Overview
Momentous markets this as a magnesium L-threonate, or Magtein, supplement built around cognitive function and sleep quality claims. It's NSF Certified for Sport, a third-party program some athletes look for to check that a supplement's label matches its contents and screens for banned substances.
At around 717 reviews and a 4.6 average, the feedback base is smaller than mass-market magnesium oxide or citrate products, which fits a specialty ingredient with a narrower audience and a higher price point.
Priced near 50 dollars for a 30 serving bottle, this is one of the pricier magnesium options in the lineup, reflecting both the L-threonate form and the NSF Certified for Sport testing the brand highlights.

Performance notes
The L-threonate form and NSF Certified for Sport label point this product at a specific audience, namely athletes or anyone specifically seeking the Magtein ingredient rather than a general magnesium supplement. The 30 serving count means it's a shorter-term bottle compared to the 90 to 240 count options common elsewhere in this category.
What buyers say
With 717 reviews at a 4.6 average, sentiment is positive but the sample is smaller than many higher volume magnesium listings, consistent with a specialty, higher-priced product.

Frequently asked questions
What is magnesium L-threonate, or Magtein?
It's a specific chelated form of magnesium that the maker markets for cognitive function and sleep quality support. As with any supplement claim, talk to a healthcare professional if you have questions about which form fits your needs.
What does NSF Certified for Sport mean?
It's a third-party certification program that tests supplements for label accuracy and screens for substances banned in many sports. Momentous highlights this certification on the label.
How long does one bottle last?
The bottle is sized for 30 servings, so it's a shorter supply than many 60 to 240 count magnesium bottles, which is worth factoring into the per-serving cost.
