One of the things that stood out to me about this supplement is the high absorption rate and bioavailable form of magnesium, which makes it more effective than other forms of magnesium. I have been taking it regularly, and I have noticed an improvement in my cognitive function, and it also helped me with my sleep.
The 2,000mg per serving and 100 capsules per bottle are enough to last for a good while, especially considering that it is recommended to take 2 capsules per serving. The price is also very reasonable and I feel like I'm getting good value for my money.
Overall, I highly recommend this Magnesium L-Threonate supplement to anyone looking for a high-absorption and bioavailable form of magnesium for cognitive and sleep support.
I just have to say this stuff is a miracle!!! The headaches have stopped. I still wake up in the middle of the night, but I’m able to return to sleep quickly. The hot flashes have also reduced greatly. I used to have 3-4 per night, and now I’m down to 1 or none! But the biggest surprise is something else. I’m remembering things from years ago that I hadn’t thought of in decades. Completely random memories. My dreams are now extremely vivid and some of these memories are actually happening in my sleep. I even remembered a dream I had about 10 years ago while I was dreaming! And I solved a complicated IT problem we were having at work that no one else could figure out, all while sleeping. I don’t know how this stuff works, but it just does. I’m only taking 2 capsules per night in combination with 2-3 capsules of Double Wood’s Magnesium Glycinate, which is another excellent product. These two supplements have literally changed my life. I used to be loyal to Pure Encapsulations, but now I’m realizing that brand has done nothing for me all these years. I don’t know if Double Wood’s is more potent or pure, or if the capsules just break down better in my body to access the magnesium, but the results have been way better for me compared to Pure Encapsulations. My sleep is incredible, no more headaches, not as many hot flashes, better memory, and other random benefits - no more heart palpitations/pounding at night, way less anxiety, overall sense of calm, and increased level of happiness. I can’t say which magnesium is doing what, but the two together are a powerhouse combo I’m sticking with for life. I can’t say it enough, Double Wood’s magnesium supplements have literally changed my life. Give it a try if other brands have not worked well for you.
Top reviews from other countries

I should have read all the one star reviews before buying this product.
At night after talking 2 capsules, I did fall asleep quite quickly but after about four hours I was awake and was not able to go back to sleep. Furthermore after two days talking the recommended dosage, I developed diarrhea
Did stop using this product after one week and I was back to a good sleep and bowl movements
DISAPPOINTING product



I really recommend and I will order another one.
very good product.
