Sleeping better

I use Vitacost Magnesium Threonate to sleep peacefully at night. The quality is equal to higher priced L-Threonate. The capsules are easy to swallow. I will also take one when I wake at 2am. Helps me return to sleep in 20 minutes instead of one hour.

Magtein L-Magnesium Threonate

I had been taking Magnesium Glycinate but it was not helping with sleep quality and quantity. Since I changed to L-Magnesium Threonate, I've been getting 7-8 hours of good quality sleep.

My Va Dr. told me to use this to help some of my vietnam veteran conditions, and it has helped. But the cost of it is sometimes an issue. I take two a day.
