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.

The acute effect of high-dose intravenous vitamin C and other nutrients on blood pressu... - 0 views

  • the reduction in BP within the first 10–20 min may be primarily attributed to a direct vasodilatory physiological effect, described as venodilation
  • BP reduction observed after 70–90 min is likely attributable to pharmacokinetically plausible vitamin C absorption and vasodilation because of nitric oxide release
  • Pharmacokinetic studies of IVC administration observed peak plasma levels within the first 90 min, with plasma levels reaching 13350 μmol/l for 50 g of IVC

  • Essential hypertension, associated with endothelial dysfunction because of an impaired nitric oxide/l-arginine pathway and impaired vasodilation can be restored by vitamin C
  • marked increase in BP response when IVB12 is administered
  • The mean BP increased significantly up to 12–16 mmHg systolic and diastolic independent of the dosage of vitamin B12
  • The production of norepinephrine, which can stimulate angiotensin-II production, which in turn influences BP, has been suggested as a possible mechanism for the increase in BP with IVB12
  • excess norephinephrine levels stimulate the sympathetic nervous system, leading to increased cortisol production, which has also been linked to increases in BP
  • Animal studies have found higher serum levels of norepinephrine (noradrenaline) in the adrenal medulla of rats receiving methylcobalamin (methyl-vitamin B12)
  •  
    IV vitamin C in mostly normotensive patients (> 30 grams) reduced blood pressure.  Some of the patients were pre-hypertensive. Vitamin B12 increase the blood pressure.

    Blood lead levels correlate with homocysteine levels.  Methylation (B12, Folate, B6) plays a role regulating homocysteine levels as well.

    Animal study points to methylB12 as the cause of an increase in adrenal medulla norepinephrine production.  This has significant implications in individuals with hypertension.
