This is essential for most adults. Unless you’re suffering from constipation and just need Magnesium Citrate, I prefer this blend over any I’ve seen. It has MG Malate, L Threonate, and Glycinate. I think these are the three that are needed for uses in the brain.

Ingredients:
Magnesium 200 mg (as di-magnesium malate, magnesium L-threanate, and magnesium lysinate glycinate chelate)
