Kelp (Ascophyllum nodosum) is a brown seaweed harvested from the clean, cold waters of the Atlantic. It is considered one of nature’s most versatile supplements for dogs. Its wide range of vitamins, minerals, amino acids, and bioactive compounds makes it an excellent, multi-purpose, and nourishing addition to a dog’s diet.
What makes Kelp (Ascophyllum nodosum) special?
This seaweed naturally contains dozens of trace elements and minerals (such as iodine, calcium, potassium, and magnesium), as well as antioxidant compounds, phytonutrients, and polysaccharides. These specific compounds are what make the seaweed unique compared with many other seaweeds.
Key benefits for dogs
• Supports natural oral cleansing – the seaweed’s bioactive compounds are carried via the bloodstream into saliva, where they support the saliva’s normal cleansing functions.
• Coat and skin wellbeing – the seaweed’s natural minerals and amino acids support normal skin function as well as the coat’s strength and shine.
• A natural source of nutrients – up to 70 different trace elements and naturally occurring vitamins.
• General immune support – the seaweed’s antioxidants take part in the body’s normal defense mechanisms.
Kelp (Ascophyllum nodosum) vs. other seaweeds
Why choose Kelp (Ascophyllum nodosum) specifically?
It is, based on research and use, one of the most commonly used seaweeds for supporting dogs’ oral wellbeing. Its moderate iodine content makes it more suitable for long-term use than many other brown seaweeds. It has a balanced mineral profile and is not as one-sided as spirulina or chlorella, which are more protein-rich microalgae than true mineral supplements.
Who is Kelp (Ascophyllum nodosum) nodosum suitable for?
- Dogs whose owners want to support natural oral cleansing.
- Dogs that need a natural mineral supplement.
- Dogs whose coat or skin would benefit from natural nutritional support.
- Dogs eating either a raw diet or dry kibble.
Summary
Kelp (Ascophyllum nodosum) is an effective, safe, and completely natural addition to a dog’s daily feeding. It combines seaweed’s broad nutritional profile with unique bioactive properties in a way that only occurs to a limited extent in other seaweeds. With a small daily serving, a dog receives a large amount of important natural nutrients.

Studies:
-
Effects of Edible Treats Containing Ascophyllum nodosum on the Oral Health of Dogs: A Double Blind, Randomized, Placebo Controlled Single Center Study (Gawor et al., 2018) — In this double-blind randomized study, dogs given a chew/treat containing A. nodosum seaweed showed a significant reduction in plaque and tartar accumulation compared with the placebo group over 90 days. In addition, oral health status (plaque and tartar levels, indicators related to bad breath) was assessed, and improvements were observed.
-
Ascophyllum nodosum as a nutrient supporting oral health in dogs and cats: a review (Gawor & Jank, 2023) — A review article that compiles results from clinical studies and concludes that dietary A. nodosum supplementation is one of the most promising methods of passive at-home oral hygiene for dogs and cats. The article notes that the seaweed reduces plaque and tartar build-up, and it evaluates the effectiveness of different forms (powder, chews, dry food).
- Influence of Dietary Supplementation With a Powder Containing A.N. ProDen (Ascophyllum nodosum) Algae on Dog Saliva Metabolome (Gawor et al., 2021) — A study evaluating the effect of seaweed powder on the dog saliva metabolome. This suggests that A. nodosum may alter saliva composition in ways that could reduce bacterial growth in the mouth, plaque formation, or odor — which supports the rationale for using seaweed for oral hygiene.
