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!

Capsules Are Too Large and Have a Strong Plastic Smell
Size: 90 Count (Pack of 1)
I’ve purchased this product twice, but the capsule design is a big downside for me.
The capsules are very large and difficult to swallow. On top of that, there is a noticeable plastic-like smell from the capsules, which is quite distracting and unpleasant. It makes taking them every day uncomfortable.
The product itself may work as intended, but the capsule size and odor seriously affect the overall experience. I wish they would improve the capsule material or offer a smaller or odor-free option.
If you are sensitive to smells or have trouble swallowing large capsules, keep this in mind before buying.

Good!
Format: Kindle
I love these books as they are always informative, educational and interesting! Provides the right amount of facts/tidbits - not too little, not too much.
