The Effects of Vitamin C on the Multiple Pathophysiological Stages of COVID-19.

Currently available anti-viral drugs may be useful in reducing the viral load but are not providing the necessary physiological effects to reduce the SARS-CoV-2 complications efficiently. Treatments that provide better clinical outcomes are urgently needed. Vitamin C (ascorbic acid, AA) is an essential nutrient with many biological roles that have been proven to play an important part in immune function; it serves as an antioxidant, an anti-viral, and exerts anti-thrombotic effects among many other physiological benefits.

Role of treatment-modifying MTHFR677C>T and 1298A>C polymorphisms in metformin-treated Puerto Rican patients with type-2 diabetes mellitus and peripheral neuropathy.

Background: The study was conducted to investigate potential association between MTHFR genotypes and diabetic peripheral neuropathy (DPN) in Puerto Ricans with type-2 diabetes mellitus (T2DM) treated with metformin. The prevalence of major MTHFR polymorphisms in this cohort was also ascertained.

Methods: DNAs from 89 metformin-treated patients with T2DM and DPN were genotyped using the PCR-based RFLP assay for MTHFR677C>T and 1298A>C polymorphisms.

High dose intravenous vitamin c treatment in a patient with lung cancer: A case report.

Lung cancer is one of the most common cancers in both men and women. According to Dr. Abram Hoffer, patients with a better nutritional plan and daily Vitamin C supplementation improved their life quality.

High Dose Intravenous Vitamin C Treatment for Zika Fever.

The Zika Fever is a viral disease caused by a single-stranded RNA virus from the Flavivirus genus, Flaviviridae family, from the Spondweni group. Its transmission occurs through mosquito vectors, principally Aedes Aegypti. The most common symptoms of Zika are fever, rash, joint pain, and conjunctivitis (red eyes).

Metabolic Correction in Patients Sample with Diabetes: Clinical Outcomes and Costs Reductions.

Diabetes is a leading cause of mortality and morbidity worldwide. Diabetes complications produce profound impact on patient's quality of life and represent very significant economic cost to patients, their family, the government and society as a whole. Metabolic correction has been proposed as an efficient method to improve clinical outcomes and reduce costs in diabetes.

Archaic RDA Methodology for Vitamin C.

Frei et al's 2012 review entitled "Authors' Perspective: What is the Optimum Intake of Vitamin C in Humans" is both flawed and misleading. RCTs are ill suited to determining the RDA, it is debatable that there is sufficient scientific evidence to determine the optimum intake of vitamin C in humans, observations regarding high-doses of ascorbate have been ignored, and there are inaccuracies of fact with respect to the saturation of blood plasma following low dose intake. Until the limitations of current knowledge are recognised it is unwise to set limits on the dose.

[Metabolic correction: a biochemical option against diseases].

Human development and its physiology depends on a number of complex biochemical body processes, many of which are interactive and codependent. The speed and the degree in which many physiological reactions are completed depend on enzyme activity, which in turn depends on the bioavailability of co-factors and micronutrients such as vitamins and minerals. To achieve a healthy physiological state, organism need that biochemical reactions occur in a controlled and specific way at a particular speed and level or grade fully completed.

Metabolic Correction as a tool to improve diabetes type 2 management.

Diabetes Mellitus type 2 (DM2) is a metabolic disease that develops by a decrease in sensitivity of insulin receptors as an effect of the disruption certain metabolic functions in the processing of glucose. DM2 patients have, uncontrolled glucose levels, and commonly have problems with obesity and cardiovascular disease. Patients are treated with standard diet, insulin, diabetic oral agents and antihypertensive drugs, but this approach does not completely stops tissue deterioration since it does not address the metabolic root of the disease.

Metabolic correction: a functional biochemical mechanism against disease--Part 2: mechanisms and benefits.

A healthy physiology depends on a plethora of complex interdependent biochemical reactions. In order for these reactions to occur suitably, the enzymes and cofactors that regulate their flow must be present in the proper balance. The term metabolic correction is used to describe a biochemical-physiological process that improves cellular biochemistry as a means to an individual's achieving metabolic or physiological optimization.

Metabolic correction: a functional biochemical mechanism against disease--Part 1: concept and historical background.

Human physiology depends on countless biochemical reactions, numerous of which are co-dependent and interrelated. The speed and level of completion of reactions usually depend on the availability of precursors and enzymes. The enzymatic activity depends on the bioavailability of micronutrient cofactors such as vitamins and minerals.

High Dose Intraveneous Vitamin C and Chikungunya Fever: A Case Report.

The Chikungunya (CHIKV) fever is a viral disease produced by a single-stranded RNA Alphavirus from the Togaviridae genus. Its transmission occurs only through mosquito vectors, principally Aedes aegypti. It requires a human-mosquito-human transmission cycle.

Diet and stress.

Stress refers to a reaction given a particular stimulus. Stress is a common problem in most modern societies. Stress creates greater physiologic demands.

The bio-energetic theory of carcinogenesis.

The altered energy metabolism of tumor cells provides a viable target for a non toxic chemotherapeutic approach. An increased glucose consumption rate has been observed in malignant cells. Warburg (Nobel Laureate in medicine) postulated that the respiratory process of malignant cells was impaired and that the transformation of a normal cell to malignant was due to defects in the aerobic respiratory pathways.

Schedule Dependence in Cancer Therapy: Intravenous Vitamin C and the Systemic Saturation Hypothesis.

Despite the significant number of in vitro and in vivo studies to assess vitamin C effects on cancer following the application of large doses and its extensive use by alternative medicine practitioners in the USA; the precise schedule for successful cancer therapy is still unknown. Based on interpretation of the available data, we postulate that the relationship between Vitamin C doses and plasma concentration x time, the capability of tissue stores upon distribution, and the saturable mechanism of urinary excretion are all important determinants to understand the physiology of high intravenous vitamin C dose administration and its effect on cancer. Practitioners should pay more attention to the cumulative vitamin C effect instead of the vitamin C concentrations to account for observed discrepancy in antitumor response.

Intravenous ascorbic acid to prevent and treat cancer-associated sepsis?

The history of ascorbic acid (AA) and cancer has been marked with controversy. Clinical studies evaluating AA in cancer outcome continue to the present day. However, the wealth of data suggesting that AA may be highly beneficial in addressing cancer-associated inflammation, particularly progression to systemic inflammatory response syndrome (SIRS) and multi organ failure (MOF), has been largely overlooked.

Mitochondria, Energy and Cancer: The Relationship with Ascorbic Acid.

Ascorbic Acid (AA) has been used in the prevention and treatment of cancer with reported effectiveness. Mitochondria may be one of the principal targets of ascorbate's cellular activity and it may play an important role in the development and progression of cancer. Mitochondria, besides generating adenosine triphosphate (ATP), has a role in apoptosis regulation and in the production of regulatory oxidative species that may be relevant in gene expression.

Pharmacokinetics of vitamin C: insights into the oral and intravenous administration of ascorbate.

There is a strong advocacy movement for large doses of vitamin C. Some authors argue that the biological half-life for vitamin C at high plasma levels is about 30 minutes, but these reports are the subject of some controversy. NIH researchers established the current RDA based upon tests conducted 12 hours (24 half lives) after consumption.

Supraphysiological cyclic dosing of sustained release T3 in order to reset low basal body temperature.

The use of sustained release tri-iodothyronine (SR-T3) in clinical practice, has gained popularity in the complementary and alternative medical community in the treatment of chronic fatigue with a protocol (WT3) pioneered by Dr. Denis Wilson. The WT3 protocol involves the use of SR-T3 taken orally by the patient every 12 hours according to a cyclic dose schedule determined by patient response.

A pilot clinical study of continuous intravenous ascorbate in terminal cancer patients.

Case studies suggest that vitamin C, given intravenously at doses of 10-100 grams/day can improve patient well being and in some cases, reduce tumor size. While ascorbate is generally considered safe, clinical data on high intravenous doses is limited. Twenty-four late stage terminal cancer patients were given continuous infusions of 150 to 710 mg/kg/day for up to eight weeks.

Effect of a dietary supplement combination on weight management, adipose tissue, cholesterol and triglycerides in obese children.

A dietary supplement combination consisting of vitamins, minerals and fibers was studied to determine its safety and efficacy on weight/fat loss, cholesterol and triglycerides in children between ages 7-13. This open label trial measured total body weight, body fat percentage, waist circumference, total cholesterol, triglycerides before and after 6 weeks of treatment. The study population consisted of 25 mildly to moderate obese, otherwise healthy children of both sexes.

Effects of high dose ascorbate administration on L-10 tumor growth in guinea pigs.

Sodium ascorbate is preferentially toxic to tumor cells at high concentrations. It has not been established, however, whether sufficient intra-tumor ascorbate concentrations are safely achievable in vivo. We administered sodium ascorbate subcutaneously or orally for eighteen days to Sewall-Wright strain-2 guinea pigs bearing intradermal L-10 hepatocarcinoma tumors.
