Iodine Nasal Spray for Cold & Virus Defence

Our Nasal Iodine Spray contains pharmaceutical-grade povidone-iodine (PVP-I) at a concentration specifically formulated for safe, effective nasal use. Each bottle delivers approximately 100 metered sprays in a non-leaching glass bottle — free from alcohol, fragrances, preservatives, and microplastics and Made with USP-certified ingredients.

Shake gently before use. With your head upright, spray two pumps into each nostril. Tilt your head slightly forward and look left for 15 seconds, then right for 15 seconds to allow full coverage across the nasal passages. Use up to twice daily for routine protection, or as needed after exposure to crowded environments such as flights, public transport, offices, or schools. For best results when you feel something coming on, begin use at the very first sign of symptoms — the earlier you start, the more effective it is.

Every respiratory infection — colds, flu, and other viruses — enters your body through the same place: your nose. Viruses land on the nasal mucosa, attach to your cells, and multiply for hours to days before symptoms ever appear. Povidone-iodine is a broad-spectrum antiseptic that neutralises viruses, bacteria, and fungi on contact in as little as 90 seconds. By spraying it directly onto the nasal lining, you're creating an antimicrobial barrier at the exact point of entry — stopping pathogens at the gate before they can establish an infection. This is the same reason surgeons swab patients' noses with iodine before every operation.

Yes. Povidone-iodine has been used safely in healthcare settings for over 60 years. Peer-reviewed research published in the Ear, Nose & Throat Journal confirms that PVP-I at low concentrations can be safely used in the nasal cavity for up to five months of continuous daily use without damaging nasal tissue or affecting ciliary function. The most commonly reported side effect is a mild, temporary taste or slight tingling that resolves within minutes. Our formula uses a concentration specifically chosen to maximise germ-killing potency while remaining gentle enough for everyday use.

Saline spray rinses and moisturises your nasal passages — which can help with dryness and clear some debris — but it has absolutely zero antimicrobial activity. It does not kill a single virus or bacterium. Iodine nasal spray actively destroys pathogens on contact. Think of it this way: saline is like rinsing a cut with water, while iodine is like cleaning it with antiseptic. If your goal is to actually prevent illness rather than just moisturise your nose, you need something that kills the germs — not just washes over them.

Yes. Povidone-iodine nasal preparations have been studied extensively in clinical settings around the world. A 2025 Phase III double-blind, randomised clinical trial published in Frontiers in Medicine found that a PVP-I nasal spray produced clinically meaningful reductions in cold severity — with benefits of up to 39.7% when used within 24 hours of symptom onset. Additional studies at institutions including Stanford, NYU Langone, and the University of Kentucky have examined PVP-I nasal spray for pathogen reduction and healthcare worker prophylaxis. In lab studies, PVP-I has been shown to reduce viral infectivity by up to 99.99% in under 60 seconds.
