Our Nasal Iodine Cleanse uses potassium iodine, which is specifically formulated for nasal use and is gentler on delicate nasal membranes. Potassium iodine at 1% concentration effectively kills 99% of germs within 90 seconds without the harsh irritation associated with povidone iodine. Our formula is enhanced with fulvic acid to provide additional protection and hydration, making it safe for daily use without burning or stinging.
Each 2 fl. oz. bottle of Nasal Iodine Cleanse produces approximately 200-240 sprays depending on usage. With recommended use of 1-2 sprays per nostril once daily, one bottle typically lasts 1-2 months for a single user. We recommend getting one bottle for each family member to avoid sharing.
Yes, our Nasal Iodine Cleanse is a clear, mineral-based liquid that is exceptionally gentle on nasal mucosa. The formula combines potassium iodine with fulvic acid to create a non-irritating solution that hydrates and protects the mucosal lining. Unlike steroid nasal sprays, there's no burn, no sting, and no throat drip. Users report it feels comfortable and soothing, even with daily use.
Our Nasal Iodine Cleanse contains a 1% concentration of potassium iodine, which is the optimal strength for nasal use. This concentration is clinically proven to kill 99% of germs within 90 seconds while remaining gentle enough for daily use without irritation or side effects. It's the same concentration trusted by healthcare professionals for infection prevention.
Yes, Nasal Iodine Cleanse is third-party tested for purity, potency, and safety. Every batch undergoes rigorous quality control testing to ensure it meets pharmaceutical-grade standards. Our formula is manufactured in FDA-registered facilities in the USA and is non-GMO with no artificial additives or harmful chemicals.
Our Nasal Iodine Cleanse is a topical nasal cleanser and does not interfere with most medications. However, if you have a medical condition, are taking prescription medications, or have concerns about thyroid conditions, we recommend consulting with your healthcare provider before use. If you're currently using other nasal sprays or medications, you can typically use Nasal Iodine Cleanse at different times of the day (for example, use prescription medications in the morning and Nasal Iodine Cleanse at night for cleansing).

"I'm a pharmacist and was tired of steroid sprays with side effects. Nasology changed everything for my post-nasal drip and keeping me healthy. I use it twice daily and haven't been sick all winter. No burn, no sting!"
"I work in the ER surrounded by sick patients. My coworkers got the flu but I stayed healthy using Nasology before and after shifts. Same iodine hospitals trust. My whole family uses it now!"
"I was skeptical until I got the flu while my wife stayed healthy. Now I use it after the gym and crowded places. So easy - just spray and go. No weird taste or irritation!"
"Mom of three here. Since using Nasology after school each day, way fewer sick days! Gentle for my 6-year-old and pediatrician-recommended. Better than constant cold medicine!"
"My ER doctor uncle recommended this. I travel constantly and used to get sick from planes. Now I spray before flights and haven't been sick in 4 months. Game changer!"
