Immune Support for Dogs

The use of bovine colostrum as a supplement goes back thousands of years to Ayurvedic medicine. Colostrum contains over 90 immune factors, including the naturally occurring immunoglobulins IgG and IgA. It provides over 70 different growth factors for cellular support. Bovine colostrum powder provides bioactive proteins, peptides, and probiotics. Our colostrum provides 38% IgG.

Ethically sourced from rBGH-free, grass-fed cows. 

Available in 30 or 120 scoops.

(One scoop = 1 large dog per day)

"Wow! This product made a HUGE difference in my dog's allergies this year. Normally she would be chewing her paws all the time and constantly scratching/itching. Since starting this product, there has been a significant decrease in allergy symptoms. I highly suggest this product to anyone who has a dog suffering from allergies!"- @danicasgsds

Our colostrum is responsibly collected only after the first 12 hours of birth and within a 36-hour time frame, when the colostrum is at its peak. Calves alone receive it during the first 12 hours; after that, it is shared.

I just don't know

I reached out with questions before ordering. BioStar responded quickly and was very helpful. My Lab mix is 11 yrs old and has severe allergies. I was hoping the Colostrum would alleviate the symptoms. I have not noticed any relief yet. All dogs are different and what works for one doesn't always work for another. I am going to wait a little longer and pray it works. I do not want to give him prescription medicine with side effects.

It works!

I originally discovered this product through my groomers. My doodle developed skin allergies at the age of 2 & recently started chewing on his paws. My original goal was to get him off of Apoquel. Once I started him on Colostrum-38 K9 he stopped chewing on his paws & I was able to ween him off of the Apoquel. It’s extremely easy to measure & to mix right in with his kibble along with a little bit of peanut butter. So far so good. I would be amiss if I didn’t mention the downside. Shipping is above the normal cost. I only know this because I run a side business from my home & I am thoroughly aware based on size & weight that this is an exaggerated amount. Hopefully they will eventually realize this.
