Watched ingredients get highlighted on every product panel you open.
- Where it comes from
- Fermentation and synthesis.
- Why it's in the product
- Antioxidant. Note that dogs and cats synthesize their own vitamin C, so this is a bonus rather than a requirement.
- Safety and toxicity
- Safe. Excess is simply excreted.
- Interactions and who should be careful
- Very high doses acidify urine, which is relevant in opposite directions depending on the type of bladder stone a pet forms. Worth a vet conversation if your pet has a stone history.
