"I have an older Belgian mare that was diagnosed with EPM. Colostrum-38 EQ has been part of her recovery/maintenance regime. I have been very pleased with the product. When my vet came out to check on her, we discussed what I was doing for her. I showed what I was using, he read the labels, and said to keep giving her what I was using."  

- Elizabeth C.


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.

Immune system

I like to add colostrum in stressful situations are now coming up in the horse. I have one horse what has summer itch and I feel like the cholesterol helps him to battle that Combination with other things.

Great Product

I've been using this supplement for years. I feel it helps my mare with heat cycle, keeps her immune system functioning well so she heals quickly from any injuries she does to herself. Also helps her gut stay healthy.
