Why we started

No harmful fillers, from day one.

Dr. CC, PhD, developed our formulas from over 25 years of experience in natural medicine. The manufacturers she approached considered fillers like synthetic silicon dioxide and magnesium stearate a normal part of making supplements. She researched them and decided not to compromise, finding her own way to maintain quality without artificial ingredients.
