Magnesium----what kind?

Postby MissKaty » Fri Aug 05, 2005 7:07 pm

I am trying to find out more about magnesium as that keeps popping up in some of the posts regarding it helping anxiety & helping to sleep. I have magnesium there different kinds?

I did find out that what I had was very low dose & hardly any use at all. It's only 100mg & you're supposed to take it 4 times a day. I've only been popping one at night with 600 of Calcium & now find that I am taking to much calcium.

What would be a good one tablet type product that would have the right amount of each that I could take at bedtime without other ingredients that may interact with my zoloft & zestril that I take for HBP.

Also, what about the omega Dr. told me to take it but didn't specify dosage, type, etc.

Thanks so much for all your help.

Magnesium citrate is just fine. A rule of thumb suggested by Jean Carper, a well-known nutritionist, is to take half as much magnesium as calcium. So if you are taking 600 mg calcium, take 300 mg magnesium. I don't know any particular product to recommend. I buy my supplements from as their products are rated high by consumer labs and they often run excellent sales.

You mentioned that you're taking Zoloft. This should be helpful for your anxiety; are you sure you're on the best possible dose for you? If it's not helping your anxiety, maybe another antidepressant/anti-anxiety medication might work better.

Here's some additional info about how and what kind of magnesium to take:

My recommendation for calcium is to take it in either a liquid or soft gelcap form and it should have magnesium AND Vitamin D in it (Vitamin D plays a major role in calcium absorption and bone health. The relationship between calcium absorption and vitamin D is similar to that of a locked door and a key. Vitamin D is the key that unlocks the door and allows calcium to leave the intestine and enter the bloodstream. Vitamin D also works in the kidneys to help resorb calcium that otherwise would be excreted.) I found the liquid form at a health food store that had both the right amount of magnesium and the Vit D. The pills are just too compacted and don't dissolve quickly enough in our system to give us any benefit, so we're "passing" most of the good stuff which means "wasted" $$$$. :)

I've gather some info on these two pages that might be helpful:

Also this site has some valuable information about calcium intake:

The site Dr. Judy recommended looks ok (and I did see some gelcaps listed under the calcium products), but they also promote coral calcium and from everything I've read and heard, the claims made about coral calcium are not valid.

Finally, here's an excerpt from Dr. Andrew Weil's site about calcium:
Taking too much calcium (three to four times the usual dose) can lead to such side effects as constipation, dry mouth, a continuing headache, increased thirst, irritability, loss of appetite, depression, a metallic taste in the mouth, and fatigue.

Of the many calcium supplements available, I recommend calcium citrate, because it is more easily assimilated than other forms, especially by older people with less stomach acid. Calcium carbonate is more easily available and less expensive but not as well absorbed. It is OK to use calcium supplements containing vitamin D. In fact, I recommend taking between 400 and 800 IU of vitamin D a day to insure proper absorption and use of calcium. Along with your calcium supplements, be sure to take magnesium (half the dose of your calcium supplement); without it you may find that the calcium is constipating.
