As a holistic veterinarian, I know how important it is for pet parents to find safe, natural ways to support their dog’s long-term health. One supplement I often recommend is C Synergy® by Standard Process. This blend of whole-food nutrients and superfoods can make a big difference for dogs who need stronger immune function, healthier skin, or extra support as they age.
Let’s walk through what it is, how it works, and how it may help your dog.

What is C Synergy?
C Synergy is a natural supplement designed to support your dog’s immune system, skin, and overall wellness. Instead of using isolated synthetic vitamins, Standard Process combines nutrient-rich foods, botanicals, and extracts that work together (this is called “synergy”).
Key ingredients include:
- Organic rose hips: A natural source of vitamin C to strengthen immunity and support skin and joint health.
- Green tea extract & turmeric: Powerful antioxidants that protect cells from damage and calm inflammation.
- Medicinal mushrooms (reishi & shiitake): Help balance the immune system, support liver health, and increase resilience to stress.
- Echinacea root: Enhances natural defenses and shortens recovery time from illness.
- Veal bone extract: Provides proteins and minerals to support strong bones and joints.
- Bovine adrenal: Supports healthy stress hormone balance, which can benefit anxious or easily stressed dogs.
- Buckwheat & wheat germ: Sources of vitamins, minerals, and flavonoids that aid digestion, circulation, and skin health.
Key Benefits for Dogs
Here are the main ways C Synergy can help:
- Immune support: Antioxidants and immune-balancing herbs strengthen natural defenses.
- Healthy skin & coat: Vitamin E, rose hips, and fatty acids promote softer skin and reduce shedding.
- Joint & bone support: Veal bone extract and anti-inflammatory ingredients improve mobility.
- Digestive health: Fiber and plant compounds help maintain a healthy gut environment.
- Stress resilience: Mushroom extracts and adrenal support help dogs handle everyday stress.
- Energy & longevity: Whole-food nutrients fuel active dogs and support senior pets as they age.

When I Recommend C Synergy
I often suggest C Synergy for:
- Dogs recovering from illness or surgery
- Seniors who need joint, immune, or skin support
- Active dogs who burn through nutrients quickly
- Pets prone to seasonal allergies or skin flare-ups
- Dogs under stress (moving, boarding, anxiety triggers)
In some cases, I combine C Synergy with other therapies, such as cold laser therapy, for pets who need extra support with inflammation, mobility, or recovery.
Dosage & How to Give
General guidelines (twice daily):
- Small dogs (1–20 lbs): 1 tablet
- Medium dogs (21–50 lbs): 1.5 tablets
- Large dogs (51+ lbs): 3 tablets
Tips for giving:
- Offer the tablet like a treat (many dogs take it easily).
- Crush and mix into food if your dog is picky.
- Give with meals if your dog has a sensitive stomach.
Consistency matters—daily use leads to the best results.

Possible Side Effects
C Synergy is very safe, but a few things to keep in mind:
- Some dogs may have mild digestive upset (loose stools, gas) when first starting.
- Rarely, allergic reactions can occur (itching, swelling). Stop use and call your vet if this happens.
- Always start with a smaller amount for sensitive dogs, then increase to the full dose.
My Take as a Holistic Vet
I’ve seen many dogs thrive with C Synergy added to their care plan. It’s not a replacement for good food, regular checkups, or other treatments, but it can be an excellent layer of support.
If you’d like personalized guidance, I offer online holistic consultations where we can review your dog’s diet, lifestyle, and health needs to decide if C Synergy—or another supplement—is the right fit.
