The most common question I’m asked about magnesium is “What form of magnesium should I be taking?”    In other words,

What type or form of magnesium is best?   Which form of magnesium is best absorbed?  Which is most bioavailable?


I always answer:


“The research, which I’ve been studying since 1985, tells me over and over that it’s not the form of magnesium that’s important but the dose.   Meta-analysis studies gathering several clinical trials of magnesium for certain conditions, like high blood pressure, show us that the form of magnesium is not what really matters – what really matters is the daily dose of magnesium given.

How much elemental magnesium is in your daily oral supplement?

250 – 500 mg per day if you are very healthy and have a really good diet that is high in micronutrients (vitamins and minerals) including magnesium

600 – 800 mg per day if you are showing any signs of a magnesium deficit:  high blood pressure, high cholesterol, high fasting blood glucose, or if you have none of these but engage regularly in vigorous exercise

800+ mg per day plus transdermal magnesium daily if you have a chronic condition that is magnesium related:  afib, mitral valve prolapse, osteoporosis, copd, depression, cardiovascular disease, or are healing from an operation, illness or have had a recent trauma.

IN all cases, if your GI tract is not comfortable with the high levels of oral magnesium, give a transdermal magnesium a try.   Getting a whole-body massage with Magnify magnesium cream mixed with cocoanut oil or other massage lotion can really do wonders for someone with a magnesium deficit.
