Amino acid bioavailability is key to how well dogs absorb and use nutrients, impacting muscle health, skin, coat, and energy levels.
Study shows that not all proteins in commercial dog foods are highly bioavailable, affecting nutrient absorption and overall health.
THRIVE Daily enhances amino acid bioavailability, ensuring dogs receive essential nutrients for optimal health and vitality.

What Is Amino Acid Bioavailability?
When it comes to feeding your dog, it's not just about how much protein is in their food. The quality of that protein matters just as much. This is where amino acid bioavailability comes in. Amino acid bioavailability refers to the percentage of amino acids that are absorbed into the bloodstream after being digested. It’s not enough for your dog to eat protein—their body needs to absorb and use those nutrients effectively.
Why Amino Acid Bioavailability Matters
Many pet owners focus on the protein content listed on dog food packages. However, not all proteins are created equal. The bioavailability of the protein source affects how well it will be absorbed and utilized by your dog’s body. Proteins with low amino acid bioavailability may not provide all the nutrients your dog needs, even if they consume the right amount of food.
Key Benefits of High Amino Acid Bioavailability in Dogs
Ensuring your dog has access to highly bioavailable amino acids can lead to numerous health benefits, including:
- Muscle maintenance and growth
- Enhanced immune system support
- Healthier skin and coat
- Increased energy levels and vitality
The Science Behind Amino Acid Bioavailability
In a recent study by Hendriks et al. on canine nutrition, researchers focused on how dietary protein and amino acids are absorbed at the ileal level —the final section of the small intestine. The study found that measuring amino acid bioavailability at the ileum is more accurate than fecal measurements, as much of the digestion and absorption happens earlier in the gastrointestinal tract.
The study revealed that certain amino acids, such as lysine and cysteine , can be less bioavailable due to the way they are processed in commercial dog foods. This reduced bioavailability means that even if the dog food contains these amino acids, your dog may not be getting the full benefit of them due to how they’re absorbed.

Findings from the Study
The study reviewed data from 158 different canine diets and concluded that:
- Proteins need to be broken down and absorbed before reaching the large intestine.
- Commercially processed dog foods often have lower bioavailability of key amino acids.
- Higher protein content does not always translate to higher amino acid bioavailability.
How Amino Acid Bioavailability Affects Your Dog’s Health
The study’s findings highlight how crucial amino acid bioavailability is to canine nutrition. If the proteins in your dog’s food are not bioavailable, they won’t provide the necessary building blocks for maintaining muscle, repairing tissue, or supporting the immune system. This can lead to long-term health issues, even if you think you’re feeding your dog a high-protein diet.
Common Signs of Low Amino Acid Bioavailability in Dogs
- Dull coat and skin problems
- Muscle loss or weakness
- Reduced energy levels
- Slower recovery from injury or illness

How THRIVE Daily Enhances Amino Acid Bioavailability
One way to ensure your dog is getting the most out of their nutrition is by incorporating supplements that focus on amino acid bioavailability, like THRIVE Daily. THRIVE Daily is specifically formulated to provide essential amino acids in a highly bioavailable form, making it easier for your dog’s body to absorb and use these nutrients effectively.
Why Choose THRIVE Daily for Amino Acid Bioavailability?

- It contains amino acids in forms that are more easily absorbed compared to processed dog foods.
THRIVE Daily is ideal for pet owners who want to improve their dog’s overall health by focusing on the quality, not just the quantity, of the nutrients their dog consumes.
Maximizing Your Dog’s Health with Amino Acid Bioavailability
As the study shows, understanding amino acid bioavailability is key to providing the best nutrition for your dog. Here are some tips to ensure your dog is getting the right nutrients:
- Choose high-quality protein sources with proven bioavailability.
- Incorporate supplements like THRIVE Daily to enhance absorption.
- Ensure that your dog’s diet includes essential amino acids like lysine, methionine, and cysteine.
By focusing on bioavailability, you can help your dog live a healthier, more active life. Amino acid bioavailability isn't just a buzzword—it's a critical aspect of nutrition that can make a significant difference in your dog's overall health.
Insights from Stuart
"Whether it be raw food or Kibble, the amino acids in there are all bound. They're not what we call free form. So the digestive system has to break all the protein down and try to extract all the amino acids. And in that process, you can't guarantee that you get 100 % absorption of the amino acids from the protein."

With a focus on scientifically backed nutrition, you can give your dog the best chance to thrive. After all, it’s not just about what your dog eats—it’s about how well they can use what they eat.

Frequently Asked Questions
What is amino acid bioavailability and why is it important for my dog?
Amino acid bioavailability refers to the percentage of amino acids that are absorbed and utilized by your dog’s body. It's crucial because even if your dog consumes enough protein, they won’t benefit unless those amino acids are bioavailable. High bioavailability ensures optimal muscle health, energy levels, and overall well-being.
How does amino acid bioavailability affect my dog’s health?
Low bioavailability means your dog may not absorb essential nutrients properly, leading to issues like muscle loss, dull coat, low energy, and poor recovery from injuries. Ensuring that your dog’s diet includes highly bioavailable amino acids supports better digestion, skin health, and vitality.
How do I know if the proteins in my dog’s food have high bioavailability?
Check the ingredients and research the protein sources. High-quality proteins from animal sources tend to have better bioavailability than plant-based proteins. Additionally, look for supplements or dog foods that mention amino acid bioavailability in their formulation.
How does THRIVE Daily relate to amino acid bioavailability?
THRIVE Daily is formulated with high-quality, bioavailable proteins that are easily absorbed by your dog’s body. This ensures that your dog is receiving the essential amino acids they need for muscle maintenance, immune support, and overall health.
Can I improve my dog’s amino acid bioavailability with supplements?
Yes, supplements like THRIVE Daily are designed to enhance amino acid bioavailability. They provide your dog with easily digestible amino acids, ensuring that the nutrients are effectively absorbed and used by their body for improved health and performance.
