Review: Magtein at the best price and it works well. Love the flip top bottle. Just an all around great staple supplement and brand.
Review: I’ve been taking these Sports Research Magnesium L-Threonate capsules for about 4 months now, and they are honestly amazing. I originally bought them to help with sleep, and they’ve made a huge difference — I fall asleep easier, stay asleep longer, and wake up feeling more rested instead of groggy. What I didn’t expect was how much they would also improve my mood. Since taking these consistently, I feel calmer, more balanced, and less stressed throughout the day. It really feels like my brain and body just function better on this form of magnesium. This formula absorbs well, doesn’t upset my stomach, and the capsules are easy to take. I’ve tried other types of magnesium, but none of them have worked nearly as well as Magtein. If you’re looking for something to support sleep, focus, or mood, I highly recommend giving these a try. They’ve made a noticeable difference for me, and I’ll definitely keep taking them!

## Features

- HIGHLY BIOAVAILABLE FORM: Magnesium L-threonate is the salt formed from mixing magnesium and threonic acid, a water-soluble substance derived from the metabolic breakdown of vitamin C. Easily absorbed, our magnesium L threonate capsules are used for their overall brain health benefits and may help support memory, focus, relaxation, mood, and cognition.
- MADE WITH MAGTEIN: Magtein is a patented compound called threonic acid developed by a group of MIT researchers. Magtein is the only form that effectively crosses the blood-brain barrier and increases magnesium levels in the brain, which is critical for improving cognitive function.

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!!!
