The study design was a follows: “ An open-label, blocked, randomized, cross-over trial was carried out in outpatient primary care clinics on 126 adults (mean age 52; 38% male) diagnosed with and currently experiencing mild-to-moderate symptoms with Patient Health Questionnaire-9 (PHQ-9) scores of 5–19.
The intervention was 6 weeks of active treatment (248 mg of elemental magnesium per day) compared to 6 weeks of control (no treatment). Assessments of depression symptoms were completed at bi-weekly phone calls.
The primary outcome was the net difference in the change in depression symptoms from baseline to the end of each treatment period. Secondary outcomes included changes in anxiety symptoms as well as adherence to the supplement regimen, appearance of adverse effects, and intention to use magnesium supplements in the future. Between June 2015 and May 2016, 112 participants provided analyzable data.” The study results were as follows: “Consumption of magnesium chloride for 6 weeks resulted in a clinically significant net improvement in PHQ-9 scores of -6.0 points (CI -7.9, -4.2; P0.001) and net improvement in Generalized Anxiety Disorders-7 scores of -4.5 points (CI -6.6, -2.4; P0.001). Average adherence was 83% by pill count.
The supplements were well tolerated and 61% of participants reported they would use magnesium in the future. Similar effects were observed regardless of age, gender, baseline severity of depression, baseline magnesium level, or use of antidepressant treatments. Effects were observed within two weeks. Magnesium is effective for mild-to-moderate depression in adults. It works quickly and is well tolerated without the need for close monitoring for toxicity.” For perspective, conventional antidepressant drugs are considering to generate an “adequate or complete treatment response” with a PHQ-9 score “decrease of 5 points or more from baseline.” At this level of efficacy, their recommended action is: “Do not change treatment; conduct periodic follow-up.” The magnesium’s score of -6.0 therefore represents the height of success within conventional expectations for a complete response, which is sometimes termed “remission.” In contradistinction, conventional antidepressant drugs result in nearly half of patients discontinuing treatment during the first month, usually due to their powerful and sometimes debilitating side effects.8 To summarize the main study outcomes: The study authors concluded: “Magnesium is effective for mild-to-moderate depression in adults. It works quickly and is well tolerated without the need for close monitoring for toxicity.” Magnesium is a central player in your body’s energy production, as its found within 300 enzymes in the human body, including within the biologically active form of ATP known as MG-ATP. In fact, there have been over 3,751 magnesium binding sites identified within human proteins, indicating that it’s central nutritional importance has been greatly underappreciated. Research relevant to magnesium has been accumulating for the past 40 years at a steady rate of approximately 2,000 new studies a year. Our database project has indexed well over 100 health benefits of magnesium thus far. For the sake of brevity, we will address seven key therapeutic applications for magnesium as follows: It is quite amazing to consider the afformentioned side benefits of magnesium consumption or supplementation within the context of the well-known side effects of pharmaceutical approaches to symptom management of disease. On average, conventional drugs have 75 side effects associated with their use, including lethal ones (albeit sometimes rare). When considering magnesium’s many side benefits and extremely low toxicity, clearly this fundamental mineral intervention (and dietary requirement) puts pharmaceutical approaches to depression to shame.
The best source of magnesium is from food, and one way to identify magnesium-containing foods are those which are green, i.e. chlorophyll rich. Chlorophyll, which enable plants to capture solar energy and convert it into metabolic energy, has a magnesium atom at its center. Without magnesium, in fact, plants could not utilize the sun’s light energy. Magnesium, however, in its elemental form is colorless, and many foods that are not green contain it as well.
The point is that when found complexed with food cofactors, it is absorbed and utilized more efficiently than in its elemental form, say, extracted from limestone in the form of magnesium oxide. The following foods contain exceptionally high amounts of magnesium.
The portions described are 100 grams, or a little over three ounces. Fortunately, for those who need higher doses, or are not inclined to consume magnesium rich foods, there are supplemental forms commonly available on the market. Keep in mind, for those who wish to take advantage of the side benefit of magnesium therapy, namely, its stool softening and laxative properties, magnesium citrate or oxide will provide this additional feature. For those looking to maximize absorption and bioavailability magnesium glycinate is ideal, as glycine is the smallest amino acid commonly found chelated to magnesium, and therefore highly absorbable.
