Simply Seaweed - Ascophyllum Nodosum

What is Simply Seaweed?

Simply Seaweed is a dental supplement - 100% dried and crushed Ascophyllum nodosum (a particular species of seaweed).

What does it do?

Ascophyllum nodosum has been proven to improve dental hygiene as well as being used as a nutritional supplement. It may help with:

  • Dental maintenance
  • Prevention of dental disease
  • Prevention, reduction and removal of plaque
  • Prevention of calculus (tartar)
  • Reduction or elimination of halitosis (bad breath)
  • Stain removal and whitening of teeth

How it is used?

Just add to their food – no brushing required!

How does it work?

After being consumed by your pet, Ascophyllum nodosum works in several ways to improve dental hygiene, due to its natural antibacterial, anti-inflammatory and anti-adhesive properties. Existing plaque is softened and new plaque is prevented from sticking to teeth. 

The mechanism of action is still not fully understood, but it is thought that the saliva is affected by the seaweed’s phenols, iodine, phosphates, fucoidans, sulphur, zinc, silicates and sulphates.

For a more detailed answer, please see the journal articles and clinical studies here

Results do vary and may take up to two months to become noticeable. An improvement in breath is usually observed within a few weeks.

Why doesn’t Simply Seaweed use Australian seaweed? Where is it sourced from?

As Ascophyllum nodosum does not occur in Australian waters, it must be imported. Simply Seaweed currently has harvesting partners in Canada and Ireland. Please check the batch code of individual containers to determine the country of origin – “C” indicates Canada, “I” indicates Ireland.
