The challenge with many supplements is that often it is difficult to determine how well they're working. Unless your body is deprived in nutrients, taking vitamins like A, B, C, D-3, E, etc won't change much on the surface despite potentially working wonders on the inside. That is not the case with Magnesium L Threonate. Three things I noticed within days of taking 1000 mg (2 capsules) in the evening: 1) I sleep better. Manage to get 7+ hours every night. If I should awaken, I have no problem getting back to sleep. And the dreams tend to be more interesting. 2) Cognitive function has improved. I feel I can think faster and solve problems quicker. Memory recall is stronger. Especially with names, movie titles, songs, etc. 3) Feel more calm overall. Those moments in life that make one feel anxious or depressed have lessened notably. Highly recommend. (I'm a 56 year old, white male of Eastern European heritage.)

I had heard this works well for anxiety, memory and sleep and does not cause stomach distress. So far both my husband and I have noticed falling asleep quicker and better quality of sleep. I take one capsule during the day and it helps me feel calm and happier. My husband says we are not allowed to run out of it lol. It also is helping my son who struggles with attention, focus, fidgeting etc... none of us have had any digestive issues taking it. I highly recommend this!!

Total knockout, this paired with Ltheanine, and a small amount of zinc = Waking up without a care in the world.

Magnesium L Threonate Capsules (Magtein) - High Absorption Supplement - Most Bioavailable Form - 2,000 mg - 100 CapsulesLove this product! Do you suffer from muscle cramps? Do you have anxiety or trouble sleeping? Do you know anyone that has suffered a traumatic brain injury (T.B.I.)? At one time or another in my life, I have suffered all of these. I went to bed tired and woke up tired. I thought getting older meant feeling terrible all the time. And then I started taking Double Wood Supplements' Magnesium L-Threonate... what a difference it has made!!! I wake up feeling good, nothing hurts and I am ready to jump into my day with no brain fog! I have not felt this good in years. I don't know why more doctors don't recommend these kinds of supplements; they are literally life altering. I take 1-2,000 mg/day and these easy to swallow capsules have a high enough concentrate that I only have to take 2-4 a day. If you struggle with sleep issues, try taking them before going to bed. Since starting these I am getting the best sleep I've had in years! I will be supplementing with these for life.

About a month into my new job I was having a lot of trouble concentrating and just felt kinda “blah”. I wouldn’t say I was depressed but I certainly felt a little empty inside. I thought this was really weird because I was so excited to get my new job. Even though the hours were brutal the pay was much better and it was definitely a step up for my career. Honestly though with these new problems it was pretty hard for me to meet the expectations I set for myself. I decided to schedule an appointment with my doctor and walked him through everything. What he noticed was that I had completely changed my diet. I was so busy now I never really had time to cook for myself. I was eating food on the go and my diet wasn’t balanced at all. I got almost no vegetables/fruit anymore which apparently are very high in magnesium. My Dr. wasn’t 100% sure but he suspected I may be deficient in Magnesium and recommended Magnesium-L-Threonate along with a diet change. He said L-Threonate is absorbed into the body better than any other magnesium supplement out there and can cross the blood brain barrier. If I was indeed deficient in magnesium it would help me quickly. After less than a week of taking it the changes were like night/day. I felt more excited about life and could concentrate much better. In short, I felt like myself again. I don’t know who to thank more, the doctor who accurately identified my problem or this supplement. I am almost done with my first bottle and my second bottle is already on the way. I do plan on fixing my diet and have taken some steps towards doing that but right now I am satisfied with where I am and the way I feel.

I have taken many forms of Magnesium ( glycinate, maleate, citrate) in addition to this formula. It wasn't until I went a few weeks without any Mag Threonate that I noticed my mood, focus and outlook on life was dampened. After reordering this product and taking for a few days, I was back to my old happy self. I am convinced that if you are wanting a Magnesium supplement that helps with many mood and cognitive functions, this is it!! Only downside is price... would be great to have it offered in a bigger bottle!

As far back as I can remember which is like highschool (I am 30 now) I have had sleep issues. Not only would it sometimes take me as long as 30-60 minutes to fall asleep, but almost every night I would wake up every 3 hours. Even though I usually fell back asleep rather quickly some nights I didn’t and it was frustrating to say the least. I’ve tried all sorts of medications like ambien and trazedone. However, they didn’t keep my asleep and I could only take them twice a week at most because you build a tolerance and I was afraid of becoming addicted to them. One day when I was scouring the internet for solutions I came across this. It has been a TREMENDOUS help. I take the full dose with dinner and noticed extreme changes almost immediately. -I feel more tried at night when I want to fall asleep. This has cut down on the time it takes me to fall asleep. Usually I can fall asleep within 10-15 minutes as opposed to 30+ -Instead of waking up every 3 hours nearly every day I now sleep for a solid 6 hours before waking up 5/7 nights a week. And when I do wake up after 6 hours I fall right back asleep. I wish I could give this product 6 stars it has been such a tremendous help to me.

After going to doctors for two years and getting numerous tests done I finally found a neurologist that suggested this product. It has made me feel great. Who would think a little thing like this could make such an impact. Before this I was dizzy, my heart rate was out of control, I would get muscle cramps that would wake me up, and I felt so weak it was hard to stand. As a nurse that is my job to be on my feet all day. This has made all the difference! And I very grateful I hand the energy to do things again.

This is good magnesium l-threonate. I take one serving (4 pills - 2,000mg) an hour before bed. I don't remember the last time I slept so well.

I have a couple of different heart arrhythmias that were into the dangerous range. I tried one prescription medication and it worked for a couple of days, and then quit working and had bad side effects. My Cardiologist suggested I try Magnesium Threonate, since he has had other patients who have been helped by it, and we are trying to avoid me having to have an ablation. So, I bought this, and it works very well for me. I have been taking it for several weeks, and it has greatly lessened my episodes of arrhythmias. And I have only been taking a low dosage so far, because I am always sensitive to anything I take, so I always go slowly. The cardiologist wants me to slowly up my dosage to hopefully totally eradicate the arrhythmias entirely. This product has changed my life for the better in a huge way.
