Ascophyllum nodosum

Can Ascophyllum nodosum be safely given to pregnant, nursing and young animals?

The safety and efficacy of Ascophyllum nodosum has yet to be determined for pregnant, nursing and young animals. We do not recommend feeding Ascophyllum nodosum to dogs and cats under 6 months of age.

Does the Ascophyllum nodosum need to come into direct contact with my pet’s teeth to be effective?

No. Ascophyllum nodosum works systemically through the bloodstream and thus does not need to come into contact with the teeth.

How long until results become noticeable?

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

Is Ascophyllum nodosum harmful to my garden or the environment?

No. Residual product excreted by animals is not harmful to gardens, nor is the seaweed damaging to the environment if introduced into waterways.

Is Ascophyllum nodosum suitable for pets with sensitive stomachs?

Whilst Ascophyllum nodosum is usually well tolerated, each animal is different. Ensure that your pet’s gastrointestinal system is at its best before introducing Simply Seaweed. Introduce the product slowly, gradually increasing the dose as toleration is evident.

Probiotics may help with transition – products such as SkinnyDog Kefir, Protexin or lactose free yogurt.

Why must I consult my veterinarian before using this product if my pet has thyroid problems?

Seaweed is naturally high in iodine, a mineral which affects the thyroid. Seek veterinary advice beforehand if you would like to give your animal Ascophyllum nodosum.

Will my pet like the taste? If they don’t, do you have any suggestions?

In our experience, dogs are not usually bothered by the product being added to their food. Cats, however, can sometimes be a bit fussy.

Some suggestions are;

  • Start by introducing a very small quantity of the product, gradually increasing the amount up to the recommended dosage
  • If feeding kibble, add a splash of water into the bowl then swirl around the biscuits so that the Ascophyllum nodosum sticks to the biscuits
  • Mix the Ascophyllum nodosum in with a small amount of something yummy, such as lactose free yoghurt, chicken stock, gravy, margarine, sardines, a splash of milk, Brewer’s Yeast or peanut butter
  • For dogs, try hide the Ascophyllum nodosum inside a piece of “dog log” e.g. Prime100


Can my pet eat seaweed if they are allergic to seafood?

As seaweed is the natural habitat of many fish and shellfish, there may be traces of marine life in any seaweed product. If your pet has a serious fish or shellfish allergy, they should not be allowed to consume any seaweed products including Simply Seaweed. Pets that are intolerant of seaweed or algae derivatives should also refrain from consuming seaweed products including Simply Seaweed.

It is important to understand the difference between a food intolerance and a food allergy. Whilst they can share many clinical signs, food intolerances are usually less severe and limited to digestive issues. An intolerance is a chemical reaction that occurs within the body, whereas an allergy is an immune system response. A serious allergy can affect the nervous system and result in a life threatening situation.

What is the difference between seaweed, kelp and algae?

Seaweed is a plant that grows in the sea.

Kelp is a type of seaweed that is big and brown.

Algae refers to aquatic organisms that have the ability to conduct photosynthesis. Seaweed is included in this group.

Simply Seaweed

Can I purchase products direct from Simply Seaweed?

No. Simply Seaweed is a wholesaler only. Please see our list of Stockists to find a retailer.

Does Simply Seaweed come with a measuring scoop?

No. We do not include a plastic measuring scoop in every container of Simply Seaweed for the benefit of our environment. Instead, we recommend using standard kitchen measuring spoons.

Does Simply Seaweed contain any additives or preservatives?

No. The product is 100% pure certified organic Ascophyllum nodosum.

Does Simply Seaweed contain any heavy metals?


All wild-harvested seaweed and kelp products contain some level of heavy metals, due to ocean contamination and naturally occurring minerals.

We only harvest from clean waters to ensure minimal levels, and our end product is heavy metal tested to ensure that any detected quantities are within safe limits as per the Food Standards Australia New Zealand (FSANZ 2002). Additionally, our seaweed is certified organic which enforces even more stringent regulations of allowable trace levels of heavy metals.

Our Nutrition Data discloses the levels of heavy metals.

Is Simply Seaweed heat treated?

No. Unlike most other products available on the market, Simply Seaweed’s Ascophyllum nodosum has not undergone heat treatment or been dried using excessive heat. This means that 100% of the antioxidants, enzymes, vitamins and antibacterial benefits are retained.

Is Simply Seaweed irradiated?

No. Simply Seaweed products are not irradiated, ensuring their safety for cats.

Where is Simply Seaweed made?

Ascophyllum nodosum does not occur naturally in Australian waters and is therefore imported from other countries, usually Canada, Ireland, England, Scotland or Norway. Please check individual containers to see where the batch was harvested. The seaweed is sent directly from the country of origin to Australia, where it is then locally packaged and prepared for distribution.

Why does Simply Seaweed vary in colour, granule size, texture etc.?

There are many factors that contribute to variations in our product. These include:

  • The age of the seaweed plant when it was harvested
  • How long ago the plant was harvested
  • If the seaweed was growing close to the water’s surface, or deep below
  • How long the seaweed was left out to dry before being processed
  • The method of drying
  • The method of crushing
  • Storage conditions
  • Position in storage container
