As a holistic veterinarian, I often see dogs who need extra nutritional support. Even the best commercial diets can leave gaps, especially when it comes to vitamins and minerals that fuel the immune system, digestion, joints, and skin health. That’s why I often recommend Catalyn® by Standard Process.
This supplement was first created in 1929 and has stood the test of time. It’s made from carefully chosen whole foods, preserved in a way that keeps nutrients as close to their natural state as possible. Think of Catalyn as a “nutrient boost” that helps fill in what your dog’s diet may be missing.

What is Catalyn®?
Catalyn is a multivitamin and mineral blend originally developed by Dr. Royal Lee, the founder of Standard Process. His philosophy was simple: whole foods provide the best nutrition when processed gently and kept intact.
For dogs, Catalyn offers:
- A broad spectrum of vitamins and minerals from real food sources
- Support for immune health, skin, digestion, and energy levels
- A safe option for dogs of all ages, from growing puppies to aging seniors

Key Benefits for Dogs
Catalyn provides a wide range of health advantages:
- Immune strength: Packed with antioxidants, vitamins, and minerals that help your dog fight off infections.
- Skin and coat health: Ingredients like vitamin E and fatty acids promote smooth skin and a shiny coat.
- Joint comfort: Helps reduce inflammation and supports mobility, especially in older dogs.
- Digestive support: Whole food ingredients make nutrients easier to absorb and gentler on the stomach.
- Steady energy: Provides balanced nutrition that fuels daily activity.
What’s Inside Catalyn®
Each ingredient was chosen for its unique role in supporting your dog’s body:
- Defatted Wheat Germ: A source of B vitamins and vitamin E for skin, coat, and immune support.
- Carrot Root: Rich in beta-carotene, an antioxidant that protects cells and supports eye health.
- Sweet Potato: High in fiber for digestion and steady blood sugar balance.
- Oat Flour: Adds protein and fiber for strong muscles and gut health.
- Nutritional Yeast: Provides B vitamins essential for nerves, metabolism, and healthy skin.
These superfoods work together to give your dog comprehensive, balanced nutrition in one daily supplement.

How Catalyn® Helps with Specific Issues
Dogs can benefit from Catalyn in many different ways:
- Joint stiffness: Anti-inflammatory nutrients support comfort and flexibility.
- Digestive troubles: Improves nutrient absorption and helps regulate bowel health.
- Weak immune system: Provides protective antioxidants and essential vitamins.
- Skin irritation or dull coat: Supports skin repair and coat shine.
- Low energy: Delivers the nutritional foundation for vitality at every age.
I often combine Catalyn with other holistic therapies like cold laser therapy for arthritis or skin conditions. Nutrition lays the foundation, while treatments like laser therapy help reduce inflammation and speed healing. Together, they create a stronger, more natural approach to health.
Dosage and How to Give Catalyn®
The right amount depends on your dog’s size:
- Small dogs (1–20 lbs): 1 tablet daily
- Medium dogs (21–50 lbs): 1 tablet twice daily
- Large dogs (51+ lbs): 2 tablets twice daily
Tips for giving:
- Offer the tablet as a treat if your dog accepts it.
- Crush and mix into food for picky eaters.
- Give at the same time each day for best absorption.
Always provide fresh water afterward. And as with any new supplement, start slowly and watch for changes in appetite or digestion.

Possible Side Effects and Safety
Most dogs tolerate Catalyn very well. Rarely, you might see:
- Mild stomach upset (vomiting or diarrhea) when first starting
- Signs of allergy such as itching, swelling, or changes in behavior
If symptoms persist, stop the supplement and check with your veterinarian. Overdosing is not helpful and may cause problems, so stick with the recommended dose.
Should You Try Catalyn®?
Catalyn is not a replacement for good food, but it’s an excellent way to strengthen your dog’s nutritional foundation. Whether you’re supporting an active young pup, an aging senior, or a dog recovering from illness or injury, Catalyn can help their body work more efficiently.
