Sports Research is a great brand for Magtein Magnesium L-Threonate. I always take this brand and it works well. I am pleased with the results. I would recommend and I would purchase again.

I’ve struggled with insomnia for years and have tried so many different supplements with little to no success. After taking Sports Research® Magnesium L-Threonate, I finally noticed a real difference. My sleep feels deeper, and I fall asleep faster instead of lying awake for hours. I also wake up feeling more rested and less groggy, which has been a huge plus. The capsules are easy to take, and I haven’t experienced any negative side effects. If you’ve been dealing with long-term sleep issues like I have, this is definitely worth trying. It’s been a game changer for me.

Very relaxing and calmed the anxiety that came with peri-menopause, I use the Magnesium Glycinate and the L-Threonate together at bedtime and it’s made a huge difference in mood and sleep!! I love that Sports Research is such a clean brand!!!

This Magnesium Threonate uses the same basic Magtein formula, but has fewer additives and is much more absorbable. If you open the capsule into a glass of water, it dissolves, unlike other brands which clump and float on the surface. The taste of the Sports Research product is neutral and there is just a faint odor of rice powder. The Sports Research product is superior to the other brands I have used. Sports Research Magnesium L-Threonate is my new source of Magnesium. Thank you for making such a good product. Highly recommended and will be buying again. 5 Stars.
