What is NutrientBoost™?

NutrientBoost™ is our line of recipes powered by plasma, a nutrient-rich liquid comprised of vital proteins such as albumin, globulin & fibrinogen. When cellular matter (red blood cells, white blood cells and platelets) is isolated from blood, the remaining fluid is referred to as plasma. While plasma is approximately 92% water, the remaining portion contains proteins that offer a wealth of gut health benefits for dogs and cats.

This natural food ingredient, found in any and all meat, has been consumed by our furry friends for centuries. As a natural ingredient added to pet food, plasma is a superior source of protein providing minerals, antibodies and 18 amino acids to your pet’s diet.

How Does NutrientBoost™ Work?

Plasma is a natural ingredient that actively supports the immune system and overall gut health. When intestinal inflammation occurs due to one of many factors (stress, pathogens, or antinutritional factors), the immune system is activated in response. Activation of the immune system (or intestinal inflammation) utilizes a significant amount of nutrients, which may lead to a deficiency in those same nutrients for normal functioning and performance.

The functional characteristics of plasma proteins, such as albumin and globulin, can modulate the immune system and reduce inflammation that would consequently deplete nutrients. Plasma can also increase the absorption and utilization of nutrients within the body.

Inflamed gut

Intestinal inflammation can block vitamins and nutrients that would otherwise be used for energy and overall health

Healthy gut

The antibodies found in plasma can be helpful for pets experiencing inflammation in the gut

By reducing gastrointestinal distress and retaining important nutrients, NutrientBoost™ can help maintain a balanced gut and support the immune system for the overall health and wellness of your pet.

About Solid Gold

When our founder, Sissy McGill, founded the company over 45 years ago, she believed every pet deserved to be healthy and happy. She also believed the key to a long, happy life was a solid nutritional foundation. In 1974, she set out to create the best food for her dogs and Solid Gold, America’s first holistic pet food, was born.

Up to 80% of the immune system is influenced by the gut.

Our carefully crafted recipes cleanse with whole superfoods, balance with living probiotics, and fuel with omega fatty acids for gut health and overall immune support.
