C:1 | Cellular Support
A full-spectrum blend of CBD, CBDa, THC, and THCa with select terpenes, boosted by Magnesium, B-Complex, and Chamomile - calibrated to help support a normal immune system and healthy cellular function, for dogs and cats.
Why C:1 is different
C:1's blend is formulated to help support a normal immune system and healthy cellular function, for pet parents navigating a difficult diagnosis and looking for a natural, well-tolerated addition to their pet's care. This formula is built around the Entourage Effect, well known in medical cannabinoid science, which brings out the best of the plant to maximize the benefit for your dog or cat.
Right:Ratio's C:1 formula isn't just a standard CBD oil - we've paired full-spectrum cannabinoids with supportive ingredients like chamomile, along with B-complex and magnesium, to help support your pet's overall vitality and comfort, for dogs and cats.
This proprietary blend was painstakingly crafted by veterinary experts with pets of their own, so they could make sure their own loved ones had their best lives at every stage - and now the same formula is available for yours.

What to consider when selecting C:1 for your pet
A good fit if your pet:
- Shows lack of appetite or unexplained weight loss
- Seems low energy or slower to bounce back after activity
- Has skin, coat, or other physical changes you can't otherwise explain
- Your vet has flagged a cellular health or immune concern worth monitoring
Talk to your vet first if your pet:
- Is on other medications
- Has a new or worsening symptom that hasn't been evaluated
- Is a puppy or kitten under 1 year old

Backed by research
A sample of the researchC:1's formula is grounded in the same clinical cannabinoid science behind every Right:Ratio product. The studies below are a representative sample, curated and maintained by the Veterinary Cannabis Society, an independent nonprofit - not written or funded by Right:Ratio.
Research tells the stories
At R:R, our approach isn't static - it's informed by the latest clinical research in veterinary medicine on the use and safety of medical cannabinoids, and our own +8,000 documented CROMs (Client-Reported Outcome Measures). These are not reviews - they're clinical touchpoints we conduct with every serious medical case we've handled in the last 10 years.

Calibrated, not counted.
Most other pet supplement brands compete on milligram count alone. C:1 is calibrated with the right combination of molecules and ingredients, in exactly the right amounts, and in the right ratios - for the exact cellular support your dog or cat needs, alongside specific dosing and titration guidance.
Not a supplement guess. A clinical protocol.
