🐾 Why Pet Food Factories Are Increasing Use of Fish Oil in 2025

In 2025, global pet food manufacturers are rapidly increasing their use of fish oil to improve nutrition, enhance palatability, and meet rising consumer expectations. With the growth of premium pet food and the clean-label trend, fish oil has become one of the most important functional ingredients in the industry.

1️⃣🌊Introduction

In recent years, the global pet food industry has shifted toward higher nutrition standards, cleaner ingredients, and premium formulations. Entering 2025, one ingredient stands out as a rising star for manufacturers worldwide: fish oil. Whether for dogs, cats, or aquaculture species, fish oil has become one of the most in-demand functional additives due to its nutritional value, palatability benefits, and cost-effectiveness.

This article explains why pet food factories are increasing their use of fish oil in 2025, which grades are most commonly used, and what buyers should consider when sourcing from Vietnam.

2️⃣🧠Rising Demand for Premium Nutrition

Pets today are treated as family members, pushing brands to produce healthier, more nutrient-dense food. Fish oil supports:

• Brain & vision development 
• Joint health & anti-inflammation 
• Stronger immune system 
• Shiny coat and skin health 
• Better digestion and vitality 

3️⃣🛡️Fish Oil as a Natural Source of Omega-3

Fish oil naturally contains high levels of:

• EPA (Eicosapentaenoic Acid)

• DHA (Docosahexaenoic Acid)

• Omega-3 fatty acids essential for pets

Key benefits for pets:

• Supports brain and vision development

• Reduces inflammation and joint issues

• Strengthens immune system

• Enhances skin and coat health

• Improves digestion and overall vitality

Compared to synthetic additives, fish oil remains clean-label, recognizable, and trusted by manufacturers and pet owners.

4️⃣🧬Palatability: A Key Reason for Increased Use

Pet food factories need ingredients that enhance taste and smell, helping animals consume more consistently.

Fish oil provides:

• A natural aroma that attracts pets

• Higher acceptance rates for both dry and wet food

• Better binding and coating in kibble production

This makes fish oil especially valuable for:

• Premium dog food

• Cat food, which is naturally fish-oriented

• Functional pet food blends

In 2025, as premiumization increases, palatability enhancers like fish oil become essential.

5️⃣✨ Supply Stability from Vietnam 

Vietnam is one of the largest and most stable sources of pangasius-based fish oil. Pet food factories choose Vietnam because of:

• Reliable raw material supply
• Consistent quality
• Competitive pricing
• Availability of Olein—the preferred grade
• Fast export & strong documentation support

6️⃣🐟Types of Fish Oil Commonly Used in Pet Food

Pet food producers typically choose from the following grades:

Why Olein Is Preferred

The olein fraction remains liquid and stable, making it ideal for:

• Spray coating

• Palatability enhancement

• Omega-3 enrichment

• Uniform application on food surfaces

7️⃣💰Cost Efficiency in 2025

As ingredient prices fluctuate worldwide, fish oil remains one of the most cost-efficient ways to add omega-3 nutrition and palatability to pet food. It provides excellent value per dollar compared to alternatives like salmon oil or algae oil.

8️⃣🍃Clean-Label Trend Supports Fish Oil

Consumers increasingly prefer natural, recognizable ingredients. Fish oil fits clean-label requirements perfectly and helps brands market benefits such as:

• “Natural omega-3 source”
• “Supports skin & coat health”
• “Improves digestion and immune response”

9️⃣📝Conclusion

Fish oil usage in pet food manufacturing will continue rising throughout 2025 due to:

• Strong consumer demand for omega-rich nutrition

• Improved palatability and product appeal

• Cost efficiency and consistent supply

• Clean-label marketing benefits

• Flexible grades suited to multiple formulas

Thanks to Vietnam’s reliable production and competitive pricing, fish oil—especially Olein Fish Oil—is set to remain one of the most essential ingredients in the global pet food industry.
