Clinically proven weight & fat loss*, naturally

Motus is a natural supplement that helps burn fat, not muscle, giving you the energy to reach your goals

*In a 6-month human clinical study, participants lost an average of 10.4% of body weight

How motus works

Targets fat — not muscle.

Motus supports metabolic pathways involved in fat utilization while helping preserve lean muscle mass, so weight loss comes from fat — not strength.

Increases energy

By supporting how your body produces and uses energy, Motus helps promote steady, sustained energy throughout the day — without sharp peaks or crashes.

Reduces food noise

Motus helps support balanced hunger and fullness signaling, making it easier to stay aligned with your goals without constant cravings or mental distraction around food.

Real people. Real progress.

Founded in research.
Inspired by love.

Our founder, Mark Brosso, started Tonum with a deeply personal mission.


In the same week, both his father and young son were diagnosed with serious neurodegenerative conditions. In search of answers, Mark turned to Alzheimer’s and metabolic science — where he uncovered a critical insight: the metabolic pathways linked to neurodegeneration also play a key role in fat loss, energy, and metabolic health.


That discovery led to Motus, which was refined over eight years through extensive research and human clinical studies.


Today, Mark’s son is a healthy young adult, and Motus continues to reflect its founding mission: using science to protect long-term health, strength, and longevity.
