After 4 days, the required vasopressor dose (medication that tends to…

Vitamin C may reduce the duration of mechanical ventilation in critically ill patients

Summary This meta-analysis included 8 trials with 685 patients in total. Results showed that vitamin C decreased the length of mechanical ventilation on average by 14%. Vitamin C showed beneficial effects, particularly in patients with the longest ventilation (most severe diseased patients). In 5 trials, including 471 patients requiring ventilation for over 10 hours, ventilation…

Green tea extract can reduce total and LDL cholesterol

Summary A double-blind, placebo-controlled study conducted by the University of Nashville investigated the relationship between a dietary supplement containing green tea extract and its effect on cholesterol levels. 240 men and women over 18 years of age with low to moderate increases in blood cholesterol (hypercholesterolemia) were examined over a period of 3 months. Study…

Catechin supplementation associated with significant reduction in LDL cholesterol levels

Summary In another large randomized, placebo-controlled clinical trial, which involved several American universities, the influence of green tea extracts (catechins) was investigated. The study participants were all postmenopausal women, with 936 of them completing the one-year trial. Compared to the control group, catechin supplementation was associated with a significant reduction in total and LDL cholesterol…

Increased vitamin C blood levels associated with reduction in LDL cholesterol and increase in HDL cholesterol

Summary As early as 1992, the USDA Human Nutrition Research Center at Tufts University in Boston published a randomized field study involving several hundreds of participants of all age groups. The results of the study showed that increased vitamin C blood levels were associated with a reduction in LDL cholesterol (“bad cholesterol”) and an increase…

Supplementation with vitamin D can improve insulin needs

Summary Diabetes is a known risk factor during pregnancy, when the disease can lead to serious complications as a result of metabolic disorder. A randomized, controlled study at Shanghai University Hospital investigated the effect of vitamin D on the progression of gestational diabetes.

Vitamin D treatment benefits type 1 diabetes patients

Summary In another randomized and controlled clinical trial, a joint team of researchers from the University Hospitals of Frankfurt and Hanover examined the effects of vitamin D administration on diabetes progression. The results of this clinical study showed that vitamin D supplementation significantly reduced insulin demands and significantly improved long-term blood glucose levels (HbA1c). No…

Vitamin D supplement can reduce long-term diabetes score

Summary 60 patients with type 2 diabetes and low vitamin D levels were enrolled in a placebo-controlled, randomized clinical trial to investigate the effect of vitamin D supplementation on the progression of the disease. Patients who received a vitamin D supplement had a significant reduction in their long-term diabetes score (HbA1c). Blood pressure and blood…

Coenzyme Q10 supplements can reduce mortality from cardiovascular disease

Summary Another randomized double-blind study was conducted as part of an international collaboration between the universities of Copenhagen, Melbourne, Vienna, Warsaw and other hospitals. The study included 420 patients and investigated the influence of coenzyme Q10 supplementation on the progression of chronic heart failure over a period of 2 years. According to the researchers, coenzyme…

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.…

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…
