Effective results
Size: 90 Count (Pack of 1)
This is the only supplement I take where I actually feel its effects. It helps regulate my sleep, helps brain function and anxiety, just makes me feel better overall! And it’s not rough on the stomach at all. Highly recommend!

Noticeable Support for Calm and Clarity
Size: 90 Count (Pack of 1), Size: 90 Count (Pack of 1)
This magnesium L‑threonate supplement has been a great addition to my daily routine. The capsules are easy to take, gentle on my stomach, and I’ve noticed a clearer, more focused feeling throughout the day. It also brings a nice sense of calm in the evenings without making me groggy. The formula feels clean and well made, and it fits effortlessly into a wellness routine. If you’re looking for a reliable magnesium option that supports relaxation and mental clarity, this one is a solid choice.

Highly recommend for sleep, mood, mental health
Size: 90 Count (Pack of 1)
I recently re-discovered this supplement, and I'm buying extras left and right and recommending to everyone I talk to. I've been working on increasing my HRV and supporting my nervous system, and the L-threonate is a rockstar for that. I was taking glycinate for a few months, and I found an old bottle of this one and added just 2 capsules, and the effect on my sleep was immediate. Way better than melatonin. My Fitbit is tracking much lower restlessness and more deep sleep, and I actually wake up feeling refreshed ?? and before my alarm, even! I'm noticing lower anxiety and an overall better mood, and it's only been 4 days. This bottle definitely holds its value, and the price is good, especially if I can get these benefits with just the 2 caps and not 3.

Big winner for helping BETTER SLEEP
Size: 90 Count (Pack of 1)
Life Extension is top of the line on most things they have. also pricier than most, but I buy three items for them regularly for many years. This Neuro-Mag with L-Threonate is excellent for boosting better sleep. This is a newer addition to their line. I also suggest trying their Mult-B complex and their B-12 elite (sublingual) On nearly all items, their quality control is near THE TOP of all suppliers. They also have supported vitamin and supplement research on my items over the last 40 years

Energy and Clear Thinking
Size: 90 Count (Pack of 1)
Great product. I use various forms of magnesium for different things . This form was suggested for clearer thinking and energy, and it delivers! I use it in the AM and it helps keep me energized I do think it varies by person how it affects you though as some folks get drowsy w/ it. Just a heads up to test on a weekend perhaps. I won't be without it now!
