Spirulina for Dogs: Benefits, Dosage and How to Supplement

From ancient Aztec and Mesoamerican civilizations to the National Aeronautics and Space Administration (NASA), spirulina has been prized for its nutritious benefits in humans and animals. Learn how this superfood can help support your dog's health.

What Is Spirulina for Dogs?

Blue Spirulina for dogs is derived from the phycocyanin in the blue-green algae species, Arthrospira platensis. It is known as spirulina because of its spiral or helical nature.

One of the oldest life forms on Earth, blue-green spirulina was used as a food source by Aztecs, who harvested it from Mexico's Lake Texcoco and made it into cakes called tecuitlati.

In the mid 20th century, scientists began exploring its use as a supplement for humans due to its immune-enhancing benefits. Spirulina has earned endorsements from NASA and the European Space Agency (ESA) as a food suitable for long space missions. Today, spirulina is included in EverRoot dog supplements, as well as spirulina supplements for people, pets, and livestock.

Do Dogs Need Spirulina?

Is spirulina good for dogs? Yes, blue-green spirulina is good for dogs that need support for immune and digestive issues because it's packed with macronutrients such as:

  • Protein
  • Healthy fats
  • Vitamins B1, B2 and B3 for energy
  • Vitamins A, C, D, and K
  • Essential minerals potassium and magnesium

What Are the Benefits of Spirulina for Dogs?

Supplementation with blue-green spirulina has the potential to help dogs in a variety of ways by:

  • Enhancing immune system function
  • Improving gastrointestinal health
  • Aiding in detoxification
  • Reducing allergic reactions
  • Preventing and treating cancer
  • Helping moderate inflammation

To demonstrate spirulina's benefits for dogs in immune and intestinal health, Purina conducted a study of dogs fed a diet supplemented with spirulina. The 30 dogs, which were Huskies and Husky mix-breeds, were all fed the same high-protein Purina dog food. Half of the subjects also received a blue-green spirulina dog supplement.

During the 42-week trial, blood and fecal samples were taken every four weeks. The results showed the dogs fed the diet with the spirulina supplement demonstrated enhanced immune status with high antibody response and a significant increase in gut microbiota stability after just nine weeks of supplementation. The benefits continued throughout the trial and even extended beyond the trial period.

Signs Your Dog May Benefit from Spirulina

There are several signs your dog could benefit from the immune- and microflora-supporting benefits of a spirulina dog supplement, such as:

Can spirulina help your dog's allergies? Yes! Allergies are the result of an overactive immune system. Spirulina for dogs may help reduce allergic reactions due to its role in supporting your dog's gut microflora and immune health.

Spirulina grows all over the world, so you want to make sure the spirulina in your dog's supplement is grown in clean, unpolluted waters and is not contaminated with harmful algae or heavy metals.

The NASC certification is your assurance that the spirulina used in EverRoot dog supplements is sustainably sourced from clean, unpolluted waters.
