant women over 18 years: 85 mg
- Breastfeeding women 14 – 18 years: 115 mg
- Breastfeeding women over 18 years: 120 mg
Because smoking depletes vitamin C, people who smoke may need an additional 35 mg per day.
The dose recommended to prevent or treat many of the conditions mentioned in the Uses section is often 500 – 1,000 mg per day.
The Hif Pathway In Leukemia
The role of HIF-1 in leukemia, and in particular in acute myeloid leukemia , has only recently emerged and it is still somewhat controversial. One possible explanation for this delayed interest in the role of hypoxia in leukemia could be the fact that leukemia is not considered a solid tumor, and therefore, the role of oxygen, in its pathogenesis, has been considered inconsequential for long time. This erroneous view, has been recently reviewed, as data have emerged, demonstrating that leukemic cells are sensitive to the oxygen tension, and hypoxia influences leukemic cell proliferation, differentiation, and resistance to chemotherapy .
Migliavacca and Coll. have recently demonstrated oncogenic function of HIF-1, in the M5 Fab subtype of AML . In particular, the authors have demonstrated that in M5 AML, HIF-1 mediates the ability of leukemic cells to migrate and invade extramedullary sites. The same group has demonstrated that PML-RAR and other fusion proteins involved in the pathogenesis of acute promyelocytic leukemia behave as transcriptional coactivators of HIFs, and both HIFs and PML-RAR enhances the progression of APL, by promoting cell migration, homing to bone marrow, and bone marrow neo-angiogenesis .
Further investigations have demonstrated that HIF-1 plays critical and pleiotropic roles in the pathogenesis of chronic lymphocytic leukemia .

Latest Evidence Of The Role Of Vitamin C In Leukemia
A recent study provided clear-cut evidence that Vitamin C is a main regulator of hematopoietic stem cell function and leukemogenesis. In fact, Agathocleous and co-workers, using a peculiar strategy for isolation of HSCs and hematopoietic progenitor cells from murine bone marrow, showed that HSCs have unusually high levels of Vitamin C, which decline with differentiation . Importantly, human HSCs and multipotent progenitor cells , such as murine HSCs, display high Vitamin C levels.
Using GULO mice , Agathocleous and colleagues have shown that Vitamin C deficiency induces an increased number of HSCs. A FLT3-internal tandem duplication mutation, found in approximately a quarter of patients with de novo AML, imparts a particularly poor prognosis. Using GULO mice , Agathocleous and colleagues have shown that Vitamin C deficiency induces an increased number of HSCs. Therefore Vitamin C deficiency, and TET2 mutations, are likely to cooperates with FLT3-ITD to induce leukemia development in murine models of FLT3-ITD-driven leukemia. .

Do Colonics Wash Out Valuable Intestinal Flora And Nutrients
The important bowel bacteria are present on the bowel wall and are not removed during Colonic Irrigation treatment, thus leaving a large nucleus to grow naturally. Good microbiota can only breed in a balanced environment. Also, valuable nutrients may be better absorbed in a clean environment than in a putrefied one.
Drop In Vitamin C Levels
The team pointed out that vitamin C levels can drop in patients with acute respiratory infections, giving cause to top up levels, irrespective of the vitamins influence an observation also noted by Dr Weber.
Vitamin C levels in coronavirus patients drop dramatically when they suffer sepsis, an inflammatory response that occurs when their bodies overreact to the infection, he said. It makes all the sense in the world to try and maintain this level of vitamin C.
At least three clinical trials have started in China studying the effects of high-dose IV vitamin C for the treatment of COVID-19 with one beginning as recently as 14 February.
In addition, the Shanghai Medical Association released the first and only official government guideline on March 1 for the treatment of COVID-19 where high-dose IV vitamin C was endorsed by experts.
Its publication may have played a part in an explosion of vitamin C supplement sales in the country, where Chinese e-commerce giant, JD reported a five-fold increase in consumer purchases.
Sales of health products including vitamin C effervescent tablets, Traditional Chinese Medicine brand Banlangen, and Xiao Chaihu saw big increases.
JD said the virus outbreak was the cause of the surge consumption, and its higher online sales was attributed to consumers preferring to order delivery online instead of going to supermarket to purchase products.

How Will I Know When The Colon Is Empty
Your colon will probably never be completely empty, as it is an organ in continuous use. With the treatment we only treat the lower part of your large intestines. As treatment s progress we may reach the upper part of your large intestines as well. This will have a synergistic effect on your intestinal system and we will indirectly treat you complete colon. The objective should not be an empty colon, but rather a well-functioning colon.
Randomization Allocation And Blinding
Each ICU was assigned with an independent random numeric table generated by Microsoft Excel 2019 by the primary investigator alone. Each table had equal numbers of 1 and 2, which represented the placebo group and treatment group , respectively. The generated random list was stored by the principal investigator who was not involved in the treatment of patients and hidden to the other investigators. When a patient was transferred to the ICU and met the enrollment criteria, the clinician on duty would inform the principal investigator and obtain a number from the list. Then, participants were enrolled in the corresponding group according to the chronological order of ICU recruitment. The grouping and intervention were unknown to the participants and investigators who were responsible for data collection and statistical analysis. VC injection and sterile water for injection were both colorless and contained in the same brown syringes with different marks and without explanations on the syringe to make sure that patients could not distinguish the treatment they receive.

What Drugs Interact With High
A drug interaction is a change in the way a drug acts in the body when taken with certain other drugs. High-dose vitamin C, when combined with some anticancer drugs, may cause them to be less effective. So far, these effects have been seen only in some laboratory and animal studies. No clinical trials have been done to further research these drug interactions in humans.
- Combining vitamin C with an anticancer drug called bortezomib has been studied in cell cultures and in animal models. Bortezomib is a targeted therapy that blocks several molecular pathways in a cell, causing cancer cells to die. Several studies showed that vitamin C given by mouth made bortezomib less effective, including in multiple myeloma cells. A study in mice transplanted with human prostate cancer cells, however, did not show that giving the mice different doses of vitamin C by mouth made bortezomib therapy less effective.
- An oxidized form of vitamin C called dehydroascorbic acid has been studied in cell cultures and in animals with tumors. Several studies have found that high doses of dehydroascorbic acid can interfere with the anticancer effects of several chemotherapy drugs. Dehydroascorbic acid is found in only small amounts in dietary supplements and in fresh foods.
