Single ingredient, no additives, no unpleasant taste
I have been trying to figure out for a while, how to improve my magnesium intake with a higher quality version of magnesium than my default, magnesium oxide, which has evidence for such poor absorption. I read that magnesium three and eight can cross the blood brain barrier and can be helpful for a brain health. I’m hoping I will see some positive results, but even if I don’t, I appreciate being able to take such a pure form of magnesium with the benefit profile that I am looking for. I hope overtime it might help with sleep quality and duration.
