Daily magnesium supplements significantly reduce blood pressure, new research reveals.
Taking a 300mg tablet, the recommended dose for males, lowers hypertension and boosts blood flow after just one month, a study review found.
Researchers recommend magnesium supplements be considered for people suffering from, or at-risk of, high blood pressure.
Yet, other experts argue dietary sources of the mineral, such as leafy greens, bananas and nuts, are sufficient to keep magnesium levels topped up.
Excessive levels of the mineral can cause side effects, including diarrhea.
