When our dogs slow down, struggle with energy, or show signs of stress, it can be hard to know how best to help them. Sometimes the root of the problem lies in the nervous system, which controls everything from movement to mood. One of my favorite tools for supporting these functions is Cataplex® B by Standard Process.
This supplement provides a full spectrum of B vitamins from whole-food sources. These nutrients help the body convert food into energy, keep nerves healthy, support digestion, and even contribute to a shiny coat. In my holistic veterinary practice, I’ve seen Cataplex B make a real difference for dogs dealing with fatigue, stress, seizures, or age-related decline.
In this guide, I’ll walk you through what Cataplex B is, how it works, the health issues it can support, and how to give it safely to your dog.

What is Cataplex® B for Dogs?
Cataplex® B is a whole-food supplement from Standard Process that provides a broad spectrum of B vitamins. These vitamins are essential for healthy nerve function, energy production, digestion, skin, and even mood balance.
Standard Process has been creating whole-food-based supplements since 1929. Their founder, Dr. Royal Lee, believed that nutrients are most effective when delivered in their natural, food-based form. Cataplex B has been trusted for decades in both human and veterinary health care.
As a holistic veterinarian, I often use this supplement to support dogs who need extra help with their nervous system, energy levels, and stress resilience.
Key Benefits of Cataplex® B for Dogs
B vitamins are crucial for many body systems. Here are the main ways Cataplex B can help your dog:
- Supports the Nervous System
- B1, B6, and B12 keep nerves functioning properly.
- Helps with nerve signal transmission.
- May benefit dogs with weakness, poor reflexes, or seizures.
- Boosts Energy Metabolism
- Converts food into usable energy.
- Supports stamina for active or working breeds.
- Helps older or recovering dogs feel less fatigued.
- Promotes Healthy Skin and Coat
- B2 and B3 are especially important for skin and fur quality.
- Can reduce flakiness, dryness, or dull coat appearance.
- Aids Digestion and Nutrient Absorption
- B vitamins help release nutrients from food.
- Supports a healthier gut and better nutrient uptake.
- Strengthens Immune Function
- B6 supports antibody and white blood cell production.
- Helps the body fight infection more effectively.
- Supports Brain and Mood Health
- B vitamins help create neurotransmitters (brain messengers).
- May improve focus, memory, and even reduce stress-related behaviors.

Ingredients That Make the Difference
Cataplex B is built around superfood ingredients rich in natural B vitamins:
- Thiamine (B1): Converts food into energy and supports healthy brain and nerve activity.
- Riboflavin (B2): Important for red blood cell production, eye health, and healthy skin.
- Niacin (B3): Aids digestion, promotes skin and coat health, and supports circulation.
- Vitamin B6: Supports serotonin production (a mood-balancing hormone) and immune function.
- Vitamin B12: Vital for nerve health, red blood cell formation, and mental function.
Each works alone but also together. That synergy is what makes whole-food supplements so powerful.
When I Recommend Cataplex® B
I often suggest Cataplex B for dogs dealing with:
- Nervous system issues (weakness, seizures, poor coordination)
- Low energy or chronic fatigue
- Anxiety or stress (environmental or health-related)
- Digestive concerns, poor nutrient absorption
- Dull skin or coat
- Age-related cognitive decline
It’s not a cure, but it’s a valuable support tool that works well alongside diet, lifestyle changes, and—in some cases—cold laser therapy. Laser therapy can be particularly effective for dogs with nerve pain or slow healing, and I often use the two approaches together in my holistic practice.

How to Give Cataplex® B to Your Dog
Dosage Guidelines
Always check with your veterinarian before starting a new supplement. A general starting point is:
- Small dogs (1–20 lbs): 1 tablet twice daily
- Medium dogs (21–50 lbs): 1.5 tablets twice daily
- Large dogs (51+ lbs): 2 tablets twice daily
Easy Administration Tips
- Offer whole as a treat (many dogs love the flavor).
- Crush and mix into food.
- Hide in a soft treat, cheese cube, or pill pocket.
- Use a pill dispenser if your dog tends to spit tablets out.
Consistency matters. Try to give the supplement at the same time each day.
Possible Side Effects and Safety
Most dogs tolerate Cataplex B very well since it’s made from whole food. Rarely, some may experience:
- Mild digestive upset (loose stool, vomiting)
- Temporary changes in appetite or energy
If this happens, stop the supplement and check with your veterinarian. Never exceed the recommended dose unless directed by a professional. If your dog has other health conditions or takes medications, always clear supplements with your vet first.
