Sourcing Philosophy

We choose ingredients for their role, form, quality documentation, and fit within a daily wellness routine.

Form Matters

The form of an ingredient matters. Magnesium glycinate, prebiotic fiber, probiotics, and vitamin forms all serve different roles in a formula.

Origin Matters, But Proof Matters More

A strong sourcing story is important, but supplier documentation, identity review, and consistency matter just as much as geography.

Purposeful Selection

Each Yvora ingredient is selected for a clear role in the Day + Night system.

Transparent Sourcing Notes

Ingredient origin notes on our website represent common quality sourcing regions or ingredient origin stories. Final sourcing may vary by supplier and production batch.
