Brigid Titgemeier says magnesium supplementation can lower blood pressure even in people who aren't deficient. For hypertension or high-risk patients, she recommends it first, along with magnesium-rich foods. Micronutrients from food can work like medicine.

Magnesium supplementation has been shown to lead to significant reductions in blood pressure. When a person has high blood pressure, over 140 over 90, they don't have to have a magnesium deficiency in order for them to experience improvements in lowering blood pressure from magnesium supplementation. So this is definitely an area where, in working with clients or even recommending to family and friends, if a person has high blood pressure or is at risk of high blood pressure, this is one of the first nutrients that we'll recommend, in addition to course, working on food-based sources of magnesium that can be increased in the diet. It's so amazing, just one example of how much food really can be medicine when looking at the importance of these micronutrients.
