The body needs minerals to function. Without adequate levels of sodium, potassium, calcium and magnesium we would perish.
Doctors often encourage patients to cut back on sodium and increase calcium. Potassium levels are monitored in routine blood tests, and if low, a potassium supplement is usually prescribed.
Magnesium, on the other hand, often gets short shrift. It is frequently the forgotten mineral, even though it is absolutely crucial for every cell in the body.
Drugs Can Lower Magnesium Levels:
Diuretics are found in most blood pressure medicines. Such drugs not only deplete the body of potassium they can also cause low levels of magnesium.
So can acid-suppressing drugs called proton pump inhibitors. These include esomeprazole (Nexium), lansoprazole (Prevacid) and omeprazole (Prilosec). Most people are unaware that their heartburn medicine or blood pressure pills could cause hypomagnesemia, (perilously low magnesium levels (Gastroenterology Research and Practice, online, May 4, 2015).
What Are the Dangers of Low Magnesium?
What happens when magnesium levels fall into the danger zone? Symptoms can include weakness, lethargy, loss of appetite, nausea, muscle cramps, irregular heart rhythms, depression, changes in personality, confusion and disorientation. If magnesium drops too low it can cause cardiac arrest.
Magnesium as a Home Remedy:
Magnesium is not only essential for good health, it has become a popular home remedy.
Readers report that magnesium is their best solution to constipation. After all, milk of magnesia remains a classic drugstore solution to this common complaint.
Here is just one of the many messages we have received along this line:
“I have a solution for constipation I would like to share with your readers. I take around 500 mg magnesium every night. The result is what ‘normal’ people experience: a regular, comfortable bowel movement. Nothing else I tried in the past helped me so gently.”
Too much magnesium can cause diarrhea, though, so don’t overdo.
Others report that magnesium helps against depression:
“Please tell your readers that taking moderate amounts of a magnesium supplement can alleviate depression. I have personally had good results taking magnesium at a dose of 400 mg a day.
“Last year my girlfriend had a friend who was suffering from major depression and had to go on disability from her teaching job as a result. She was under medical care, but still having a lot of difficulties. After we gave her a big bottle of magnesium tablets, she started to recover. She’s doing much better now and is back to teaching and going out and doing things. I can’t think of another treatment that is so cheap, simple and safe.”
Science supports this concept (Pharmacological Reports, vol. 63, number 3, 2013).
Other uses for magnesium include as a sleep aid, an antidote to leg cramps, a treatment for migraines and to help control blood sugar. Readers report that topical magnesium in the form of milk of magnesia can help control acne on the face and body odor when applied to underarms.

More Amazing Magnesium Stories:
We received this message 14 years ago:
“I have suffered from episodes of insomnia for years and have tried many remedies without relief. Cutting down on caffeine and taking valerian didn’t work. Over-the-counter sleep aids such as Benadryl and Tylenol P.M. made me groggy the next day. Even prescription drugs like Ambien didn’t help.
“Then a friend suggested I try taking magnesium at bedtime. Since I was already taking a calcium-magnesium supplement daily, I started taking the calcium in the daytime and the magnesium (250 mg) at night. Magnesium has helped my insomnia more than anything else I’ve ever tried. There are still occasional nights when I don’t sleep well, but they are few and far between.
“I have heard that magnesium supplements can cause diarrhea, but I haven’t had that problem. I hope this information will help someone else.”
Leg Cramps & RLS:
“Many people have horrible leg cramps and cannot take quinine because it has been taken off the market. I am 70 years old and have suffered with leg cramps all my life.
“Years ago, I used to take OTC quinine tablets, but quinine water never worked for me. A long time ago I found that 250 mg tablets of magnesium at bedtime worked like a charm in warding off leg cramps and restless leg syndrome.”
Magnesium for Migraines:
“I had been suffering from migraines since I was 12 years old. I had suddenly began to suffer from constipation as well. After I learned my food triggers for migraines (FINALLY @ 50 years of age!) and that did help, but if a low pressure weather system visited my area, I would get a raging migraine…what can one do about the weather?
“OK, back to the constipation problem. I started taking chelated magnesium, 250mg, 3 each every night before bed (this is an EarthFare brand). No more constipation, but better yet, I have not had a migraine in literally months!”
OK. We could go on and on about the benefits of magnesium. You can learn a great deal more about this amazing mineral by putting “magnesium” into a search on our PeoplesPharmacy.com website.
A word of caution: too much magnesium can be hard on the kidneys if they are not functioning normally. As mentioned, diarrhea is often a tip off that someone is getting too much of this mineral.
