Review: I have been taking this for quite some time. It definitely helps with sleep. I think it also makes me have less brain fog when I wake up but that might be a side product of better sleep. Its definitely better for the cognitive function. Everything else is harder to detect. It is worth the money for me. EDIT* I also get leg cramps when I forget to take mine at night - definite sign of magnesium deficiency. It does the job with no side effects. Review: This magnesium is awesome. I do recommend taking before bed because it puts me in a state of relaxation. Highly recommend. ## Features - Vegan Formulated - Manufactured Without Gluten, GMOs, Additives, Preservatives, Artificial Colors, Soy, and Dairy.

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 ### ⭐⭐⭐⭐⭐ Review *by J***R on 4 November 2024* I have been taking this for quite some time.
