Quality & Materials

Features 2,000mg of Magtein (providing 144mg elemental magnesium). Free from unnecessary stearates and flow agents.

Evidence & Testing

Clinical trials on Magtein show significant improvements in executive function and sleep quality by increasing brain magnesium levels more effectively than other forms.

Brand Transparency

Every batch is third-party tested for purity, potency, and heavy metals. Certificates of Analysis (COAs) are accessible upon request.

Value Assessment

This is a premium product with a high price point ($1.50+ per serving), making it a 'performance' choice rather than a budget one.

Why Not Alternatives?

While many brands sell Magtein, Momentous distinguishes itself through rigorous third-party testing (Informed Sport) and a partnership with the Huberman Lab, ensuring the protocol is based on current neurobiological research rather than marketing trends.
