Micronutrients & recovery
Magnesium supplementation (20 mmol/d for 8 weeks) significantly lowers blood pressure in hypertensive patients, with the magnitude of reduction being greater in those with higher baseline blood pressure.
If you have high blood pressure, taking 480mg of magnesium oxide daily for at least 8 weeks may help lower it slightly, especially if your blood pressure is currently high. It is not a replacement for medication but a supportive lifestyle addition. Monitor your blood pressure to see if you respond, as those with higher starting pressures tend to see more benefit.
These results indicate that magnesium supplementation lowers BP in hypertensive subjects and this effect is greater in subjects with higher BP.
Why this rating
Randomized crossover design with ambulatory and home BP monitoring reduces bias, but the sample size is moderate (n=60) and the effect size is small.
