A few years ago I did a lot of research and went with Magnesium Glycinate 400mg and it ended up raising my blood pressure. Totally disappointed, but my body reacts strangely sometimes to things most people don't have a problem with.


IIRC, this guy was pretty helpful.

I use their L-Threonate and they're coated, so it doesn't mean that these are uncoated.

FYI, these tablets are big and a PITA to swallow. We ended up switching to Magnesium Glycinate capsules from another brand because we kept choking on these tablets.

There's a product called ReMag, it's ionic magnesium, absorption is much better than this.

Magnesium - Health Professional Fact Sheet [nih.gov] is an article by the NIH. When I was researching magnesium I learned that most magnesium supplements provide much more magnesium than we need. These magnesium supplements are only 100 mg and that is less than the recommended amount. Therefore it is good that it is not more than what we need. Look at Table 1 in that NIH article; the recommended amount varies by age. In Dietary supplements the article says:
Quote :
Small studies have found that magnesium in the aspartate, citrate, lactate, and chloride forms is absorbed more completely and is more bioavailable than magnesium oxide and magnesium sulfate
Something else that is interesting is that (if I understand what they are saying) testing blood for magnesium is not reliable. Therefore perhaps the doctors might not know if you have a magnesium deficiency.


For very many years I have had a problem getting to sleep. I learned that a magnesium deficiency can cause sleep problems. I have been taking magnesium for a few months and doing much better at getting to sleep than I have for decades.
