The following information is a summary and review based on Dr. Candy’s professional experience and recommendations. Any summary or statement has not been provided nor influenced by the manufacturer.

If you’re a dog parent like me, you know how much we want our pups to stay healthy, active, and comfortable in their own skin. Cataplex A by Standard Process is one of my favorite tools for supporting a dog’s skin, eyes, and immune system in a natural, whole-food way.

Let’s look at what makes this supplement so effective and how it can fit into your dog’s daily routine.

Cataplex A for Dogs by Standard Process

What Is Cataplex A by Standard Process

Cataplex A is a whole-food supplement formulated to support healthy vision, skin, and immune function in dogs. It’s made by Standard Process, a trusted company that has been producing food-based supplements since 1929.

The key nutrient in Cataplex A is vitamin A, a fat-soluble vitamin essential for healthy eyes, skin repair, and immune strength. Unlike many synthetic vitamins, the vitamin A in Cataplex A comes from natural, nutrient-dense ingredients like fish liver oil, carrots, and sweet potatoes. This makes it easier for your dog’s body to absorb and use effectively.

Why I Recommend Cataplex A for Dogs

I often suggest Cataplex A for dogs who struggle with:

  • Dry, itchy skin or dull coat
  • Frequent eye discharge or poor night vision
  • Low immune resilience or slow healing
  • Nutrient gaps in commercial diets

Here’s how it helps:

  • Supports eye health: Vitamin A keeps the retina healthy, reducing risk of night blindness and maintaining clear vision.
  • Promotes healthy skin and coat: It supports normal cell growth and tissue repair, improving skin texture and shine.
  • Boosts immune defense: Vitamin A strengthens the immune response, helping dogs resist infections and inflammation.
  • Supports growth and bone health: Adequate vitamin A helps maintain proper skeletal development and repair.

Key Ingredients and Their Benefits

Each two-tablet serving of Cataplex A includes a blend of natural, food-based nutrients:

  • Vitamin A (as beta-carotene): Essential for vision, immune balance, and skin repair.
  • Organic carrot and sweet potato: Excellent sources of beta-carotene, which the body converts into vitamin A as needed.
  • Calcium lactate: A bioavailable form of calcium for strong bones and muscle health.
  • Defatted wheat germ: Rich in vitamin E and antioxidants that protect cells.
  • Bovine kidney: Provides natural glandular support and trace nutrients that promote healthy organ function.
  • Organic oat flour and nutritional yeast: Sources of B-vitamins and fiber for digestive and metabolic support.
  • Rice bran and sunflower lecithin: Supply healthy fats and fiber for smooth digestion and shiny coats.

All these ingredients work together to support your dog’s body naturally, helping them absorb and use nutrients efficiently.

How Cataplex A Helps Specific Dog Health Concerns

1. Eye and Vision Support
Vitamin A plays a major role in protecting the retina and cornea. Dogs with low vitamin A may show signs like excessive tearing, squinting, or poor night vision. Cataplex A replenishes this vital nutrient to keep eyes healthy and clear.

2. Skin and Coat Health
A shiny coat starts with healthy skin. Vitamin A supports the renewal of skin cells and normal oil production, which helps reduce flakiness, itching, and dull fur.

3. Immune Function and Recovery
I often include Cataplex A in wellness plans for dogs recovering from illness or dealing with chronic allergies. It helps their immune system respond properly to stress and inflammation.

4. Whole-Body Balance
Because vitamin A works closely with vitamins E and D, Cataplex A can be paired with other Standard Process products like Cataplex E, Canine Whole Body Support, or Tuna Omega-3 Oil for a more complete nutritional program.

Dosage and How to Give Cataplex A

The correct amount depends on your dog’s size and current health. I generally recommend:

  • Small dogs (up to 20 lbs): 1 tablet twice daily
  • Medium dogs (21–50 lbs): 2 tablets twice daily
  • Large dogs (over 50 lbs): 3 tablets twice daily

You can give the tablets directly by mouth or mix them into food. For picky eaters, crush the tablet and hide it in a favorite snack like peanut butter or soft cheese.

Tip: Consistency matters. Regular daily use helps your dog get steady benefits over time.

Possible Side Effects and Safety

Cataplex A is generally very safe when used correctly, but a few precautions are important:

  • Vitamin A overdose: Giving too much over a long period can cause toxicity. Symptoms include dry skin, lethargy, or loss of appetite. Stick to the recommended dose.
  • Allergies: If your dog has a wheat sensitivity, monitor for itching or digestive upset, since the formula contains wheat germ.
  • Vet guidance: Always check with your veterinarian before starting any new supplement, especially if your dog is on medication or has chronic health issues.

If you notice any unusual signs, stop the supplement and reach out to your vet.

When I Use Cataplex A in Holistic Care

I often include Cataplex A as part of a holistic plan that may also involve:

  • Cold laser therapy to help reduce inflammation, encourage tissue repair, and support skin healing.
  • Whole-food diet improvements to boost natural nutrient intake.
  • Digestive support supplements like Zypan or Zymex II for better nutrient absorption.

Combining gentle, science-backed therapies with targeted nutrition can make a big difference in your dog’s comfort and longevity.

Regular use helps maintain sharp, healthy vision—especially in older dogs or those prone to eye irritation.

Yes, absolutely. Vitamin A plays an important role in skin cell repair and renewal. Dogs with flaky skin, dull coats, or mild itching often benefit from the added support Cataplex A provides. Over time, you’ll notice smoother skin, a shinier coat, and improved comfort for your pet.

How often should I give my dog Cataplex® A?

The dosage depends on your dog’s size and overall health. As a general guideline is available above.
However, I always recommend confirming your dog’s exact dosage through a holistic vet consultation. This ensures proper balance with your dog’s diet and other supplements.

Are there any side effects associated with Cataplex® A?

Cataplex A is generally safe when used as directed. Because it’s rich in vitamin A, giving too much over time could lead to toxicity. Watch for signs like decreased appetite, dry skin, or fatigue. If you notice anything unusual, stop the supplement and contact your veterinarian.
