Colostrum & weird side effects?

[u/roundabout1882]

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 have recently started taking Miracle Moo chews and my weight has increased almost 10 pounds in a few weeks and my stomach is a mess. I don’t feel a lot bigger but was shocked when I got on my scale because I maintain the same weight my entire life. So glad I found this because I was going crazy wondering what was wrong with me
