Cataplex® A-C for Dogs: Holistic Vet Guide to Immunity, Skin & Care

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.

As a holistic veterinarian, I look for safe, natural ways to strengthen the body rather than just masking symptoms. One supplement I often recommend is Cataplex® A-C by Standard Process. This formula combines whole-food nutrients, especially vitamins A and C, to give dogs a healthy boost where they need it most: the immune system, skin, eyes, and overall vitality.

Cataplex A-C for Dogs by Standard Process

What is Cataplex® A-C?

Cataplex A-C is a whole-food supplement made with vitamins, minerals, and plant-based ingredients. The focus is on vitamins A and C, two powerful nutrients that:

  • Support healthy skin and coat
  • Strengthen the immune system
  • Maintain eye health and vision
  • Provide antioxidant protection

Standard Process has been producing supplements from whole foods since 1929. Their approach is simple: when nutrition comes from real food, the body can absorb and use it more effectively.

Key Benefits for Dogs

Cataplex A-C can help with a variety of wellness goals. Here are some of the main benefits I see in practice:

  • Immune support: Helps dogs fight off illness and recover from stress, infections, or surgery.
  • Skin and coat health: Vitamin A promotes healthy skin, reduces itchiness, and supports a glossy coat.
  • Eye health: Vitamin A also plays an important role in maintaining vision.
  • Antioxidant protection: Vitamin C and plant nutrients help neutralize free radicals, protecting cells from long-term damage.

Ingredients and Why They Matter

Each ingredient in Cataplex A-C serves a purpose:

  • Vitamin A: Maintains healthy skin, vision, and immune function.
  • Vitamin C: Powerful antioxidant, supports collagen (important for joints, gums, and skin).
  • Calcium: Essential for strong bones, muscle contractions, and nerve function.
  • Carrot root: Provides beta-carotene (a precursor to vitamin A) and antioxidants.
  • Alfalfa: Supplies vitamins, minerals, and plant proteins for balanced nutrition.

This blend is designed so nutrients work together, giving dogs a more complete wellness boost than single-ingredient supplements.

When I Recommend Cataplex A-C

This supplement can be especially helpful for dogs with:

  • Weakened immune systems
  • Frequent skin issues or allergies
  • Dry, flaky coats
  • Age-related eye concerns
  • Dogs recovering from illness, injury, or surgery

I also include it in many holistic health programs where we combine diet changes, whole-food supplements, and sometimes cold laser therapy for immune or skin conditions.

Dosage and How to Give

The general guideline is based on weight:

  • Small dogs (1–20 lbs): 1 tablet twice daily
  • Medium dogs (21–50 lbs): 2 tablets twice daily
  • Large dogs (51+ lbs): 3 tablets twice daily

Tips for giving:

  • Many dogs take the tablets directly as a treat.
  • You can hide them in food or a favorite snack.
  • Try to give them at the same time each day for consistency.

Always check with your vet before starting, since every dog’s needs are different.

Possible Side Effects

Most dogs tolerate Cataplex A-C well. A few may experience:

  • Mild digestive upset (loose stool or vomiting) when first starting
  • Rare allergic reactions (itchiness, swelling, or difficulty breathing)

If you notice any reaction, stop the supplement and contact your vet. Starting with a smaller dose and gradually increasing can help sensitive dogs adjust.
