1. Involuntary Muscle Twitches
The occasional muscle twitch or cramp is nothing to worry about, but if you are constantly experiencing shoulder twitches or leg cramps, you may need a magnesium supplement. Adding magnesium can reduce body aches and pains, muscle cramps, and muscle spasms.
2. You're Depressed or Apathetic
Low energy in winter is common, and SAD could be to blame. Low moods and apathy can also suggest low levels of magnesium. Scientists speculate that low magnesium is also a factor in anxiety disorders. If you're feeling blue, adding magnesium to your diet won't hurt — and it could give you the jolt you need to be yourself again.
