Support your immune system & enhance your living quality

Vitamin C

Vitamin C is the most important water-soluble vitamin in the human body, because it is a cofactor for various enzymes, collagen, cholesterol metabolism, and synthesis of neurotransmitters in the body. Vitamin C, also known as Ascorbic Acid, also plays an important role in the function of immune cells.

Most mammals can synthesize vitamin C from their bodies on their own, but humans cannot make it by themselves due to lack of such genes. They must get enough vitamin C from other sources (such as food/nutrition supplements). Due to the instability of vitamin C in food, storage, high temperature or over-cooking will destroy many vitamin C. Eating natural foods alone may not be able to meet daily needs, so some people choose to take vitamin C-rich nutrition supplements, or pursue high dosage vitamin c therapy.

It should be noted that the human body has a very strict regulatory mechanism for the absorption of vitamin C. Therefore, despite the high oral dose of vitamin C, the concentration of vitamin C in the blood is still maintained at tens of micromoles (μmol/L), making it unable to achieve optimal results. In addition, orally intake high-dose vitamin C may cause stomach irritation, nausea, vomiting, abdominal pain and diarrhea and other gastrointestinal symptoms.

High dosage vitamin c therapy drip, which is more common in Europe and the United States, a method that supplements vitamin C through intravenous injection, allowing vitamin C to be taken directly into the blood. This method helps elevate blood concentration of vitamin C to a level that is around 100+ times higher than having oral administration of vitamin C. In addition, this method can bypass the digestive system and avoid gastrointestinal irritation, and there are no obvious side effects. Therefore, some people choose to take high dosage vitamin C through IV drip.

Background of
High Dosage Vitamin C Therapy

As early as half a century ago, vitamin C has been used to prevent common colds and scurvy (Scurvy). Dr. Linus Carl Pauling, an American chemist who won the Nobel Prize twice, discovered that high dosage vitamin c therapy has a supportive effect on the overall cancer treatment plan. He and his team discovered that not only IV Vitamin C drip has the opportunity to enhance the immunity of cancer patients and promote the health of patients, but also may help on their life expectancy. Since then, more laboratory and clinical studies have discovered that applying high dosage vitamin C in cancer treatments has the potential to reduce the division of a variety of cancer cells, reduce cancer recurrence and improve the quality of life of patients (More studies are needed to verify such claims).

Therefore, high dosage vitamin c therapy, in Hong Kong and abroad, has widely been used in integrative therapy.

As A Supportive Therapy

Vitamin C is an antioxidant nutrient that is beneficial to the body. It is originally an essential nutrient for the body to reduce toxins and defend against infections. In addition to the fact that IV Vitamin C Drip can help increase the level of vitamin C in the blood, studies have also discovered that having a corresponding dose of IV Vitamin C has a supportive effect on radiotherapy or chemotherapy.

High dosage vitamin C in cancer treatment, has the potential to (1) reduce the side effect in traditional treatment (including nausea, loss of appetite, fatigue, depression, insomnia, dizziness, low immunity, weakness, etc.), and (2) support cancer patients for a better life quality.

The lung cancer target “Ai XX” claims to have a response rate of about 10%, and the non-deteriorating period after use has been extended from 6.3 months to 9.2 months. “Cancer X Stop” for metastatic colorectal cancer, compared to the chemotherapy-only control group, the non-malignant period is about 0.8 to 4.4 months longer, and for ovarian cancer it is 1.7 months. The non-malignant period of advanced kidney cancer and liver cancer target drug “Lei XX” has been extended from 2.8 months to 5.5 months for advanced kidney cancer, and the non-malignant period for patients with advanced liver cancer has been extended from 1.4 months to 2.8 months. All target drugs will inevitably face the problem of drug resistance quickly after use
