Vitamin C Improves Endothelium-Dependent Vasodilation by Restoring Nitric Oxide Activit... - 0 views

  •  
    IV Vitamin C improves endothelial vasodilation in essential hypertension.  The Vitamin C reduces the oxygen free radicals which allowed eNOS to increase NO production.  Two take homes: oxygen free radicals may be responsible for the endothelial dysfunction that leads to essential hypertension and vitamin C, particularly IV, can be used to counter this process.  Other studies have shown IV vitamin C to be anti-hypertensive in its action.

A Vitamin B-12 Supplement of 500 μg/d for Eight Weeks Does Not Normalize Urin... - 0 views

  •  
    current vitamin B12 recommendations are too low.  Proper vitamin B12 biomarker testing reveals this fact. The problem is most people fall prey to the lack of knowledge behind simple serum levels.  Simple B12 serum levels are woefully inadequate. Insurance would rather one stay with inadequate testing to save money, rather than actually read the science to learn about new testing.

Meta-analysis of Vitamin D Sufficiency for Improving Survival of Patients with Breast C... - 0 views

  • Higher serum 25(OH)D concentrations were associated with lower fatality rates in patients with breast cancer
  • Patients with the highest concentration of 25(OH)D had approximately half the fatality rate compared to those with the lowest concentration
  • According to this hypothesis, the growth of a tumor may be arrested at almost any point in the DINOMIT model by restoring a high serum 25(OH)D concentration in the organism, resulting in up-regulation of E-cadherin and restoration of a well-differentiated state

  • Laboratory studies have demonstrated anticancer effects of vitamin D metabolites on three critical phases in the development of breast tumors: differentiation, apoptosis, and angiogenesis
  •  
    Higher vitamin D levels associated with lower death rates from breast cancer.  In fact, people with the highest levels of vitamin D had death rates cut in half.  The authors point to 3 ares that vitamin D has a positive effect against cancer: differentiation, apoptosis, and angiogenesis.

High-dose vitamin C therapy for inclusion body myositis. - PubMed - NCBI - 0 views

  •  
    study finds "high dose" IV vitamin C benefited 3 of 5 patients in short 4 week study.  The "high dose" was not high dose at all, so that fact that a low dose of IV vitamin C will benefit dermatomysotis in over 50% of the patients in this very small study points to the question, what if actually high dose vitamin C is used.

Intravenously administered vitamin C as cancer therapy: three cases - 0 views

  • peak plasma concentrations obtained intravenously are estimated to reach 14 000 μmol/L, and concentrations above 2000 μmol/L may persist for several hours
  • Emerging in vitro data show that extracellular ascorbic acid selectively kills some cancer but no normal cells by generating hydrogen peroxide
  • Death is mediated exclusively by extracellular ascorbate, at pharmacologic concentrations that can be achieved only by intravenous administration
  • ...6 more annotations...
  • Vitamin C may serve as a pro-drug for hydrogen peroxide delivery to extravascular tissues, but without the presence of hydrogen peroxide in blood
  • not all cancer cells were killed by ascorbic acid in vitro
  • Intravascular hemolysis was reported after massive vitamin C administration in people with glucose-6-phosphate dehydrogenase deficiency
  • Administration of high-dose vitamin C to patients with systemic iron overload may increase iron absorption and represents a contraindication
  • Ascorbic acid is metabolized to oxalate, and 2 cases of acute oxalate nephropathy were reported in patients with pre-existing renal insufficiency given massive intravenous doses of vitamin C
  • Rare cases of acute tumour hemorrhage and necrosis were reported in patients with advanced cancer within a few days of starting high-dose intravenous vitamin C therapy, although this was not independently verified by pathologic review
  •  
    IV vitamin C associated with prolonged survival in 3 patients with different cancers.  Peak serum levels reached 14,000 micromol/L, which levels above the 1,000 micro mol/L (cancer cell cytotoxic threshold) were maintained for hours

Vitamin C Pharmacokinetics: Implications for Oral and Intravenous Use | Annals of Inter... - 0 views

  •  
    IV vitamin C found to significantly increased serum levels beyond that of oral.  IV vitamin C is the only route that should be administered for patients with cancer.  IVC at 50 grams showed peak C concentration at 13,400 micromol/L.  Levels of at least 400-600 are required for tumorcidal effects.  In addition, IV vitamin C increased NO release and decreases b/p

Intravenous Vitamin C and Cancer: A Syste... [Integr Cancer Ther. 2014] - PubMed - NCBI - 1 views

  •  
    So help me out here:  If IV vitamin C has been shown to prolong time to cancer relapse, aid in reducing tumor size, improve survival with chemotherapy, improve quality of life, improve physical function, reduce chemo side effects, improve energy, reduce nausea, aid insomnia, reduce constipation, and improve depression in cancer patient--then why does the author say that IV vitamin C is contentious?  Add that IV vitamin C has not been implicated in any deaths in cancer therapy.  Contrast that with chemotherapy.  Why again is this contentious?  Whom is best served by this being contentious?

Effect of high dose intravenous ascorbic acid on the level of inflammation in patients ... - 0 views

  •  
    This study, small pilot, showed that they were able to lower inflammation in those suffering from RA, through high dose vitamin C IV therapy. This study stopped at 25 gms. The vitamin C is a scavenger of ROS and ROS stimulates inflammation through NF-kappaB. This is how vitamin C can reduce inflammation.

Vitamin Intervention for Stroke Prevention Trial - 0 views

  •  
    Vitamin B12, methyl cobalamin, is very important in lowering homocysteine levels through methionine synthase.  The VISP trial did not show efficacy in the intention to treat analysis.  However, analysis of the efficacy reveals that many clients had too low of vitamin B12 levels due to malabsorption and vitamin B12 levels should have been higher in the VISP intention to treat.

Vitamin C and survival among women with breast cancer: A Meta-analysis - 0 views

  •  
    Meta-analysis finds that for every oral daily intake of 100 mg vitamin C, the risk of total mortality was decreased by 27% and the breast cancer specific mortality was decreased by 22%.  A lot of potential variables that can play into this equation.  However, oral vitamin C is poorly bioavailable, yet according to this meta-analysis, does provide significant health benefits and even prevention.  If health and breast cancer prevention is a goal, then vitamin C needs to play a role in your daily intake.

Converging pathways lead to overproduction of IL-17 in the absence of vitamin D signaling - 0 views

  •  
    Low vitamin D levels or the receptors for vitamin D appear to result in an increase in Th17 cells.  An increase in Th17 cells will lead to an imbalance with Treg cells and this imbalance is associated with Lupus and other autoimmune processes.  Vitamin D inhibits Th17 cell activation.
