Bests & Worsts Reviews from Amazon

+ Many forms require adequate stomach acid, this one does not. + Not Buffered - Some magnesium bisglycinate on the market is “buffered”, which usually means that magnesium oxide has been “mixed in” with the magnesium bisglycinate. This makes the product cheaper but also less absorbed and useful, and unfortunately, companies often won’t mention whether or not they are using a “buffered” form. Doctors Best says its unbuffered. + 100mg ELEMENTAL magnesium per tablet. Many brands state the amount of magnesium glycinate/bisglycinate, but not the amount of absorbable elemental magnesium. Magnesium Bisglycinate unbuffered in a pure form has about 14% of 'elemental' magnesium. + Bonded to Glycine for better Absorption without GI discomfort, the bond is easily broken so the body can get to and use the magnesium. Some forms no matter how much you take, the body is barely able to break the bond and use it. + Rated by labdoor to contain low metals. - Tablets may be a bit large for some. See photo vs the smallest Bioschwartz Magnesium Bisglycinate. That is one option although the elemental magnesium per capsule is around 1/4 of that of a DB tablet. Or a Magnesium Chloride Oil to be absorbed through the skin. - Magnesium Stearate and Stearic Acid Magnesium can’t just be by itself as a molecule, it has to be bound to something else to be stable. The biggest difference in different magnesium products is not from the magnesium itself (which is all the same) but from the molecule its bonded to. If you are taking your magnesium in a form where the bond is hard to break such as Magnesium Oxide, then you might as well be taking nothing at all because most will just pass right through you. In other words, it is like there is crazy glue holding the magnesium to its carrier, and if your body can't break the bond, then you won't absorb much if any. Magnesium Bisglycinate is bonded to Glycine which allows the Magnesium to more effectively pass through the intestine. This allows for maximum absorption of what you take without the digestive discomfort generally associated with Magnesium supplementation. The bond in this form is easily broken so the body can get to the magnesium and therefore makes a good option for a supplement. The other part - Glycine is a relaxant, so it may work well for anxiety. The amount stated per tablet is 100mg Elemental. Many times the amount stated per capsule is the amount of magnesium bisglycinate chelate it has, and NOT the amount of elemental magnesium it has. Magnesium Bisglycinate unbuffered in a pure form has about 14% of absorbable 'elemental' magnesium. In other words, they would need around 1429mgs, almost 1 1/2 grams of magnesium bisglycinate in two pills to attain 200mg of elemental magnesium as in two tablets here of doctors best.Taking 520 of Magnesium Chloride will have around 62mg elemental so always know the amount of elemental you are getting, and consider the absorption rate of the form, as some forms like oxide may only absorb 4% of the elemental you take in and require stomach acid so may not be very useful. Magnesium needs Vitamin B6 to enter the cell, and Vitamin B6 needs Magnesium, Zinc, and Vitamin B2 to convert to its active form. So those low on mag for awhile might want to consider adding some P5P (active form of B6 that wont require conversion for the body to use). Boron enhances the body's ability to use calcium, magnesium, as well as vitamin D and helps to prevent calcium and magnesium from being lost in the urine. Around 3mg/day such as pure encapsulations (no filler) or life extension if you dont eat boron foods regularly. Magnesium will detox cells so you might need to increase slowly if you have been low awhile. The vast majority of people are deficient in magnesium due to factors such as the presence of heavy metals like mercury or aluminum, Sugar and Phytic Acid in nuts, grains and legumes both increase Mag elimination, caffeine, alcohol, cannabis, Vitamin D taken in excess lowers magnesium as well also vitamin a and potassium, heavy sweating such as endurance sports, night sweats, hot flashes, phosphates in sodas, deli meats, cereals bind to mag. Wifi and EMF also do as well. For the money, this seems to be one of the better options unless you wish to pay a higher price for no fillers from pure encapsulations which also has a good metal rating.
