Cataplex® C for Dogs by Standard Process: Immune Care and Prevention

When a dog is fighting an infection, dealing with inflammation, or under physical or emotional stress, I always look for ways to support the body instead of forcing it. One of the most effective and gentle ways to do that is with whole food based nutritional support.

Cataplex® C is one of the supplements I reach for often. I use it to support immune function, skin and connective tissue health, and bone strength. I have used it with puppies, adult dogs, and seniors, especially when the immune system needs extra support.

This article walks you through what Cataplex® C is, how it works, and when it can be helpful for your dog.

What Is Cataplex® C for Dogs?

Cataplex® C is a whole food vitamin C supplement. Unlike synthetic vitamin C, this formula provides vitamin C as part of a natural food matrix, along with minerals, glandular tissues, and plant compounds that help the body use it properly.

Standard Process has been producing whole food supplements since 1929. Their approach focuses on nutrient synergy, meaning the ingredients work together the way they do in nature.

I have relied on Cataplex® C for years because it supports the body instead of overriding it.

What Cataplex® C Supports in Dogs

I most often use Cataplex® C in dogs that need extra immune or tissue support. Its benefits extend well beyond basic vitamin C.

Immune System Support

Vitamin C plays a role in white blood cell function. Calcium helps power those immune cells so they can respond appropriately. Echinacea and medicinal mushrooms provide additional immune modulation, meaning they help balance immune activity rather than overstimulating it.

Skin and Connective Tissue Health

Vitamin C is required for collagen production. Collagen is the structural protein found in skin, joints, blood vessels, and connective tissue. When dogs struggle with slow healing, skin issues, or joint wear, collagen support matters.

Bone and Structural Support

Cataplex® C contains veal bone PMG™ extract, veal bone, and bovine bone. These provide minerals and tissue factors that support healthy bone formation and maintenance.

Cardiovascular and Adrenal Support

The B vitamins from nutritional yeast support heart health and energy metabolism. Bovine adrenal tissue supports the adrenal glands, which help dogs cope with physical and emotional stress.

Antioxidant Protection

Organic reishi and shiitake mushrooms, echinacea, vitamin E, and natural vitamin C work together to help neutralize free radicals and manage inflammation.

Ingredient Breakdown and Why Each Matters

Veal bone PMG™ extract
Supports bone marrow function where white blood cells are produced and provides bioavailable calcium.

Bovine adrenal
Naturally rich in vitamin C, proteins, and electrolytes. Supports the stress response and adrenal health.

Nutritional yeast
A natural source of B vitamins that support energy production, heart health, and metabolism.

Organic buckwheat and organic alfalfa
Provide plant based antioxidants, natural vitamin C complexes, and vitamin E.

Organic reishi and shiitake mushroom powders
Support immune balance and antioxidant activity.

Echinacea angustifolia and echinacea purpurea roots

When I Use Cataplex® C With Dogs

Cataplex® C is versatile. I commonly use it for the following situations.

Immune Challenges

I use it with puppies facing serious infections, including parvo, as well as adult dogs dealing with skin infections, chronic inflammation, or parasite stress.

Joint and Bone Support

Vitamin C is essential for collagen synthesis within joints. This makes Cataplex® C helpful for aging dogs, active dogs, and those prone to stiffness.

Skin and Coat Health

Healthy skin cells rely on adequate vitamin C and collagen formation. This supplement can support dogs with dull coats, slow healing, or recurrent skin issues.

Dosage and Administration for Dogs

Proper dosing helps maximize benefits while minimizing digestive upset.

General Dosage Guidelines

These are general guidelines. Individual needs may vary based on health status and goals.

How to Give Cataplex® C

Tablets can be given by hand, mixed into meals, or hidden in food. For picky eaters, tablets can be crushed and mixed into wet food or broth.
