Such symptoms are not generally serious, especially if they resolve with temporary discontinuation of vitamin C supplementation. In a cohort of 21,831 adults followed for 12 years in the EPIC-Norfolk study, high plasma vitamin C was found to be strongly associated with a reduced risk of diabetes(84).

Effects of vitamin C supplementation on blood pressure: a meta-analysis of randomized controlled trials. Hankey GJ. In another AD mouse model that was lacking the ability to synthesize vitamin C, supplementation with a high versus low dose of vitamin C reduced amyloid deposition in the cortex and hippocampus and limited blood-brain barrier impairments and mitochondrial dysfunction (99).

Two large prospective cohort studies assessed the relationship between dietary and supplemental vitamin C intakes and mortality. Prenatal vitamin C and E supplementation in smokers is associated with reduced placental abruption and preterm birth: a secondary analysis. While most generally healthy young adults can achieve these plasma concentrations with daily vitamin C intake of at least 200 mg/day, some individuals may have a lower vitamin C absorptive capacity than what is currently documented. (PubMed), 72. Andres M, Sivera F, Falzon L, Buchbinder R, Carmona L. Dietary supplements for chronic gout. A 2018 meta-analysis of randomized controlled trials investigating the effect of antioxidant vitamin supplementation in patients with type 2 diabetes found that most improvement in markers of oxidative stress and blood glucose control could be attributed to vitamin E(145).

Amelioration of persistent left ventricular function impairment through increased plasma ascorbate levels following myocardial infarction. Levine M, Wang Y, Padayatty SJ, Morrow J. The effect of vitamin C, alone or with allopurinol, decreasing serum uric acid was modest and much less than that of allopurinol alone. It may involve the production of high levels of hydrogen peroxide, selectively toxic to cancer cells (22, 160-162), or the deactivation of hypoxia inducible factor, a prosurvival transcription factor that protects cancer cells from various forms of stress (159, 163, 164). Improved endothelial function was observed with daily vitamin C doses above 500 mg (39). (PubMed), 79 Park Y, Spiegelman D, Hunter DJ, et al. (PubMed), 100. I use it myself. Some notes on Linus Pauling. P R Health Sci J. Calcium ascorbate: Calcium ascorbate generally provides 90-110 mg of calcium (890-910 mg of ascorbic acid) per 1,000 mg of calcium ascorbate. Dr. Pauling significantly increased his recommendation in his 1986 book How To Live Longer and Feel Better. Carcinogenesis. The role of vitamin C as a cofactor is also related to its redox potential. A population-based, prospective study, the Iowa Womens Health Study, collected baseline data on diet and supplement use in 35,159 women (aged 55-69 years) and evaluated the risk of developing non-Hodgkin lymphoma (NHL) over 19 years of follow-up (80). Depletion-repletion pharmacokinetic experiments demonstrated that plasma vitamin C concentration is tightly controlled by three primary mechanisms: intestinal absorption, tissue transport, and renal reabsorption (22). A meta-analysis of 10 trials that examined antioxidant vitamins, of which five included vitamin C, found no association between any antioxidant vitamin (vitamin C, vitamin E, or -carotene), administered alone or in combination, and risk of stroke (60). The protocol also limited microvascular dysfunction (i.e., improved microcirculatory perfusion) and improved left ventricular ejection fraction at discharge (on day 84) (138, 139).

Although trials do not currently support the use of high-dose supplementation with vitamin C in cataract prevention, there is a consistent inverse association observed between high daily intake of fruit and/or vegetables (>5 servings/day) and risk of cataract (113). Antioxidant vitamin supplementation for preventing and slowing the progression of age-related cataract. Patients are advised to discuss with their oncologist before using vitamin C supplements (200, 201). 2011;30(6):477-483.

Other trials also failed to show any evidence of an effect of vitamin C on the risk of stroke. While acute scurvy can be prevented by a mere 10 mg vitamin C per day, there is no current research showing how much vitamin C might be required to prevent the atherosclerotic plaques of chronic scurvy. Lykkesfeldt J, Poulsen HE. The Linus Pauling Institute's Micronutrient Information Center provides scientific information on the health aspects of dietary factors and supplements, food, and beverages for the general public.

These products are all Lp (a) binding inhibitors. (PubMed), 50. Free Radic Biol Med. 2010;19(5):360-365. Scientific studies investigating vitamin C efficacy to prevent or treat disease need to assess baseline vitamin C status before embarking on an intervention or statistical analysis (22, 29-31). A phase I study in nine patients with metastatic pancreatic cancer showed that millimolar concentrations of plasma vitamin C could be reached safely when administered in conjunction with the cancer chemotherapy drugs, gemcitabine and erlotinib (168). In spite of the variable association depending on source, these analyses indicate an overall inverse association between higher vitamin C intakes and CHD risk. (PubMed).

In response to invading microorganisms, phagocytic leukocytes release non-specific toxins, such as superoxide radicals, hypochlorous acid ("bleach"), and peroxynitrite; these reactive oxygen species kill pathogens and, in the process, can damage the leukocytes themselves (15). Lykkesfeldt J, Christen S, Wallock LM, Chang HH, Jacob RA, Ames BN. Liability for individual actions or omissions based upon the contents of this site is expressly disclaimed. PHS II found that vitamin C supplementation (500 mg/day) for an average of eight years had no significant effect on major cardiovascular events, total myocardial infarction, or cardiovascular mortality (53).

Pauling LC. 1998;147(12):1162-1174. The most recent large prospective cohort study found an inverse association between dietary vitamin C intake and CHD mortality in Japanese women, but not in men (48). Nutr Rev. Such symptoms appear to be related to the weakening of blood vessels, connective tissue, and bone, which all contain collagen. Semin Arthritis Rheum. Diabetes Care. Carr AC, Pullar JM, Bozonet SM, Vissers MC. Int J Vitam Nutr Res. Most multivitamin supplements provide at least 60 mg of vitamin C. Whether older adults have higher requirements for vitamin C is not yet known with certainty, yet some older populations have been found to have vitamin C intakes considerably below the RDA of 75 and 90 mg/day for women and men, respectively (207). river cats parking pass, bbsrc industrial partnership awards, edward heathcoat amory,
