Magnesium L-Threonate 500mg Magnesium Supplement Vegan Capsules Bioavailable Magnesium (190 Capsules)

the L threonate version is great for brain as it can cross the blood brain barrier to supply the brain with magnesium as a priority. I don't find it helps with sleep, so I add in other versions of magnesium at night time. This is a good quality product and I purchased the 190 capsule pack, only issue was the short date didn't cover 6 months if taking one per day, so i knocked off a star for that. Will purchase again though
