Better sleep, better mood
This definitely helped my mood and sleeping. It literally changed my default. The only electrolyte that can pass the blood brain barrier. I recommend.

Not working for me 100%
Still not sure about how this magnesium affects me. I have only been taking one tablet an hour or two before bedtime. Seems like sometimes I can’t go to sleep after taking it, charges up my brain. Other times I sleep but have crazy dreams. Maybe it works for some, but not others. I’ll try to finish the bottle, but the lack of sleep after taking the Magnesium L-Threonate makes me hesitant to continue some nights. That’s mainly the reason I purchased this brand to include the reviews.

very good
Format: Kindle
Another good addition to this publisher's collection. The book is well organized, flows well and is very readable. The main thing I have like about this series is that they don't just cover the "highlights," although they do a good job on those, but how they cover more of the daily lives of the people. I was surprised at exactly how hard the people's lives were by choice, not just men but woman as well. I can't imagine being drafted into the military at age 5 or 6 and staying there until you were thirty. And eating "black soup" a concoction made of pork, pigs' blood, onions, salt and vinegar. To paraphrase a quote, it's no wonder Spartans were prepared to die when all you eat was this soup! I was also surprised by the freedoms including education and land ownership of the woman of Sparta giving the era.....and the sexual freedom they had was more surprising. There is a lot more information of interest. This is a good book and most will enjoy reading it
