When it comes to your pet's health, what's inside the bottle matters just as much as what's left out. At Bill & Coo, we believe pet wellness starts with transparency. Every ingredient in our formulations is intentionally selected based on its nutritional purpose, never added simply to fill space. We formulate with clean, functional ingredients that support your pet's everyday health, because they deserve products you can trust. Let's take a closer look at what's inside Defend Your Pet and why each ingredient has earned its place.
Carrot Powder: Nature's Source of Beta-Carotene
Carrots are well known for being rich in beta-carotene, a precursor to vitamin A, along with naturally occurring antioxidants. These nutrients help support normal immune function and contribute to overall wellness. In Defend Your Pet, carrot powder provides a wholesome, plant-based nutritional foundation that complements the rest of the formula.
Vitamin C: Everyday Antioxidant Support
Vitamin C is one of the most recognized antioxidants in nutrition. It helps protect cells from oxidative stress while supporting normal immune function. Although dogs naturally produce vitamin C, additional dietary support may be beneficial during periods of physical stress, aging, or increased activity. Cats also benefit from balanced antioxidant nutrition through carefully formulated diets. Vitamin C is included to help support healthy immune function and overall vitality.
SolarSea AC™: Ocean-Sourced Mineral Support
SolarSea AC™ is a premium seaweed-derived mineral complex that provides naturally occurring trace minerals sourced from marine environments. These minerals help support normal cellular function and contribute to overall wellness. The ingredient also supplies naturally occurring compounds found in sea vegetables that have been valued for their nutritional properties. At Bill & Coo, we choose high-quality ingredient sources because quality begins long before manufacturing.
Quercetin: A Plant-Based Bioflavonoid
Quercetin is a naturally occurring plant flavonoid found in fruits and vegetables. It has become a popular ingredient in wellness formulations because of its antioxidant properties. Many pet owners incorporate quercetin into wellness routines to help support a healthy immune response and seasonal wellness. Combined with complementary nutrients, quercetin helps provide balanced nutritional support for overall health.
Magnesium Oxide: Supporting Everyday Function
Magnesium plays an essential role in hundreds of biological processes throughout the body. It helps support:
Normal muscle function
Healthy nerve signaling
Cellular energy production
Overall metabolic function
Including magnesium helps provide foundational nutritional support for your pet's daily wellness.
NAD (Nicotinamide Adenine Dinucleotide): Supporting Cellular Energy
NAD is a naturally occurring coenzyme found in every living cell. It plays an important role in cellular energy production and supports many normal biological processes involved in healthy aging. As interest in longevity and cellular wellness continues to grow, NAD has become an exciting area of nutritional science for both people and companion animals. At Bill & Coo, we include innovative ingredients that align with emerging scientific research while maintaining our commitment to quality and thoughtful formulation.
Vitamin K2: Supporting Bone Health
Vitamin K2 helps support the body's normal calcium metabolism, which plays an important role in maintaining healthy bones. Working alongside other nutrients, vitamin K2 contributes to balanced nutritional support for skeletal health and overall wellness.
More Than Ingredients, A Thoughtful Formula

Choosing individual ingredients is only part of the process. The real science lies in how those ingredients work together. At Bill & Coo, every formula is carefully designed to provide complementary nutritional support using ingredients selected for quality, purity, and purpose. We never believe in adding unnecessary fillers or ingredients that don't serve a meaningful role. Instead, we focus on creating products that reflect our commitment to clean, functional nutrition.
What You Won't Find
Just as important as what's included is what isn't. Our philosophy is simple:
No unnecessary fillers
No artificial junk
Carefully selected ingredients
Thoughtful formulations
Quality you can trust
Because every scoop should deliver meaningful nutrition, not empty space.
