Livia One Probiotic Nasal Spray

Yes. Every product in our line undergoes independent third-party testing for purity, potency, and the absence of harmful contaminants. We believe you should never have to guess what's in your supplement.

We recommend starting with a functional assessment so recommendations are based on your actual biomarkers — not guesswork. Our practitioner team guides every personalized protocol from objective data, not one-size-fits-all advice.

While our formulas use high-quality, well-researched ingredients, we always recommend consulting your healthcare provider before adding any new supplement if you are on prescription medications. Our practitioners are available to help navigate this conversation.

Most clients report meaningful changes within 4 to 8 weeks of consistent use, though this varies based on individual health status and lifestyle factors. Supplements work best as part of a broader, consistent wellness strategy — not as a quick fix.

Our supplements are manufactured in cGMP-certified facilities in the United States, adhering to the highest standards for quality, safety, and ingredient integrity. We partner only with manufacturers who share our commitment to transparency.
