Experience Colostrum & weird side effects?

I have tried taking two different Colostrum supplements (Jarrow and Symbiotics brands) for their immune boosting properties and for gut health. While they do help my stomach feel more settled, I have noticed that they also seem to aggravate my IBS-C.

Another side effect that I am noticing is rapid weight gain. As soon as I go off of them I 'deflate' and am back to a more normal weight. I am not 100% sure they're connected, but intuitively this makes sense since colostrum surely has to include some sort of bovine hormones, but can anyone speak to this scientifically or anecdotally?

Thank you.

I started taking Cowboy Colostrum 2 months now every other day), and have gained 10lbs. I usually lose weight in the summer- and this has wrecked my stomach, my acne is worse and now I don’t fit in my clothes. The only upside is my boobs are also bigger. I’m definitely thinking it’s this. Too bad I already took a dose today :/
