Seaweed and Pet Dental Health: What the Science Says

FACTS ABOUT ASCOPHYLLUM NODOSUM

Dental disease is one of the most common health issues in dogs and cats, affecting the majority of pets by the age of three. Left unmanaged, plaque and tartar accumulation can lead to gingivitis, periodontal disease, tooth loss, and even systemic health problems. While daily tooth brushing remains the gold standard, research shows that certain natural supplements - particularly the brown seaweed Ascophyllum Nodosum - can play a valuable role in supporting oral health.

Why Ascophyllum Nodosum?

Ascophyllum Nodosum, a species of brown algae harvested from cold North Atlantic waters, has gained attention in veterinary dentistry due to its unique bioactive compounds. Studies suggest that when ingested, these compounds are absorbed into the bloodstream and excreted into the saliva, where they may alter the bacterial environment in the mouth.

This mechanism can:

• Inhibit plaque-forming bacteria
• Reduce tartar accumulation
• Freshen breath by lowering volatile sulfur compounds

What the Research Shows

Several peer-reviewed studies support the use of Ascophyllum Nodosum in companion animals:

• A 2012 clinical trial published in the International Journal of Applied Research in Veterinary Medicine found that dogs receiving Ascophyllum Nodosum supplementation had significant reductions in plaque, calculus, and oral malodour compared to a placebo group.
• Another randomised, double-blind study (Gawor et al., 2018) reported improved gingival health and reduced tartar in dogs supplemented with Ascophyllum Nodosum.
• The findings are consistent with earlier in-vitro research showing the algae’s antimicrobial properties and ability to influence oral biofilm formation.

These results highlight seaweed’s potential as a preventive tool in managing dental disease.

Beyond Dental Benefits

Seaweed also provides a rich source of iodine, minerals, and trace elements, which contribute to overall health. Additionally, its natural prebiotic content may support gut health, further promoting systemic wellbeing.

Safety Considerations

While generally safe, seaweed supplements are not recommended for pets with thyroid disorders due to their iodine content and also not recommended for pregnant or lactating pets. Always follow dosage guidelines and consult with your veterinarian before introducing any new supplement.

An Evidence-Based, Affordable Choice

Supplements containing Ascophyllum Nodosum are widely used and recommended by veterinarians. However, these products can be costly. Our natural Plaque Control Seaweed contains the same clinically studied seaweed species, offered in bulk at a more affordable price point, making daily dental care accessible for more pet parents.
