After consulting with hundreds of patients, I am seeing a scary pattern that I want to bring to your attention.
The concern is the combination of rock bottom intracellular magnesium “and” low vitamin D levels.
It is important to know that if you have a low vitamin D level in spite of taking it, a magnesium deficiency can be one of the reasons you can’t correct it.
Magnesium levels in the first quintile (lower 20% of reference range) or below that, could make you a victim of a fatal heart attack.
The following represents the quintile ranking. You want to see your intracellular magnesium in the 5th quintile.
In addition to increasing your intracellular magnesium levels to the 5th quintile, I recommend working on increasing your vitamin D levels to 75 nmol/L or more.
Don’t accept a level of less than 50 nmol/L. It is simply insufficient to support good health. The most current medical literature has shown that 5000IU per day is safe. You can even go as high as 10,000 IU.
It is sad to see that many physicians are still recommending 400IU per day. This is out-dated information. This level is only for preventing a disease called rickets.
Much higher levels of vitamin D are needed for prevention and healing diseases such as diabetes, coronary artery disease, osteoporosis, depression, recurrent infections, dental problems, etc.
So the take away is make sure you have your physician test your intracellular magnesium levels in conjunction with vitamin D levels.
By the way, I mean intracellular NOT serum magnesium. This is commonly ordered on a basic blood test.
The following are two good labs that offer the intracellular magnesium:
