Bovine Colostrum

Sale price

Free Shipping On Orders Over $49

Rich in immune-boosting antibodies and proteins. Colostrum helps promote a healthy gut and immune system.

Colostrum is the critical mother's first milk. But it's not just for babies. Colostrum is a good source of IgA antibodies, which can help strengthen and balance the gut and immune system. Four Leaf Rover Colostrum is also rich in proline-rich-polypeptide (PRP), which has been shown to help eliminate or improve the symptoms of allergies and other autoimmune conditions.

Four Leaf Rover Colostrum comes from 100% grass-fed cattle from New Zealand. Every batch is third-party tested to be free of antibiotics and growth hormones. Our colostrum is ethically harvested ... it comes from small family dairy farms and is shared with the calves so they can also reap the immune benefit.

bovine colostrum ingredients


Give Four Leaf Rover Bovine Colostrum once or twice a day. Colostrum should be given away from meals but can be mixed in a little broth or kefir.

Where does colostrum come from?

Four Leaf Rover Bovine Colostrum is a powdered form of bovine first milk. It comes from grass-fed, pasture-raised, antibiotic-free & rBGH growth hormone-free cows, raised in a small organic dairy co-operative.

How is colostrum collected?

Colostrum is collected after the first 12 hours of birth and within the 36 hour timeframe when colostrum levels are the highest. Calves alone receive it during the first 12 hours, then it’s shared for collecting. Calves are not separated from their mothers during this process because the quality and quantity of the milk increase when a cow is allowed to raise her calf.

How does colostrum work to help fight my dog’s allergies?

Research has identified an ingredient called proline-rich polypeptide (PRP) as one of the main components of Colostrum that can help with allergy symptoms.

Colostrum can also help regulate the thymus gland and immune cells (T and B cells) and supply immunoglobulins (IgG and IgA) that help promote a healthy gut lining and immune response.

Can my dog take Colostrum if he has a dairy or beef sensitivity?

The proteins in colostrum are different than those in beef. If your dog has a beef sensitivity, he may tolerate colostrum. 

Unlike milk, colostrum only contains small amounts of lactose. But if your dog has a sensitivity to the proteins in dairy, check with your vet before giving colostrum.

How do I give my dog Colostrum?

Colostrum can be given to your dog at mealtime but it’s best given at least 20 minutes before meals for better absorption. You can mix it with a small amount of spring water, organic kefir or broth. Since it’s a part of “Mother’s Milk”, most dogs are happy to eat it and enjoy the flavor.

Can I use Colostrum topically?

Yes! Mix colostrum with some distilled water to make a paste and apply it to hot spots, irritated skin and bug bites. 

Is there research on the benefits of Colostrum?

Yes, there is plenty of research on colostrum. Here's a sample:

    Best. Supplement. Hands. Down.

    You want to talk about a dog with BAD allergies? Sign Lu up. I’ve struggled with allergies from when he was 3 months old to 1.5 years old. When he was a puppy he started itching under his arms and lost all hair there. He then began to cut himself, because he was scratching SO much and kept rubbing his lips and eyes. Lost all the hair there too. Was whinning all the time and not comfortable. He also started to lick his paws and have liquid like BM. I did food allergy testing, switched proteins, dog food brands, Benadryl, Apoquel (which worked, but I was very afraid of long term effects and usage), coconut oil, apple cider vinegar, oatmeal baths, EVERYTHING. He seemed to get a little better but always regressed. I have no idea how I found this site, but I saw the powder and read the reviews. I was PRAYING this would be the thing to help my pup. It took a few months, but the hair started to grow back, he didn’t whine as much, quit licking his paws, wasn’t getting ear infections twice a month, and had solid BM. This supplement changed our lives and he’s able to go outside and live his best life now! Forever grateful for a more natural route, and a powder that gave my dog enjoyment of life back. 10/10 recommend this to EVERY dog owner who struggles with their dog having allergies. It has given me hope.

    Fleas and skin irritation!

    My dog is highly allergic to fleas and I have tried to get rid of them the natural way but it isn’t working. I finally broke down and purchased a flea medication that is used between the shoulder blades but, so far that hasn’t worked either. I’m going to apply the second dose at the beginning of the up coming month but if I can’t rid my house of fleas, I don’t know what I’ll do. In the meantime, the bovine colostrum has kept her skin from getting worse (she rips out her hair and she gets terrible skin irritation and open wounds from licking and biting at fleas) and appears to be healing the worst areas. I will continue using the coliseum even after we remove the problem of fleas because she is 13 and has developed “old doggy” skin sensitivity. I’ll know better how it’s working once we can remove the source of her problem; fleas. Ugh!

    Good stuff!

    I started using colostrum with my dogs to help minimize skin issues related to environmental irritants & flea bite dermatitis. Since giving them colostrum their skin issues have resolved. Even with seasonal increases in environmental irritants their skin remains clear with no itching, rashes or signs of dermatitis that in the past led to open sores often needing antibiotics to heal.

    It worked so well clearing up these skin issues that I now give it to them daily, to help support their overall health & immune system in general.
