Magnesium L-Threonate

Momentous uses Magtein® Magnesium L-Threonate, the only form of magnesium shown to effectively cross the blood-brain barrier and support brain health.

It helps with sleep quality, memory, and cognitive function without the digestive issues that come with other forms of magnesium. Take it about 30-60 minutes before bed, and it helps your brain actually calm down for quality rest.

It’s ideal for individuals looking to improve focus, reduce stress, and support deep, restorative sleep without sedation.
