Vitamin C supplementation leads to significant reduction in blood pressure

Summary An analysis of 8 clinical trials investigating the association between vitamin C supplementation and essential hypertension showed that vitamin C supplementation led to a significant reduction in blood pressure. For daily supplementation above 500 mg of vitamin C, these results were even statistically significant (P = 0.005). What is particularly remarkable about this research…

Dietary supplement containing quercetin can reduce blood pressure

Summary In a double-blind, placebo-controlled trial with patients suffering from an early form of hypertension (pre-hypertension and stage 1 hypertension), the effect of quercetin on blood pressure was investigated. This dietary supplement led to a reduction in both systolic and diastolic blood pressure. The reduction in diastolic blood pressure was statistically significant (P < 0.01).…

Arginine supplementation can lead to highly significant reduction in blood pressure

Summary In an evaluation of 11 double-blind, placebo-controlled trials, the correlation between dietary supplementation with the natural amino acid arginine and changes in blood pressure was investigated. The analysis of these trials showed that arginine supplementation led to a highly significant reduction in both systolic and diastolic blood pressure. One particularly remarkable aspect of this…

Dietary supplement can improve pumping function of the heart

Summary In a randomized clinical trial involving patients suffering from chronic heart failure, the effect of dietary supplements containing a vitamin-mineral combination was investigated. The study was carried out at the Charité Clinic in Berlin and showed that the pumping function of the heart (left ventricular ejection fraction) was significantly improved by the dietary supplement.…

Vitamin C prevents hypercholesterolemia induced atherosclerosis

Summary This study investigated the effect of vitamin C on the development of hypercholesterolemia (high blood levels of cholesterol) induced atherosclerosis. The experiments were performed with rabbits, and they showed that a high dose of vitamin C was effective in reducing atherosclerosis. The results suggest that vitamin C can prevent hypercholesterolemia induced atherosclerosis. Further details…

Effectiveness of vitamin C supplementation in patients with heart attacks and reperfusion

Summary Reperfusion is a treatment which aims to restore the blood flow to body´s tissues which are blood flow deficient, but it can damage organs and tissues by increasing oxidative stress (imbalance between the production of free radicals and the ability of the body to counteract their harmful effects). The present study investigated the effect…

Low blood levels of selenium are associated with complications after heart surgery

Summary This study evaluated the blood levels of selenium in patients undergoing heart surgery. Blood selenium was measured in 40 patients before and after heart surgery. The results showed a decrease in selenium levels after the operations. The researchers concluded that low blood levels of selenium are associated with development of complications after heart surgery.…

Vitamin B12 supplementation should be encouraged during the rehabilitation period after heart surgery

Summary This study investigated the nutrition status in patients admitted to rehabilitation after heart surgery. Blood samples were collected from 50 patients and analyzed. The results showed that vitamin B12 supplementation should be encouraged because of its substantial reduction during the rehabilitation period after surgery; in addition, it was found that the diet followed during…

Protective effects of magnesium in patients undergoing coronary angioplasty for heart attack

Summary This study evaluated the effect of magnesium in patients undergoing coronary angioplasty (a procedure used to open the clogged arteries of the heart) for heart attack. 180 patients with heart attacks underwent successful coronary intervention. They were treated either with intravenous (directly injected into a vein) magnesium or with an intravenous solution without magnesium.…

Magnesium supplementation reduces irregular heartbeat

Summary This review examined the efficacy of magnesium supplementation on arrhythmias among children undergoing heart surgery. 5 studies were investigated and a total of 348 participants were included. The results showed that magnesium supplementation significantly reduced arrhythmias in children undergoing heart surgery. More details can be found in the study.

Lower levels of folate and vitamin B6 increase the risk of atherosclerosis

Summary High levels of the amino acid homocysteine increase the risk of atherosclerosis. This study evaluated the relationship between homocysteine, atherosclerosis and B vitamins. 750 patients with vascular disease were compared with 800 healthy people. Blood levels of homocysteine, folate, vitamin B12 and vitamin B6 were determined. The results showed that lower levels of folate…

Arginine improves circulatory problems

Summary This study investigated the effects of the amino acid arginine on peripheral vascular disease, a common circulatory problem in which narrowed arteries reduce blood flow to the limbs. 39 patients were given either arginine, a conventional drug or no treatment for 3 weeks. The results showed that arginine improved the symptoms of peripheral arterial…

Vitamin B1 improves heart function

Summary This study evaluated the effect of vitamin B1 (thiamine) supplementation in patients with heart failure. 9 patients were given vitamin B1 or a placebo for 28 days. The results showed that vitamin B1 had beneficial effects on the heart function of the studied heart failure patients. Further details can be found in the study.…

Inadequate micronutrient intake increases risk of high blood pressure

Summary This study analyzed the relationship between the intakes of micronutrients (vitamins and minerals) and developing high blood pressure. Vitamin and mineral intakes were estimated from a three-day food record in 120 children. The researchers found that intakes of vitamin D, calcium and potassium were inadequate, whereas sodium intake was considered to be too high.…

Fish oil reduces blood pressure

Summary The force with which blood is pressed against blood vessel walls represents the measurable blood pressure. The level of our blood pressure is directly dependent on various factors, in particular on the pumping force of the heart, the blood volume, and the elasticity of the blood vessels. Hypertension is a chronic medical condition in…

Pantethine, a derivative of vitamin B5, helps in normalizing various lipid metabolism disorders

Summary Lipid disorders are characterized by imbalanced levels of fatty substances (i.e. cholesterol and triglycerides) in the bloodstream. These lipids are carried in the blood stream in form of microscopic round particles, called lipoproteins. Thus, these conditions are also called lipoprotein disorders. There are, generally speaking, two types of cholesterol-transporting lipoproteins: a) the “bad cholesterol”…

Coenzyme Q10 increases physical performance in patients with angina pectoris (chest tightness)

Summary The underlying disease process of coronary artery disease (CAD) is called arteriosclerosis. This process starts with a weakening of the blood vessel walls, most frequently caused by an insufficient dietary intake of vitamins and other micronutrients. This leads to an underproduction of collagen and other reinforcement molecules in the artery walls and to the…
