A little extra backup for the gut, immune system & skin.
Four Leaf Rover Bovine Colostrum is a single-ingredient supplement made from 100% grass-fed New Zealand bovine colostrum. It naturally contains antibodies, lactoferrin and growth factors that support a healthy gut, balanced immune response and normal skin health.
It’s the first milk a mother cow makes for her calf.
Colostrum is naturally packed with antibodies and other protective compounds designed to give a newborn calf early nutritional and immune support.
Those same naturally occurring compounds are why bovine colostrum is used as a daily supplement for dogs. Think of it as concentrated whole-food support for the gut, immune system and skin.
Because where it comes from matters.
Calves come first.
The small farmers supplying this colostrum make sure calves receive the colostrum they need during their first 12 hours before any remaining colostrum is collected.
100% grass-fed.
The colostrum comes from pastured cattle raised in New Zealand, where grazing is part of everyday farm life.
Nothing extra.
The only active ingredient is New Zealand bovine colostrum. No fillers or complicated ingredient list to decode.
Third-party tested.
Every batch is third-party tested and is made without added growth hormones or antibiotics.
What makes this one different?
One ingredient. That’s it.

No giant ingredient panel. No mystery blend. Just colostrum, with sourcing you can actually understand.

🐾 Frequently Asked Questions
🐾 Where does the colostrum come from?
Our colostrum is collected from grass-fed, antibiotic- and hormone-free cows in New Zealand. It’s rich in antibodies and nutrients that support overall health.
🐾 How is it collected?
Calves get all the colostrum they need for the first 12 hours before any collection begins. Calves stay with their mothers — ensuring an ethical, humane process. The colostrum is then gently freeze-dried to preserve nutrients.
🐾 Can it support gut health?
Yes! Colostrum’s immunoglobulins (IgG, IgA) and proline-rich polypeptides help strengthen the gut lining and support a balanced immune response.
🐾 Can dogs with beef sensitivities take colostrum?
Many dogs with beef sensitivities tolerate colostrum since the proteins differ. Start with a small amount, or consult your vet if unsure.
🐾 How should I give it?
For best results, give at least 20 minutes before meals. It can be mixed with a small amount of broth or spring water.
🐾 Should I store it in the fridge?
No refrigeration is needed, but store in a cool, dark place away from heat.
🐾 Is it pasteurized?
No — it’s freeze-dried to retain beneficial immunoglobulins and bioactive compounds for maximum potency.
