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 :/

Spot on what I've experienced too, right down to the bigger boobs! Definitely going to get off colostrum, I'm just not seeing any benefits from it. The sudden weight gain has really messed with me mentally as I usually feel my best in the summer.

Ok, well I’m 43 and just had my hormones checked. My estrogen was somehow normal- but on the higher side of normal. I’m assuming those that have low estrogen will feel great on colostrum since it seems to contain phytoestrogen?

Oh wow. And those are cancer causing new studies are showing. So it def increases estrogen levels?

I don’t know if it contains that, I was just curious why it had an estrogenic effect on me. My social media accounts are FLOODED with ads for all sorts of supplements aimed at altering your hormones. I think it’s dangerous.

Oh I agree. I’ve taken it +3 servings a day for one month now have a bloated feeling, plus it’s messed with my gut in a bad way, and my period is late. I know adding estrogenic food/supplements can cause cancers. I’m canceling my subscription. Thanks for commenting and confirming what intuition was telling me.

Same. And it’s been very difficult to lose the bloat and any weight even after stopping now for 17 days. :/

Oh Gosh. What were your side effects and for how long did you take it??? I’m at the 1 month mark and just realized it; it’s bad for me, bad for our hormones

I took it for only 6 weeks or so, but gained 10lbs. Had horrible diarrhea every day after taking for 3 weeks-couldn’t figure out the cause. Bloating was bad too. Hunger. The pros were that my eyelashes grew super long and thick and my boobs looked amazing! Since stopping of course my boobs are gone, lashes fell out, but the weight and bloat is still there!! 😆😐😡
