Magnesium in an important intracellular ion. That said, it's very important in the body. I looked up some articles that stated that chronic mag. deficiencies have been shown to cause mitral valve prolapse, muscle tension or general muscle pain and heavy set anxiety. Anyone here suffer from those things?
One of the ways magnesium works is by relaxing your blood vessels. This is one way it helps with anxiety. Another way is by lowering catecholamine levels in your body. In other words, it lowers stress hormones like epinephrine (Adrenaline). This is another way magnesium can help you relax. The are many other important functions in the body. I'm trying to get more information since I use this supplement myself to treat the problems stated above.
Another article by Dr. mercola (mercola.com) stated that magnesium deficiencies are common in the states and most people are unaware of this. I checked my own magnesium blood levels recently and it showed that I was deficient. So there you go.
The recommended daily dose is about 400 mg/day. If you're deficient, you'll need to intake some to counter the imbalance, then a little more to have a therapeutic effect. So if you're worried you'll be stuck in the ****ter, you'll need to take a whole lot of it to cause that effect.
The most absorbable form of magnesium in the citrate salt, or just magnesium citrate. I buy a brand from Solaray called magnesium asporotate that combines all of the best absorbable forms.
I can tell you this have done wonders for my anxiety. It's practically gone.
I hope this helps anyone...
