What Is NoWonder Nasal Spray? Everything You Need to Know

NoWonder™ is a nitric oxide nasal spray developed by SaNOtize Research and Development Corp., a Canadian biotech company. In the United States it is sold as a cosmetic nasal cleanser — and it is the same product sold internationally under the name Enovid. If you've heard of Enovid, you already know NoWonder™. If this is your first time, this guide covers everything: what it is, how it works, who uses it, and where to get it.

(Enovid is now called NoWonder — read the full background on the name change.)

What Is NoWonder™ Nasal Spray?

NoWonder™ is a nitric oxide nasal spray (NONS) — a patented formulation that generates nitric oxide gas within the nasal passages when the solution is sprayed. It is designed for daily nasal hygiene: cleansing and moisturising the nasal cavity while supporting the nasal passages' natural environment.

The product is manufactured in Canada by SaNOtize, a company founded by scientists who pioneered nitric oxide delivery technology. It is available in a 25ml TSA-compliant spray bottle and is sold by BuyEnov.com, an authorized global retailer since 2021.

NoWonder™ is available in pack sizes ranging from 2-pack to 12-pack. You can shop all pack sizes at BuyEnov.com.

The Science: Nitric Oxide and Your Nasal Passages

What Is Nitric Oxide?

Nitric oxide (NO) is a molecule naturally produced by the human body. Its importance in human physiology was recognized when three scientists — Robert Furchgott, Louis Ignarro, and Ferid Murad — were awarded the Nobel Prize in Physiology or Medicine in 1998 for their discovery of its role as a signalling molecule in the cardiovascular system.

Beyond cardiovascular health, nitric oxide plays a known role in the body's first-line nasal defence. The nasal passages naturally produce small amounts of NO, and research has explored how exogenous (externally applied) nitric oxide interacts with the nasal environment.

NONS Technology — How It Works

SaNOtize's patented NONS (Nitric Oxide Nasal Spray) platform is designed to deliver nitric oxide directly into the nasal cavity. When the solution — containing sodium nitrite and citric acid — is sprayed, a chemical reaction generates nitric oxide gas within the nasal passages.

This is distinct from saline sprays, steroid sprays, or decongestants. NoWonder™ is steroid-free, contains no vasoconstrictors, and does not cause rebound congestion. It works through the nitric oxide chemistry rather than any pharmaceutical mechanism.

What's In It: Ingredients

NoWonder™ has a straightforward ingredient list. Full details are available on our ingredients page.

• Purified water — base carrier
• Sodium chloride — isotonic salt, consistent with standard nasal saline
• Citric acid — reacts with sodium nitrite to generate nitric oxide
• HPMC (hydroxypropyl methylcellulose) — gel-forming agent that helps the solution adhere to nasal mucosa
• Sodium nitrite — the nitric oxide precursor
• Benzalkonium chloride — preservative, standard in nasal sprays

The formula is free from steroids, antihistamines, and decongestants. It does not cause drowsiness and has no known drug interactions reported in studies.

How to Use NoWonder™

4. Repeat in the other nostril

Who Uses NoWonder™?

Over 70,000 customers worldwide have used NoWonder™ / Enovid since BuyEnov.com began distributing in 2021. The product is used across a wide range of lifestyles and contexts:

Frequent Travelers

Aircraft cabins, airports, and hotels expose passengers to high foot-traffic environments. Many frequent flyers incorporate NoWonder™ into their travel nasal hygiene routine — applying sprays before boarding, during long-haul flights, and upon arrival.

Healthcare Workers

Nurses, doctors, and allied health professionals working in clinical environments use NoWonder™ as part of their daily nasal hygiene practice. Several customers in this group appear in our verified review database.

Immunocompromised Individuals

Customers managing cancer treatment, autoimmune conditions, and other vulnerabilities have written extensively about the confidence NoWonder™ gives them in daily life. Their testimonials consistently reference it as a tool for maintaining everyday nasal hygiene alongside other protective measures.

Families and Office Workers

Parents who want to support their family's nasal hygiene — particularly in school-age children (suitable for adults and children 12 and over) — as well as office workers in open-plan environments, make up a significant portion of our customer base.

Clinical Background

Enovid — the international name for the same nitric oxide nasal spray — has been the subject of Phase 2 and Phase 3 clinical trials. These trials are documented and peer-reviewed. We make no clinical claims for the US cosmetic product; however, the underlying nitric oxide nasal spray technology and formulation is the same as that studied in those trials.

You can review the supporting clinical literature on our clinical data page.

• Steroid-free: No corticosteroids of any kind
• No rebound congestion: Unlike decongestant sprays, NoWonder™ does not cause nasal passage rebound
• Non-drowsy: No antihistamines or sedating compounds
