can one take too much magnesium?

I take St. John's Wort for depression and a few months ago, started taking a b-complex vitamin and magnesium supplement as well because I was told that many people who suffer from depression are often deficient in b-12, folic acid and magnesium. Right now, I'm reevaluating what vitamins and take and if they are really necessary. Is it okay to take magnesium not knowing if you are actually deficient in it? The one I take is called magnesium with chelated zinc. The bottle says take 3 a day (400mg), I only take 1. Can this have any negative impact on me at all?

Also, I take an acidophilus tablet every day, (again, not even the dosage recommended on the bottle - I take one, the bottle says take two per day, each serving contains 40 million live cells). Is there any reason I shouldn't be taking this? I haven't experienced any negative side effects since I started taking these vitamins. I just feel like I should be double-checking that this is all okay. Thank you.

Re: can one take too much magnesium?

In a healthy diet most additional vit/minerals your body doesn't need so it is all flushed out in the urine. People that take additional vit/minerals/supplements have very expensive urine...but it is of no additional benefit to the body. The only supplements you have to worry about are the oily ones that can build up in your system and cause trouble. There is no scientific evidence that St. Johns helps with depression so that too is washed away in the urine. But good luck with whatever you are trying to accomplish.

Re: can one take too much magnesium?

Many people are deficient in magnesium without knowing it. 400 mg. shouldn't cause any problems, especially if chelated. Acidophilus as well shouldn't cause problems. I also take a probiotic year round.

I have had good results with vitamin supplementation and don't feel that I'm "wasting money". The money I spend on vitamins far outweighs the side effects people experience from taking meds. But if you are concerned you can have a blood draw to determine your need for calcium, magnesium, B-12 and such. My doctor does this twice a year. Actually, I would highly recommend this as taking something without being sure you should be doing so could in itself have negative effects.

All the Best!
