Strengths
- Provides vitamin C from three sources, including whole cranberry powder, which can support antioxidant intake.
- Powder form makes it easy to mix with most foods, which can help with consistent daily dosing.
- Non-GMO whole cranberry powder offers phytonutrients with naturally low sugar content.
Considerations
- This is a supplement, not a complete diet, so it must be fed alongside a balanced dog food.

Top 5 Ingredients Explained
01
Cranberry
Cranberries are used in pet foods and supplements as a source of fiber and antioxidants (notably polyphenols/proanthocyanidins) and are commonly included for their potential urinary tract–supporting properties in dogs and cats. While these compounds may help inhibit bacterial adhesion in the urinary tract, scientific evidence in pets is limited, and owners should choose unsweetened, preservative-free preparations (avoiding products sweetened with xylitol), watch for gastrointestinal upset or effects on urine pH, and consult a veterinarian for pets with urinary stones or taking certain medications.

02
Sodium Ascorbate
Sodium ascorbate is the sodium salt of vitamin C often used in pet foods as a stable, water‑soluble antioxidant and as a preserved source of ascorbate to protect fats and vitamins from oxidation. Because dogs and cats generally synthesize vitamin C endogenously, routine supplementation is usually unnecessary, but sodium ascorbate can be used for product stability or specific needs; high doses may cause gastrointestinal upset and the extra sodium should be considered for pets on sodium‑restricted diets.
03
Ascorbic Acid
Ascorbic acid is the chemical form of vitamin C commonly used in pet foods as an antioxidant and preservative to protect fats, flavors, and other vitamins from oxidation and sometimes included as a supplemental source of vitamin C. Dogs and cats generally synthesize vitamin C endogenously so it is not essential in most diets, but added ascorbic acid can support immune function and wound healing and help stabilize the product; large supplemental doses can cause gastrointestinal upset or increase urinary oxalate in susceptible animals, so extra supplementation should be guided by a veterinarian.
04
Other Vitamin
“Other Vitamin” typically denotes one or more vitamins added as part of a vitamin premix to provide essential micronutrients that support metabolism, immune function, skin and coat condition, vision and bone health in dogs and cats. While vitamins are necessary at species‑specific levels (for example, cats require preformed vitamin A), excessive supplementation—especially of fat‑soluble vitamins like A and D—can be harmful, so trusted pet foods follow AAFCO/NRC guidelines and should ideally list specific vitamins and amounts.
