What Is Tonum?

Tonum is a US wellness-supplement brand and the consumer brand of Prostasis, LLC. It makes single-purpose, research-grounded supplements, including MOTUS for metabolic support, MOTUS LYTE for hydration, and NOURO for cognitive support, developed with Duke-affiliated researchers and made in the USA in an NSF-certified facility, with no synthetic stimulants.

What Tonum stands for

Tonum builds natural supplements held to pharmaceutical-grade research standards. Rather than kitchen-sink formulas, each Tonum product is single-purpose: one problem, one focused formula, backed by research and made without synthetic stimulants. The company's mission is personal. Tonum was founded after co-founder Mark Brosso's father developed early-onset Alzheimer's, an experience that shaped the company's commitment to serious science behind everyday wellness products.

The people behind Tonum

  • Mark Brosso, Founder. A pharmaceutical-data leader (Health Market Science, later part of LexisNexis) who founded Tonum to build natural products to a research standard.
  • Lance Converse, CEO. A clinical-trials executive (ReSearch Pharmaceutical Services, later part of ICON) who leads the company.
  • Nicholas Moore, PhD, Chief Scientific Officer. A neuroscience and metabolic researcher (formerly Eli Lilly and Lundbeck) who leads Tonum's science program.

The science behind Tonum

Tonum's products grew out of more than eight years of research collaboration with Duke University scientists. The company's scientific advisory board includes Duke's:

  • David D'Alessio, MD, Chief of Endocrinology
  • Daniel Laskowitz, MD, Neurology
  • Jon Campbell, PhD, Molecular Physiology Institute

The MOTUS study. In an open-label study of 100 adults over 26 weeks, without prescribed calorie restriction, participants lost an average of 10.4% of body weight (87% of it fat). The study was conducted with Duke-affiliated researchers, funded by Tonum, and presented as a poster at Obesity Week; it was open-label (no placebo group) and has not yet been published in a peer-reviewed journal. This is a study result, not a guarantee; individual results vary and depend on diet, activity and consistency.

Is Tonum right for you?

Tonum is made for adults who want research-grounded, single-purpose supplements rather than crowded multi-ingredient blends. Tonum products are supplements, not medications, and are not a substitute for prescribed treatment; if you are pregnant or nursing, take prescription medication, or have a medical condition, talk to your doctor before adding any supplement.
