I have no idea what brand supplement was used in the study. My “magnesium” journey is, for lack of a better word, interesting. Around 2016, I was experiencing a lot of tingling in my extremities. My doctors offered nothing of value—didn’t know what was causing the tingling, had no recommendations or advice, and the tests that were run showed nothing. I did my own research and found that a magnesium deficiency can cause tingling and asked a doctor about this and the doctor did a blood test and my magnesium levels were normal so I decided not to take magnesium supplements. Eventually, I discovered that I had hypothyroidism, which can cause tingling along w/ a million other issues. Two yrs after being diagnosed w/ hypothyroidism, I had my 1st DEXA and was told I have osteoporosis. Approximately 2 yrs later, after being disappointed w/ the lack of info/help from my endocrinologist, I started doing my own research. That’s when I learned that blood work (labs) that show that your magnesium levels are in the normal range don’t mean that you don’t have a magnesium deficiency—you’d think this is something a doctor would tell a patient, especially when the patient specifically brought up a concern of potentially being magnesium deficient. During my research I’ve also discovered that many doctors believe pms might be “caused by” a magnesium deficiency—pre-menopause, I suffered from horrible pms ( https://www.biospherenutrition.co.nz/blogs/magnesium/magnesium-for-premenstrual-syndrome-pms ). Additionally, there is a link between magnesium deficiency and migraines. HELLO. I’ve had migraines since my teens. Fortunately, they aren’t that frequent. Of course, while doing my research, I learned that magnesium is necessary for bone health and through a couple of online osteoporosis groups, I discovered that many women diagnosed w/ osteoporosis add magnesium supplements so I bought a bottle of Spring Valley Magnesium Citrate and started taking 100 mg a day (24% of the RDA). I now take 200 mg of magnesium citrate a day (one in the afternoon, the other late at night) and I switched my calcium supplement to Jarrow’s BoneUp, which contains 166.7 mg of magnesium oxide per serving, so right now, I take 366.7 mg of magnesium per day.

So would I(like the name of the multi-vitamin mineral supplement containing twice the RDA of magnesium.
