As magnesium L-threonate is relatively new, the book does not discuss its percent of elemental magnesium, but by subtraction, it should be about 68mg elemental magnesium from magnesium L-threonate, or about 7%. In other words, each of the three forms of magnesium provides about one-third of the total 200mg elemental magnesium in one serving (three tablets) of the product. **Q: For manufacturer: How many MG's of elemental magnesium for the three types of magnesium per serving?** A: 200 MG from 3 tablets **Q: How many mg of elemental magnesium are supplied by each type of magnesium per each cap? i need the seller or manufacturer to respond. unclear label.** A: It only states per serving of 3. It doesn’t list the individual pill. **Q: What's the expiration date?** A: The expiration date on my bottle is 03/2020 ## Customer Reviews ### ⭐⭐⭐⭐⭐ High quality magnesium *by E***R on May 4, 2025* This magnesium is awesome.
