Straightforward info so you can feel great about what goes in their bowl.

How does Internal Defense help with fleas and ticks?

By strengthening the immune system and supporting skin and coat health, Internal Defense makes pets naturally less attractive to pests. If a bite does occur, a strong immune system also helps the body respond more quickly and effectively.

Can I use it on its own?

It can help on its own, but Internal Defense is designed as Tier One of The Resistance system. For best results, pair it with Herbal Shield, Topical Defense, and Environmental Defense for layered protection.

Is it safe for both dogs and cats?

Yes. Internal Defense is formulated for both dogs and cats when given at the recommended serving size.

Is it safe for puppies and kittens?

Yes, it can be used for puppies and kittens over 12 weeks old. Start with a smaller serving and increase gradually.

What about beef allergies and colostrum?

Colostrum comes from bovine sources. Pets with a confirmed beef allergy may not tolerate it. If you’re unsure, introduce slowly and monitor closely, or consult your veterinarian before use.

Will the yeast ingredients cause yeast problems?

No. Nutritional yeast and yeast beta glucans are inactive and do not feed candida or contribute to yeast overgrowth. Instead, they provide immune-boosting compounds and B vitamins.
