I have a big doubt it there really some IgG. I used to take some American colostrum brand 35% IgG and didn't get sick even during the high season of flu last few winters. I noticed 65% IgG and Swiss made and was convinced the supplement must be even better and support Swiss local producers is in my priority but in a week taking Wow Cow got sick, got cold with fewer and sniffles, I was so disappointed. I would never buy this supplement again.
Dear Taisiia,
Thank you for your feedback and for supporting Swiss producers. I understand your disappointment at becoming ill after switching from a product you had a positive experience with.
To address your concern directly: the batch you received contains 68.7% IgG, exceeding the declared 65%. We have been pioneers in colostrum for over 20 years and stand firmly behind the quality of our Swiss colostrum.
You received your capsules exactly one week ago. Colostrum is a food supplement, not a medication or an immediate shield against infection. Research on colostrum and respiratory health has examined supplementation over several weeks. It would therefore be misleading to promise protection within a few days, regardless of the brand or country of origin.
Timing also matters: influenza symptoms typically appear 1–4 days after infection. If your symptoms began shortly after starting the capsules, you may already have been infected beforehand. We cannot establish this without knowing when your symptoms started or which infection you had.
Becoming ill during that week does not call the measured IgG content into question, nor does it establish that another product is superior. Similarly, remaining healthy while taking another brand does not prove that it prevented illness.
We stand behind our product with experience and measurable quality. We also believe in honest expectations: no colostrum product can guarantee that you will never become ill.
I would be happy to answer any further questions, and I hope you feel better soon.
Kind regards,
Sven Altorfer - Founder - SWISS WOW COW
