Daily vitamin D supplementation beneficially affects high blood pressure

Summary According to research, low vitamin D levels are associated with higher blood pressure. This study, executed by research departments in Switzerland and the USA, aimed to determine whether higher daily vitamin D supplementation (2000 IU or 50µg) is more effective in controlling blood pressure among older adults than vitamin D supplementation with a standard…

Vitamin C supplementation improves inflammation in obese adults

Summary Obesity is associated with chronic inflammation. Thus, this study investigated the anti-inflammatory capacity of vitamin C in obese patients. 64 obese participants with high blood pressure and/or diabetes and high levels of inflammatory markers were enrolled into either the experimental group (31 patients) or the control group (33 patients). The experimental group was treated…

Flavonoid-rich diet improves gut health

Summary A study executed by researchers from Germany and Northern Ireland showed that a diet rich in flavonoids improves gut health by creating a more diverse composition of the microbiome. The study was performed with 904 German people. Specifically, an association of up to 15% was observed between lower systolic blood pressure and flavonoid-rich food,…

Quercetin lowers the blood pressure of hypertensive patients

Summary A study conducted in the USA investigated the efficacy of quercetin against high blood pressure (hypertension). For this purpose, participants with elevated blood pressure values and participants with a mild form of hypertension were given 730 mg of quercetin daily for 28 days. It was found that quercetin supplementation contributed to a reduction in…

Spirulina algae shows positive effect on cardiovascular system

Summary The Medical University of Poznan in Poland investigated the effect of spirulina algae on the cardiovascular system of obese people with high blood pressure. For this purpose, 50 eligible patients were examined who received a daily dose of 2 g spirulina for 3 months. Positive changes in insulin sensitivity, plasma lipid levels, biomarkers of…

Magnesium can help lower blood pressure

Summary This intervention study investigated the effects of magnesium supplementation on blood pressure and blood flow in the blood vessels. For one month, 48 patients took a daily supplement of 300 mg magnesium oxide. Blood pressure, blood flow, stroke volume, stroke index, cardiac output, cardiac index, left heartbeat, and heart rate were measured. The evaluations…

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…

Coenzyme Q10 supplementation can reduce systolic blood pressure

Summary An analysis of 12 clinical trials investigated the correlation between coenzyme Q10 supplementation, a cofactor of cellular energy metabolism, and hypertension. Based on all results, the researchers concluded that coenzyme Q10 supplementation can reduce systolic blood pressure by up to 17 points (mmHg) and diastolic blood pressure by up to 10 points. Among the…

Increased vitamin C intake associated with lower blood pressure

Summary A study at the University Hospital of Amsterdam with more than 2,700 participants showed that an increased vitamin C intake was associated with lower blood pressure and other positive parameters. Most importantly, the group of people with the highest vitamin C intake had a one-third lower risk of developing coronary heart disease compared with…
