Magnesium L-Threonate
Momentous uses Magtein, the only form of magnesium clinically shown to effectively cross the blood-brain barrier. It is ideal for those who want both cognitive benefits and improved sleep quality without any digestive side effects.
Ingredients & Purity
Features 2,000mg of Magtein (providing 144mg of elemental magnesium). This form is specifically chelated to threonic acid.
Scientific Evidence
Clinical trials on Magtein show improved synapse density. While evidence for sleep specifically is emerging compared to glycinate, users report high success with 'brain-calming' before bed.
Brand Transparency
Extremely transparent with third-party testing results. Part of the 'Huberman Lab' partner brand list, emphasizing science-first formulations.
Value Assessment
This is a very expensive supplement ($1.80+ per serving). It is only recommended for those who do not respond well to cheaper magnesium forms or want the cognitive crossover benefits.
Why Not Alternatives?
While other brands use Magtein, Momentous is one of the few that subjects the finished product to rigorous NSF Certified for Sport and Informed Sport testing. This ensures the highest level of purity compared to cheaper Magtein sources on Amazon.
