Ingredient concerns
- Menadione Sodium Bisulfite Complex (high concern): Menadione (vitamin K3) is a synthetic form of vitamin K that has been banned for use in human dietary supplements in many countries due to toxicity concerns, including potential liver damage, allergic reactions, and cytotoxicity. It can cause oxidative damage to cell membranes. Natural forms of vitamin K (K1 from plants, K2 from bacterial fermentation) are considered safer alternatives. Despite these concerns, it remains widely used in pet food as an inexpensive vitamin K source.
- Sodium Selenite (low concern): Sodium selenite is an inorganic form of selenium with a narrower safety margin than organic forms (such as selenium yeast). It has lower bioavailability and higher potential for toxicity at elevated levels compared to organic selenium sources. Some premium pet foods use selenium yeast instead as a safer alternative.
Dry food, grain-free, for the adult life stage.
