Magnesium Glycinate is the magnesium salt of a compound called glycine—which is an amino acid. Common variations of of this form are magnesium diglycinate and magnesium bisglycinate. These forms of magnesium are commonly found in ‘chelated’ magnesium products, and are the all-around most easily absorbale for your body. Magnesium Glycinate is often recommended by health professionals to patients that are seeking to raise magnesium serum levels for treatment of Hypomagnesemia—the clinical term for magnesium deficiency. Magnesium Glycinate is much less dependent on the acidity levels of the stomach, and is thought to be absorbed by the body through channels utilized by amino acid absorption. If you are suffering from a known magnesium deficiency, magnesium glycinate is usually the best option to help correct that quickly, since it has a fairly high bowel tolerance level. If you’re looking for a type of magnesium that doesn’t cause diarrhea, this is likely your best option for oral use.
Magnesium Taurate
Magnesium Taurate
Magnesium taurate is a form of elemental magnesium that has been combine with an amino acid called Taurine. Taurine is thought to be one of the most beneficial elements in helping to promote longer lifespans. Research has shown that Taurine in itself has been able to reduce the risk of heart attacks by up to 80%, balance electrolyte levels, and promote healthy immune function.13 Additionally, magnesium taurate supplements have demonstrated the ability to treat cases of depression 14, vascular health, and the prevention of neurodegenerative disorders and migraines.15 in clinical settings. Magnesium Taurate can be slightly more difficult to find than other forms of magnesium, but with the rising demand among health-conscious buyers—it is becoming more available. L-Taurine is also considered to be a powerful nootropic compound, capable of improving overall cognitive function and memory. This close association of magnesium taruate and taurine lead many to believe magnesium taurate to be one of the better suited magnesium supplements for brain health

I've read other places that magnesium taurate is only 10% magnesium so in addition to it's higher cost you have to take more of it to get the same amount found in other supplements. There are dozens of different types of magnesium. Many of which are not easily absorbed by the body. Magnesium oil is supposed to be very good but you need to spray it on yourself after you get out of the shower. Supposedly it works even better than Epsom salt which is another form of magnesium that people used to soak their feet in and can be used like magnesium oil though it's not quite as good. Neither one is very good to take internally because they are not very absorbable and cause diarrhea but if you're looking for a laxative then that might not be such a bad idea. All forms of magnesium are laxatives but some kind are way more than others.
