Tear Stain Supplement Soft Chews
Verified Jun 8, 2026
This is a soft chew supplement for dogs and cats over 12 weeks of age, aimed at supporting eye health and normal tear production rather than serving as a regular food. It uses ingredients like lutein, cranberry extract, eyebright herb, and flaxseed-derived omega-3 and -6 fatty acids to support the eyes, mucous membranes, and immune system. It’s designed to be used alongside your pet’s normal complete diet.
This is a reasonably well-formulated tear-stain supplement for dogs and cats, relying on a mix of botanicals, antioxidants, and fatty acids to support eye and immune health. The active ingredients are present in defined amounts, and the chew base uses fairly standard supplement excipients. As with any supplement, it should be viewed as an adjunct to, not a replacement for, good nutrition and appropriate veterinary care, especially if tear staining is new or worsening.

At a Glance
KibbleLab Review
Strengths
- Clearly listed active ingredients with specific amounts, including cranberry extract, Oregon grape root, vitamin C, lutein, and eyebright herb, which can support antioxidant status and eye health.
- Includes omega-3 and omega-6 fatty acids from flaxseed, which can help support skin and mucous membrane health.
- Soft chew format is usually easy to give and can work well for both dogs and cats over 12 weeks of age.
- Free of common protein allergens like chicken or beef in the active ingredients, which may be helpful for pets with food sensitivities, though the yeast and flavoring could still be an issue for a few individuals.
Considerations
- This is a supplement only and does not provide complete and balanced nutrition, so it must be used alongside a regular, balanced diet.
- Brewers dried yeast and natural flavoring can trigger reactions in a small number of sensitive pets, so monitor closely if your pet has a history of food reactions.
- Herbal ingredients such as Oregon grape root and eyebright herb can interact with certain medical conditions or medications; it’s wise to check with your veterinarian before starting, especially for pets with existing health issues.
- The product is meant for pets over 12 weeks of age, so it’s not appropriate for very young puppies or kittens.

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
Oregon Grape Root
Oregon grape root is an herbal botanical sometimes added to pet supplements and functional treats as a bitter tonic with mild antimicrobial and anti-inflammatory properties (it contains berberine), traditionally used to support digestion, liver function and skin health. It may offer supportive benefits for dogs and cats with digestive or dermatological conditions, but can cause gastrointestinal upset, interact with certain medications (including drugs metabolized by cytochrome P450 and anticoagulants) and is generally avoided in pregnant or nursing animals, so consult your veterinarian for appropriate dosing and safety.
03
Calcium Ascorbate
Calcium ascorbate is a buffered, calcium‑salt form of vitamin C used in pet foods primarily as an antioxidant and mild preservative and sometimes as a supplemental source of vitamin C. While dogs and cats typically synthesize their own vitamin C so routine supplementation is not required, calcium ascorbate can support antioxidant defenses, immune function and collagen formation during stress or illness, and formulators should account for the added calcium and avoid high doses that could cause gastrointestinal upset or alter urine pH.
04
Eyebright
Eyebright is an herbal botanical occasionally added to pet supplements or functional treats for its traditional association with eye and respiratory support, providing plant-derived antioxidants and mild anti-inflammatory compounds rather than meaningful macronutrients. Its nutritional value for dogs and cats is limited, and while it may offer some supportive effects, evidence in pets is sparse; owners should be aware of possible sensitivities, interactions with medications, and consult a veterinarian before use, particularly for pregnant or nursing animals.
05
Marshmallow Root
Marshmallow root is an herbal ingredient sometimes included in pet supplements and foods for its mucilage content, which can soothe irritated mucous membranes and support mild gastrointestinal or respiratory comfort rather than serving as a significant source of nutrients for dogs or cats. It may help calm digestive or urinary irritation, but can slow or reduce absorption of oral medications and should be used under veterinary guidance with attention to dosing, quality, and any pregnancy, metabolic, or drug-interaction concerns.
