Calcium Magnesium Ratio

It's important to take a 1:1 ratio of calcium to magnesium.  Dr. Carolyn Dean writes about it a lot, saying that Americans have an unhealthy ratio of about 10:1 calcium to magnesium.  And it is very important to consider all sources of calcium (diet and supplements) when adding up your amounts.

Here's a great video from about the importance of calcium magnesium balance:

What irritates me is that there are a lot of supplement brands out there that will combine their magnesium and calcium in the same supplement.  In Dr. Dean's books she talks about how calcium and magnesium are antagonists when taken together -- they compete with one another.

All I know is that one day I took a calcium supplement at the same time as my magnesium supplement, and shortly afterwards got a migraine.  All I can think is that my magnesium didn't absorb all the way like it usually does.  After that I never took calcium and magnesium at the same time, and haven't had a problem since.
