I recently had my b12 and magnesium and vitamin D levels checked and my doctors just say they are ''normal'' nothing else. But I really don't think so. I read online that checking for certain vitamins/minerals levels they can't be reliable because for example, during high stress magnesium is released into the blood, so you have more magnesium in your blood but less in your cells or bones or tissues etc, now this would make it seem like you have high magnesium but that's not the case just that your body is using up more but in turn your cells and bones and tissues are deprived of magnesium and your body starts to deteriorate overtime. That is just with magnesium, what about all those other vitamins & minerals? So you would have to ask for a specific way for them to test your magnesium.
Since magnesium is an electrolyte, a magnesium test may be ordered along with other electrolytes such as sodium, potassium, chloride, bicarbonate (or total CO2), calcium, and phosphorus to evaluate a person's electrolyte balance. If magnesium is low, it is not unusual for potassium also to be low. Normal levels of magnesium do not necessarily reflect total body stores of magnesium. The body attempts to keep blood magnesium levels relatively stable and will release magnesium from bone and tissues to accomplish this.
So, the blood level may be normal with early magnesium deficiencies.
See this quote from WEBMD:
Other Magnesium Tests
Some experts don’t think a blood test is the best way to find out your magnesium level. That’s because much of the magnesium in your body is stored in your bones and other places, not in the blood.
Stress can send magnesium out of your cells and into your blood. This can make it seem like you have more magnesium in your body than you really have if you simply have a blood test.
There are other tests. Some of them:
- Test how much magnesium you get rid of in your pee.
- Test the level of magnesium in your red blood cells (RBC).
- Test the magnesium in your cells, not in your blood. This test is known as an “EXA Test,” and is done through a sample of your mouth cells. It is not easy to get this test because it is not commonly known and it is very expensive.
- Add magnesium to your blood, then see how much goes into your urine
So obviously, I have a lot of anxiety, so it is making it seem like I have more magnesium in my blood than I really have. So what/how should I ask them to check for my magnesium levels? Should I do the magnesium in my red blood cells test or pee?
Also, what other vitamins & minerals should I have to worry about or re-test again because they can be misguided like with magnesium? Is it possibly b12 and vitamin D also have this error in the blood testing? thanks for any help is greatly appreciated.
I was thinking of using magnesium topically, how effective are those absorbed?
