The Active Ingredient Is: Magnesium (L-Threonate Form)

Magnesium L-Threonate is a mineral salt crafted for higher brain bioavailability and supporting normal nervous system function and relaxation, which adds a friendlier tone.

This form is chosen for its potential to deliver magnesium to the brain, and helps to support healthy sleep-related processes and cognitive calm as part of a sleep support formulation, which feels more down-to-earth.

What Does Magnesium (L-Threonate Form) Do?

Magnesium plays a role in the normal functioning of nerves and muscle calmness, contributing to relaxation that supports normal sleep onset and maintenance, which helps you settle in.

It helps regulate nervous system activity and supports pathways involved in calming the mind, with absorption-enhancing effects improved by the formulation to support everyday sleep-related physiology, and this makes mornings feel easier.
