A formula is only as good as its raw ingredients.
Inconsistent sourcing leads to inconsistent products. That's why we've built long-term relationships with some of the most respected ingredient manufacturers in the world, organizations that invest in research, maintain rigorous quality systems, and stand behind the efficacy of what they produce.

What doesn't make it into our products.
Every ingredient earns its place. If it doesn't serve the formula, it doesn't go in. That's why we're strict about what we formulate without.
Common allergens
We formulate without gluten, soy, dairy, wheat, peanut, tree nut, eggs, fish, and shellfish, unless labeled otherwise.
Artificial colors
When colors are in a formula, they come from natural sources. No synthetic dyes like Red 40, Yellow 5, or Blue 1.
Artificial flavors & sweeteners
No artificial flavors or sweeteners like aspartame, sucralose, or Ace-K.
Artificial preservatives
No synthetic preservatives like BHA, BHT, TBHQ, sodium benzoate, potassium sorbate, or propylparaben.
Microbial pathogens
We screen every batch for microbial contaminants like Salmonella, E. coli, Staph, yeast, and mold.
Heavy metals
We test every batch for harmful levels of lead, arsenic, cadmium, and mercury, and require every product to meet strict safety limits.
We don't just buy ingredients. We build relationships.
Every ingredient partner we work with reflects a shared belief: that people deserve products built on real science, sourced responsibly, and manufactured with integrity. That's how we can stand fully behind every product we bring to market.
