The pet food industry is rapidly evolving toward healthier, more sustainable and functional solutions. In this context, microalgae have emerged as one of the most promising ingredients for premium dog and cat nutrition.

At Neoalgae, we have spent more than a decade researching, cultivating and developing biotechnology solutions based on microalgae for different industrial sectors. Through this experience, we have identified the species with the highest potential for functional pet nutrition, not only because of their bioactive compounds, but also due to their technological, regulatory and industrial viability.

Microalgae: A Natural Source of Bioactive Compounds

Microalgae are a sustainable and highly concentrated source of proteins, polysaccharides, pigments, carotenoids, vitamins, minerals and essential fatty acids.

Thanks to this exceptional diversity of bioactive compounds, they can simultaneously support several physiological mechanisms involved in:

  • Gut health
  • Immune system function
  • Metabolism
  • Oxidative stress reduction
  • Cognitive health
  • Overall pet wellness

After evaluating numerous species, Neoalgae selected four key microalgae: Spirulina (Limnospira platensis), Chlorella vulgaris, Haematococcus pluvialis and Schizochytrium sp. Their nutritional and functional profiles are highly complementary and ideal for developing innovative pet nutrition solutions throughout all life stages.

In addition, combining these microalgae with other active ingredients such as postbiotics and bioactive plant matrices may help reduce oxidative stress and support long-term health.

Functional Solutions for Animal Nutrition

At Neoalgae, we develop innovative microalgae-based ingredients for animal nutrition and pet food applications, combining sustainability, functionality and scientific validation. Our expertise includes both whole microalgae biomass and highly valuable bioactive compounds designed to support animal health and wellbeing.

Hybrid Pet Foods: A Growing Market Trend

One of the fastest-growing trends in the pet food industry is hybrid nutrition, combining animal and plant proteins to improve nutritional quality without compromising palatability.

The incorporation of plant-based matrices and microalgae enables the development of healthier, more functional and sustainable products while maintaining excellent taste acceptance among pets.

At Neoalgae, we adapt ingredient ratios and concentrations according to each client’s technical and commercial requirements while maintaining the highest quality standards.

Spirulina (Limnospira platensis)

Spirulina is one of the most extensively studied microalgae in animal nutrition. Its biomass contains approximately 60–70% high-biological-value protein, together with phycocyanin, sulfated polysaccharides, B vitamins and essential minerals such as iron and magnesium.

Scientific evidence suggests that Spirulina supplementation may:

  • Modulate immune response
  • Increase antioxidant capacity
  • Support digestive health
  • Maintain gut microbiota balance
  • Improve nutritional status
  • Help reduce inflammation associated with physiological stress

Chlorella vulgaris

Chlorella is particularly rich in fiber, polysaccharides, chlorophyll, lutein, nucleotides and bioactive peptides.

Studies have shown that it may:

  • Promote gut microbiota balance
  • Improve nutrient digestibility
  • Increase beneficial intestinal metabolites
  • Protect against oxidative stress
  • Support proper immune function

Haematococcus pluvialis

Haematococcus pluvialis is recognized as the richest natural source of astaxanthin, one of the most powerful antioxidants found in nature.

In addition to astaxanthin, it provides lutein, beta-carotene and essential fatty acids.

Scientific evidence indicates that it may:

  • Protect cells against oxidative damage
  • Support immune function
  • Promote skin and coat health
  • Help preserve cellular functionality during aging

Schizochytrium sp.

Schizochytrium sp. is a sustainable, non-marine source of long-chain omega-3 fatty acids, especially DHA (docosahexaenoic acid).

DHA plays a key role in:

  • Nervous system development and maintenance
  • Cognitive function
  • Eye and vision health
  • Skin and coat quality
  • Puppy and senior pet development
  • Inflammatory response modulation

Much More Than Four Microalgae

These four species represent Neoalgae’s most comprehensive proposal for functional pet health ingredients. However, our expertise extends far beyond them.

For more than a decade, we have worked with a broad range of biotechnologically relevant microalgae species, including:

  • Phaeodactylum tricornutum
  • Tetraselmis chuii
  • Nannochloropsis spp.
  • Dunaliella salina
  • Porphyridium cruentum

We also develop solutions based on high-value bioactive compounds derived from microalgae, including:

  • Phycocyanin
  • Fucoxanthin
  • Astaxanthin
  • DHA and EPA
  • Polysaccharides
  • Proteins
  • Natural pigments
  • Other functional bioactive ingredients

If your company is interested in incorporating a specific microalgae species, developing a customized functional ingredient or formulating a new product using microalgae-derived bioactive compounds, our team can help bring your project to life.

At Neoalgae, we do more than supply microalgae: we develop customized biotechnology solutions to drive the next generation of functional pet nutrition.
