benefits of frozen supplements versus traditional shelf-stable

Feeding your dog frozen, whole ingredient supplements better aligns with many veterinarian nutritionists' emphasis on fresh, minimally processed nutrition, which preserves vital nutrients and bioactive compounds that are often diminished in shelf-stable products. Additionally, scientific research underscores several key reasons why frozen whole-ingredient supplements can be healthier for dogs. Below are some of the most important nutritional benefits behind why we created the first ever whole ingredient frozen dog supplements.

There are so many different trends in the dog food industry—raw diets, freeze-dried, better kibble, fresh frozen, and the list goes on. Let’s face it, it’s hard to know what really *is* the best option for you and your furry best friend. Our take: if you’re working with your veterinarian on improving the health of your dog with nutritious whole ingredients, then you’re probably doing great by them no matter what. But there are some key differences between feeding traditional shelf-stable supplements and frozen supplements that include whole ingredients like Puppops. Either way, if you’re reading this blog, you’re likely feeding your dog better than most!

 

Firstly, frozen supplements made from whole ingredients can offer significant health advantages. Feeding your dog frozen, whole ingredient supplements better aligns with many veterinarian nutritionists' emphasis on fresh, minimally processed nutrition, which preserves vital nutrients and bioactive compounds that are often diminished in shelf-stable products. Additionally, scientific research underscores several key reasons why frozen whole-ingredient supplements can be healthier for dogs. At Puppops, we take dog nutrition seriously. Below are some of the most important nutritional benefits behind why we created the first ever whole ingredient frozen dog supplements.

Enhanced Nutrient Retention

One of the primary benefits of freezing fresh, whole ingredients is the preservation of nutrients. That’s why at Puppops we often say, “Frozen is fresh.” It’s important to know that freezing fresh ingredients locks in nutrient density better than alternative methods of creating a stable product. For example, heat processing plus the long storage times associated with shelf-stable supplements can often degrade sensitive vitamins and antioxidants, reducing their overall efficacy. A study published in The Journal of Animal Science highlights that frozen raw diets maintain higher levels of macronutrients and micronutrients compared to processed, extruded diets, which often lose bioactive compounds during manufacturing (1). Freezing immediately after preparation minimizes nutrient loss, ensuring that dogs receive a diet rich in natural vitamins, minerals, and phytonutrients. That’s why we flash freeze our supplements directly in their trays, and ship frozen directly to your door.

Preservation of Bioactive Phytonutrients and Antioxidants

Not only does frozen food keep nutrient density locked in, but the addition of whole, human-grade ingredients boosts a variety of phytonutrients—such as carotenoids, flavonoids, and polyphenols—that support immune function and reduce inflammation. These compounds are often heat-sensitive and can be significantly diminished during the processing of shelf-stable supplements. A review in Veterinary Science emphasizes that plant-based phytonutrients have immunomodulatory and anti-inflammatory effects, which are better preserved in frozen products (4). By maintaining these compounds, our Puppops could help bolster your dog’s immune response and overall health. Not only that, but antioxidants help reduce oxidative stress and can help eliminate free radicals which contribute to certain cancers.

Reduced Use of Fillers and Additives

Don’t get it twisted—shelf-stable supplements have their use. They’re often a little cheaper to make and as we said at the beginning of this piece, they absolutely support your dog’s nutrition. But be aware that most shelf-stable supplements often include fillers, artificial preservatives, and stabilizers to extend shelf life. While these additives are approved for consumption, they can sometimes provoke allergic reactions or gastrointestinal sensitivities in dogs. In contrast, our frozen whole-ingredient supplements never contain any artificial fillers or added preservatives, relying solely on functional, human-grade ingredients to improve your pup’s health one frozen supplement at a time. This reduces the risk of sensitivities and supports digestive health, which is crucial for nutrient absorption and overall well-being.

Improved Palatability and Digestibility

Research indicates that dogs prefer diets with natural flavors and textures, which are often better preserved in frozen ingredients. A study in Frontiers in Veterinary Science shows that diets with microalgae or other whole ingredients are well accepted by dogs and support good digestibility (6). The natural matrix of whole ingredients facilitates better digestion and nutrient absorption compared to synthetic nutrients or heavily processed products. But beyond that, our frozen supplements just taste better than traditional supplements. If your dog is picky with medicinal flavors, our chef-created recipes will push your perspective on what a supplement can and should be.

Support for Immune and Gut Health

Whole ingredients contain complex nutrient profiles and bioactive compounds that support immune function and gut health. A peer-reviewed study in The Veterinary Journal discusses how microalgae supplementation (like algal oil in our ‘One Fish, Two Fish’ Puppops) in dog diets can enhance gut microbiota diversity and promote beneficial bacteria, supporting gastrointestinal health without compromising digestibility (6). Similarly, fresh, whole ingredients preserve natural enzymes and compounds that aid digestion and immune modulation. And we’ve taken this a step further with our ‘Tum-Tum’ frozen supplement puppops, specifically formulated to support gut biome health and be easily digestible even for dogs with sensitive stomachs.

Safety and Nutritional Adequacy

When formulated correctly, frozen supplements based on whole ingredients can meet or exceed nutritional standards for dogs. Scientific evaluations, such as those published in The Journal of Animal Science, demonstrate that diets incorporating fresh or frozen whole foods can satisfy all essential nutrient requirements, provided they are formulated with veterinary oversight (1,3). This ensures that dogs receive balanced nutrition that supports long-term health.

How do these two approaches stack up?

Traditional Shelf-Stable Supplements

Nutrient Retention
  • High nutrient retention
  • Minimal degradation during freezing
  • Lower nutrient retention
  • Nutrients degrade over processing and storage

Presence of Fillers/Additives
  • None or minimal
  • Primarily whole, functional ingredients
  • Often contain fillers, preservatives, stabilizers

Phytonutrients and Antioxidants
  • Well preserved, supporting immune health
  • Reduced due to heat and processing

Palatability and Digestibility
  • Generally better due to natural flavors and textures of whole ingredients
  • Variable
  • May rely on artificial flavors

Safety and Nutritional Balance
  • Can be formulated to meet standards with veterinary input
  • Variable
  • Some may lack balance or contain additives

The Main Point

Frozen supplements made from whole ingredients harness the benefits of minimal processing, preserving vital nutrients, bioactive compounds, and natural flavors. They support immune health, reduce exposure to unnecessary additives, and are often more palatable and digestible for dogs. Scientific evidence confirms that these benefits can contribute to improved overall health, longevity, and well-being in dogs. As the pet industry increasingly emphasizes natural, minimally processed nutrition, frozen whole-ingredient supplements (like Puppops) represent a promising and scientifically supported approach to canine health.
