Ozonated Glycerin Nasal Spray Protocol
How to mix ozonated glycerin with saline for a nasal pump spray, how much to spray, and how often.
Quick answer: Mix ozonated glycerin to 10% in saline for a nasal pump spray, or start at 5% if you are sensitive. Use 1–2 sprays per nostril, 2–3 times a day.
Home method. Best done as recommended by a licensed provider who knows your health history.
What are the basics of ozonated glycerin nasal spray?
- A nasal spray is ozonated glycerin mixed with saline in a nasal pump bottle. It needs no generator or oxygen tank.
- Strength is 10%. If you are sensitive, start at 5%.
- Use 1 to 2 sprays per nostril, 2 to 3 times a day.
- Use saline only. Never use tap water in your nose.
- The amounts assume glycerin at about 10,000 ppm (parts per million, a strength label on the bottle).

How do you use ozonated glycerin as a nasal spray?
| Strength | How to mix | When to use it |
|---|---|---|
| 10% | 1 teaspoon ozonated glycerin added to 3 tablespoons of saline | Standard strength |
| 5% | 1/2 teaspoon ozonated glycerin added to 3 tablespoons of saline | If you are sensitive |
Spray 1 to 2 times per nostril, 2 to 3 times a day.
What are the best tips when using ozonated glycerin nasal spray?
- Glycerin is slow to blend with water. Swirl the mix in a clean glass cup until it looks even, then fill the bottle.
- Label the bottle with the strength and the date.
- Mix fresh. Keep leftovers in the fridge and use them within 24 hours.
- Store the bottle of undiluted ozonated glycerin away from heat and light. If you will not finish it within a few weeks, keep it in the fridge. Mixed batches keep in the fridge for up to 24 hours.
Is an ozonated glycerin nasal spray safe? Side effects and precautions
- Never use tap water in your nose.
- If the spray stings, drop to the 5% mix.
- Use it diluted in saline as described. Do not spray it undiluted.
- Never breathe ozone gas.
- Do not use ozonated glycerin during pregnancy. Check with your healthcare provider before starting, especially if you have a heart or bleeding condition or take blood thinners.
What to look for in a product: made with pure oxygen (not room air or a concentrator), lab-grade glycerin, a stated and tested concentration, and made fresh. The amounts on this sheet assume glycerin at about 10,000 ppm.

- Sterile saline for the mix.
- A clean glass cup and a measuring spoon.
What the studies used
Study doses are listed as printed in each paper. They are not the amounts on this sheet.
- In a test-tube study, ozonated glycerol with 1,000 ppm or more inactivated 94% of SARS-CoV-2 within 20 seconds, and 99.8% after an hour (Takeda 2021). This was a lab study, not a nasal spray in people.
- An ozonized oil nasal spray (2 puffs, 100 µL in all, per nostril every 4 hours) was used together with oil capsules in an open-label series of 77 people. There was no control group, so it cannot show that the spray worked (Izzotti 2021).
Only 3 human studies of ozonated glycerin exist (one skin trial and two single-patient dental reports), and none was nebulized, swallowed, nasal or a mouthwash, so the studies below are on ozonated oils unless noted. No trial has tested an ozonated glycerin nasal spray.
