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’ve seen how powerful natural supplements can be for dogs. Cataplex® E2 by Standard Process is one I often recommend because it gives extra support to the heart and muscles while also boosting overall vitality. It’s made with whole-food ingredients and designed to strengthen key systems that keep dogs active and healthy.

What is Cataplex E2?

Cataplex E2 is a whole-food supplement developed by Standard Process, a trusted company in holistic medicine since 1929. This formula was created to:

  • Support cardiovascular (heart and circulation) health
  • Maintain strong, healthy muscles
  • Improve energy metabolism so dogs have steady energy
  • Provide antioxidant protection against cell damage

The unique blend of natural ingredients includes organ extracts, minerals, and plant-based nutrients that work together to protect your dog’s most vital systems.

Ingredients and Why They Matter

Here are some of the standout ingredients in Cataplex E2:

  • Bovine Orchic Extract: Nutrients that may support hormone and reproductive balance.
  • Selenium: A trace mineral that supports thyroid function, metabolism, immune defense, and heart health.
  • Spanish Moss: Rich in antioxidants and anti-inflammatory compounds that protect blood vessels and reduce oxidative stress.
  • Inositol: Supports nerve function, fat metabolism, and may reduce anxiety or help neurological conditions.
  • Whole-food superfoods: Alfalfa, nutritional yeast, and wheat germ provide vitamins, minerals, and phytonutrients for broad wellness.

This formula is carefully balanced so that each ingredient enhances the others.

How Cataplex E2 Helps With Specific Issues

Cataplex E2 isn’t just a general wellness supplement. I’ve recommended it for dogs dealing with:

  • Heart conditions: Helps support circulation, heart muscle strength, and rhythm stability.
  • Muscle weakness or loss: Assists senior dogs or those recovering from illness or surgery.
  • Low energy or poor metabolism: Supports mitochondrial function (the “batteries” inside cells) for steady energy.
  • Weakened immune system: Antioxidants help protect against illness and chronic inflammation.

Cold laser therapy can also be a wonderful companion treatment for dogs with heart or muscle concerns. I often combine nutritional support like Cataplex E2 with therapies that improve circulation and tissue healing.

Dosage and Administration

The right amount depends on your dog’s size and health needs. Always check with your vet before starting.

Typical daily guidelines:

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

Ways to give:

  • Directly by hand (some dogs chew them like treats)
  • Crushed and mixed into meals
  • Hidden in a pill pocket or soft treat

Start with the lowest suggested dose and adjust with guidance from your veterinarian.

Possible Side Effects and Safety

Most dogs tolerate Cataplex E2 very well. Rarely, you may see mild digestive upset (soft stool, vomiting) if given too much at once.

Watch for:

  • Allergic reactions: itching, swelling, hives, or sudden vomiting/diarrhea. Stop use and call your vet if this happens.
  • Interactions with medications: always let your vet know what supplements your dog takes.

Store safely out of reach of pets. Supplements should never replace a balanced diet or regular veterinary care.
