The are formulated to be preservative & steroid free, and can used during pregnancy, breastfeeding and kids from 12 months.
These solutions often have the natural ingredient iota-carragenan sourced from red seaweeds such as Eucheuma cottonii . Some may use the carrageenan Kappaphycus alvarezii . The carrageenan forms a barrier in the nasal passage that traps cold viruses, helping to reduce their multiplication and spread, allowing your body’s natural defences to sweep the viruses away from the nasal lining.

Is Whole Seaweed Effective?
For over 50 years, seaweed has been known to be effective as an antiviral compound and even tested against remdesivir in 2021. But the introduction and widespread sale of commercial products is a welcoming sign.
Marinome say a particular advantage of their carrageenan type product is the broad activity of the polymer against different virus strains, such as rhinovirus and colds and flus. They also show activity against coronaviruses. In clinical trials with more than 600 patients suffering from early symptoms of the common cold they show great improvement. Products containing their extracts, such as nasal sprays, lozenges or a throat spray have been marketed in Austria since 2008 and now have been established as the first causative treatment of common cold and flu-like diseases worldwide and are distributed in more than 40 countries.
Biosea Health suspects that the consumption of seaweed as a daily food will be effective in reducing the impact of viruses. That it reduces disease load in pigs and chickens in meat broiler and egg production is demonstrated. Research is needed to confirm.
