Magnesium intake of 500 mg/d to 1000 mg/d may reduce blood pressure (BP) as much as 5.6/2.8 mm Hg. However, clinical studies have a wide range of BP reduction, with some showing no change in BP.
After further analyzing the data, the researchers concluded that taking 300 mg of magnesium supplements daily for one month could result in lower blood pressure and higher levels of magnesium in the blood.
Magnesium taurate may be the best form for managing high blood sugar and high blood pressure, though more studies are necessary.
Many doctors consider magnesium taurate⁹ the best supplement for people with hypertension (high blood pressure). Studies in rats show that it can help lower high blood pressure and protect your heart.
Magnesium supplementation resulted in a mean reduction of 4.18 mm Hg in SBP and 2.27 mm Hg in DBP. Conclusion: The pooled results suggest that magnesium supplementation significantly lowers BP in individuals with insulin resistance, prediabetes, or other noncommunicable chronic diseases.
Magnesium begins to take effect after one week of consistent supplementation.
Various genetic defects in magnesium transport are associated with hypertension and possibly with cardiovascular disease. Oral magnesium acts as a natural calcium channel blocker, increases nitric oxide, improves endothelial dysfunction, and induces direct and indirect vasodilation.
Foods high in vitamin C, vitamin E, potassium, selenium or L-arginine are good options if you're looking to lower your blood pressure. Antioxidants protect your cells from damage and can reduce inflammation, which, in turn, can keep blood pressure in control.
High doses of magnesium from supplements or medications can cause nausea, abdominal cramping and diarrhea. In addition, the magnesium in supplements can interact with some types of antibiotics and other medicines.
People with diabetes, intestinal disease, heart disease or kidney disease should not take magnesium before speaking with their health care provider. Overdose. Signs of a magnesium overdose can include nausea, diarrhea, low blood pressure, muscle weakness, and fatigue. At very high doses, magnesium can be fatal.
In conclusion, the present study points toward potassium, rather than magnesium or calcium, as the cause of lower blood pressures in populations and provides support for nutritional guidelines to increase dietary potassium to prevent hypertension.
Nassar says that taking a magnesium supplement every day likely isn't unsafe for most people. Just be sure you're not taking too much magnesium. The maximum dietary allowance for most adults is around 400 mg or less.
Therefore, magnesium supplements can be taken at any time of the day, as long as you're able to take them consistently. For some, taking supplements first thing in the morning may be easiest, while others may find that taking them with dinner or just before bed works well for them.
Research shows that some supplements may help lower blood pressure. These include magnesium, potassium, vitamin D, CoQ10, garlic, and fish oil.
Taking magnesium with these medications might cause blood pressure to go too low. Some of these medications include nifedipine (Adalat, Procardia), verapamil (Calan, Isoptin, Verelan), diltiazem (Cardizem), isradipine (DynaCirc), felodipine (Plendil), amlodipine (Norvasc), and others.
Magnesium plays many crucial roles in the body, such as supporting muscle and nerve function and energy production. Low magnesium levels usually don't cause symptoms. However, chronically low levels can increase the risk of high blood pressure, heart disease, type 2 diabetes and osteoporosis.
While there is no cure for high blood pressure, it is important for patients to take steps that matter, such as making effective lifestyle changes and taking BP-lowering medications as prescribed by their physicians.
Vitamin D deficiency may be linked to heart disease and an increased risk of high blood pressure (hypertension).
It is well documented that both magnesium and vitamin D have a positive effect on hypertension.
Transdermal magnesium products begin working straight away, as they are delivered directly to the epidermis. This bypasses the digestive system, where nutrients can be poorly absorbed and which is why so many people don't get the magnesium they need through diet alone.
Refining or processing of food may deplete magnesium content by nearly 85%. Furthermore, cooking, especially boiling of magnesium-rich foods, will result in significant loss of magnesium. The processing and cooking of food may therefore explain the apparently high prevalence of low magnesium intake in many populations.
