Best to take it with Calcium, and best to use capsules over tablets.

In order by price, roughly:

1. Magnesium Sulfate (Epsom Salt)-- serious laxative, can be used externally as a soak, ridiculously cheap
2. Magnesium Oxide -- serious laxative, poor absorption (4%), pro-oxidant, cheap
3. Magnesium Citrate -- serious laxative, cheap (half the price anything below)
4. Magnesium Oratate -- being neutrally charged, it passes easily through cell membranes; not commonly available in capsules
5. Magnesium Aspartate -- possible neurotoxin
6. Magnesium Glycinate -- good price; non-laxative; contains glycine, a neurotransmitter that improves sleep
7. Magnesium Fumerate -- good price; non-laxative; contains fumaric acid, which is brain protective
8. Magnesium Malate -- good price; non-laxative; contains malic acid, which chelates aluminum from the body
9. Magnesium Chloride -- expensive, not commonly available in capsules
10. Magnesium Taurate -- expensive, contains taurine, which is good for the heart
11. Magnesium 2-AEP -- expensive
12. Magnesium Threonate -- very expensive, goes through the blood-brain barrier,
13. Magnesium butyrate -- very expensive
14. Magnesium caprylate -- very expensive

How about Magnesium ascorbate? Plus you missed magnesium glycinate which you can get a good deal on at Swanson’s. Chelated in the best way and won’t give you the runs
