The Science & Benefits of SEAL

Chitosan's Role:

Chitosan, a linear polysaccharide composed of β--linked D-glucosamine and N-acetyl-D-glucosamine, has been a trusted component in bleeding management since 2003. It adheres to fibrinogen, enhancing platelet adhesion and promoting rapid blood clotting and hemostasis.

SEAL's Unique Formulation:

Offered as an aerosolized version of chitosan, SEAL is available in three sizes:

Small (1.5 oz) OTC • Medium (2.5 oz) Rx •  and Large (7.1 oz) Rx.

Offered as an aerosolized version of chitosan. Packaged in a single-use aluminum aerosol can, it is designed for efficiency and ease of use.
