Stellar Brand, Stellar Threonate

This is some expensive vitamin but given the vast health benefits of magnesium for a variety of for coenzymatic process in the human body, we now know from the latest literature that magnesium is not a supplement we want to be frugal on because there is such significant ROI. I would definitely recommend these to anyone feeling antsy or overly excited in a sort of stressed out way. It’s a great way to calm the muscles in the mind directly and improve focus through it’s ability to pass the blood brain barrier. It sure is pricey(like other brands) but your attention, sleep, and mood will all improve. I went with double wood as their reputation as an supplement seller is already stellar, and this supplement is the same way.

Cool and level headed

This was my first time trying magnesium l-threonate. I had supplemented other types of mag, so I wanted to see if it had an affect on the brain. From what I gathered, to those who are low on magnesium will notice some reaction and feel some calmness in the mind. Mind you, it's best to take at least before you go to bed, as I think it works great to rest the brain and recharge for the next day.

Noticed a Real Shift

I’ve been using this to help with sleep and focus, especially with ADHD challenges, and it’s honestly helped. I feel less scattered during the day and more mentally settled at night.It doesn’t knock me out or make me feel groggy, but it does help me wind down and stay on track without the usual mental fog. My thoughts feel clearer, and I’m not as easily distracted.No weird side effects, and it’s gentle on my stomach. I like that this uses Magtein, it’s supposed to be the most effective form for cognitive support, and I can see why.A little pricier than basic magnesium, but if focus and mental clarity are your goals, it’s worth it.

deep sleep. stress reduction

Health care provider suggested this specific form of Magnesium. 1st time using clear benefit and after 5 days using continued sustained help. Still use with my other Magnesium supplement too. However, this form of Magnesium taken 1-2 hours before sleep time enhances a deep sleep thru the entire night. if do wake up, no problem returning to that previous deep sleep state. Wake mentally refreshed and have the internal drive to do things (due to correct sleep) that otherwise no ability or interest in doing. Stress or worry is totally gone. Makes you feel great and if already great fantastic.
