8.0 out of 10

Strong Choice

This supplement is a simple cranberry and vitamin C blend for cats whose owners or veterinarians want to add targeted urinary or immune support on top of a balanced diet. It’s very straightforward, with just three active ingredients. It can be useful when your vet specifically recommends cranberry or extra vitamin C, but it does not replace a complete cat food or medical treatment.

Nutritional Perspective

KibbleLab Review

Strengths

  • The formula is very simple, with just cranberry powder and two forms of vitamin C as the active ingredients.
  • Each 1/4 teaspoon provides a clearly stated 355 mg of vitamin C, which helps with consistent dosing.
  • The bland powder form makes it easy to mix into wet food or water for most cats.
  • It is suitable for cats of any size, as the same dose can be adjusted per veterinary guidance.

Considerations

  • This is a supplement only and should always be used alongside a complete, balanced cat food.
  • High doses of vitamin C can cause stomach upset in some cats, so introduce it gradually and watch for loose stool.
  • Cranberry and vitamin C are not substitutes for veterinary care if your cat has urinary signs like straining, blood, or frequent urination.
  • Safety in pregnant or breeding cats has not been established, so it should only be used under veterinary guidance in those cases.

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.
