Frequently Asked Questions
- Can I give the supplement to a puppy or kitten? Yes, the dosage scales with body weight; however, consult your vet for animals under 4 weeks old.

- Is the product GMO‑free? The formulation uses non‑GMO fish oil and plant‑derived lutein.
- Will the supplement help with chronic ear infections? While it supports overall immune health, it is not a direct treatment for ear infections.
- Can I mix the capsule with wet food? Absolutely – the gelatin shell dissolves quickly, and the flavor of the food masks the capsule.
