Great product, helps me to sleep

Higher quality than I realized.
I often load screenshots of Supplement labels to Chat GPT for an analysis, before or after buying.I did that with This one and then spent sometime drilling down on it.Chat GPT gave it a very favorable review, even saying that this manufacturer has a sophisticated understanding of how different magnesiums work in the body.I bought this one for the L-Threonate, but it turns out that it also provides Glycinate anf Malate which combine to cover a spectrum of physiological needs. ChatGPT was also complimentary of the Magtein for; Testing, Human Reaearch, and Manufacturing specs.I’m very pleased with this and will order again when I run low.

The Best Magnesium for My Brain and Sleep – A Nighttime Essential
I started using Magnesium L-Threonate because I was looking for something that truly supports brain health and improves sleep quality, and I can honestly say it has become an essential part of my routine. This form of magnesium is known for its ability to cross the blood-brain barrier, which means it works directly on the brain, helping with memory, focus, mental clarity, and relaxation.One thing I really like is the capsule size. The capsules are easy to swallow, not big or uncomfortable at all. That makes a huge difference for me when taking supplements daily.I always take it at night, right before going to sleep, and I can feel my body naturally winding down. My sleep feels deeper, I wake up less during the night, and I feel more rested the next day. I also notice an overall sense of calm, as if my mind can relax more easily.If you’re looking for a magnesium supplement that goes beyond the basics and truly supports both brain health and sleep, this is one of the best I’ve ever used. I highly recommend it and will definitely keep it as part of my nightly routine.

Love it, check for interactions
Love this! However make sure to review all medication/vitamins you are taking. I take synthroid and the interaction if taken within 4 hrs of each other, caused my heart to flutter, chest pain, and headaches. Also if taken with blood pressure meds it can cause adverse reactions. I WILL SAY, IT IS AMAZING AT HELPING WITH BRAIN FOG, SLEEP, AND ALERTNESS! I LOVE IT WISH I COULD TAKE IT STILL.

Great combo. It’s exactly what I needed
This is the best oral version of magnesium I have found. The different types within it have really helped me to recover long-depleted minerals. Taking dose at night before bed has calmed restless tingly legs beautifully. This has been in my supplement daily regimen for two years now and I have no plans for changing it.

Yes it’s excellent and my Dr approved it. Take one in the morning and one at night fall asleep fast.

Brain Fog Improvement and Better Sleep!
Brain fog is gone. I have been using this supplement for 30 days, and I’ve noticed a significant improvement with brain fog and memory. This magnesium supplement has greatly improved my sleep quality as well.I started taking this for sleep, but I’ve noticed my focus and memory has improved as an added bonus. I have tried several magnesium supplements, and this is by far the most effective. I will continue to use this supplement. 5 stars! ⭐️
