Omega-3 has become one of the most valued ingredients in pet food formulations, widely associated with cognitive function, cardiovascular health, joint support, and vision. However, recent industry publications suggest that not all omega-3 sources deliver the same nutritional impact or share the same sustainability profile.
Increasingly, expert analyses are moving beyond the mere presence of omega-3 on a label and focusing instead on where it comes from, how bioavailable it is, and how it is produced.
Not all omega-3 sources deliver the same benefits
According to an article published in PETS International Magazine (May 2023), many pet food formulations rely on vegetable oils rich in ALA as their primary omega-3 source. The challenge highlighted in this publication is that dogs and cats have a limited ability to convert ALA into EPA and DHA, the fatty acids most closely linked to functional health benefits in pets.
As a result, even when omega-3 is included in a formula, it does not always translate into the intended nutritional outcome.
Fish oil: a resource under growing pressure
The same article notes that fish oil has long been the most commonly used direct source of EPA and DHA. At the same time, it points out that fish oil depends on finite marine resources. Nearly 90% of global marine fish stocks are reported to be fully exploited, overexploited, or in decline, raising both environmental and economic concerns for the industry.
This situation has led formulators and manufacturers to reassess not only the sustainability of fish oil, but also its long-term availability and cost stability.
Why alternative sources are gaining attention
In response to these challenges, industry publications increasingly explore alternative omega-3 sources, particularly those derived from microalgae. Microalgae are described as the original source of DHA in the marine food chain, as fish obtain these fatty acids by consuming algae.
A technical document published by GlobalPETS highlights that microalgae-based DHA can help reduce pressure on marine ecosystems, while also offering greater traceability and a more consistent composition for pet food formulations.
Sustainability becomes part of formulation decisions
Beyond omega-3 as a nutrient, the articles reflect a broader shift within the industry: sustainability is moving from a value-added concept to a practical decision-making criterion.
Life cycle assessments of raw materials and the search for ingredients with a lower environmental footprint are increasingly influencing formulation strategies, particularly for functional ingredients such as essential fatty acids.
A conversation that continues to evolve
The publications agree that discussions around omega-3 sourcing in pet food will continue to evolve. Factors such as bioavailability, origin, and sustainability are beginning to carry weight comparable to nutrient concentration alone.
Within this context, solutions developed from microalgae are starting to align with these industry trends. Ingredients such as AlgaPrime, based on microalgae-derived DHA, fit within this broader approach that prioritizes direct sourcing, traceability, and long-term sustainability, as highlighted in recent specialized publications.
