FLO Travel Nasal Spray 20ml – Carrageenan & Saline Moisturising Nasal Spray for Cold Virus Protection & Nasal Hygiene

FLO Travel Nasal Spray combines isotonic saline with carrageenan — a naturally derived seaweed extract with clinically studied antiviral properties — in a convenient 20ml travel-sized spray. Carrageenan forms a physical barrier in the nasal passages that traps and inactivates cold viruses (rhinovirus, coronavirus) before they can infect nasal cells. Clinical studies show carrageenan nasal spray can significantly reduce the duration and severity of cold symptoms when used early in infection or preventively during high-risk periods (travel, crowded environments).

• Carrageenan — naturally traps and inactivates cold viruses in the nasal passage
• Isotonic saline — moisturises and cleanses nasal tissues
• Clinically studied for cold virus protection
• 20ml travel size — carry-on friendly
• Drug-free — suitable for daily and preventive use

Frequently Asked Questions

How does carrageenan protect against cold viruses?

Carrageenan is a sulphated polysaccharide extracted from red seaweed. In the nasal passages, it forms a viscous gel that physically coats the nasal mucosa — creating a barrier that binds to and traps cold viruses (including rhinovirus and various coronaviruses) before they can attach to and infect nasal epithelial cells. This mechanical antiviral action is independent of the immune system — it is a physical barrier rather than a pharmacological effect, which is why it has no drug interactions and is safe for all ages.

Is FLO Travel Nasal Spray effective against the flu?

Carrageenan has demonstrated activity against influenza virus in laboratory studies. Clinical trials have primarily focused on rhinovirus (common cold) and some data on coronaviruses. It is most relevant for cold virus protection. For influenza protection, annual flu vaccination remains the primary recommendation.

When should I use FLO Travel Nasal Spray?

Use before and during high-risk cold exposure — before boarding a plane, during air travel, in crowded venues, at conferences, when caring for a sick family member, or when you first notice early cold symptoms. In clinical trials, early use at the first sign of a cold reduced duration by approximately 1.9 days compared to placebo.

Can children use FLO Travel Nasal Spray?

FLO Travel Spray is drug-free and suitable for children — check the product label for minimum age recommendations. The saline and carrageenan formula is gentle enough for paediatric nasal use. A smaller paediatric spray is available from FLO for younger children.

Is this spray safe to use daily throughout cold season?

Yes. Carrageenan and saline are both safe for daily preventive use with no dependency or tolerance concerns. It can be used 2–4 times daily as a preventive nasal spray during cold and flu season or whenever cold exposure risk is elevated.
