    Die off or intolerance

    Posted by tigercho on Aug 29, 2012

    This component of colostrum is usually used with a malfunctioning immune system. It was supposed to help me with dysbiosis and infections, but only gave me diarrhea and cramps...Couldn't wait for more than a week

    I am still on the fence about Transfer Factors. You have to use a lot of this product to make any difference. It is cheaper than the 4Life stuff. My opinion is that it is just a form of colostrum not anything unique. Colostrum is a good supplement for immune health.

    Not for sensitive tummies

    Posted by Reviewer2414278 on Oct 04, 2008

    This is probably a very good product - but I got tummy trouble when taking a capsule (following recommendations, 30 mins before food). It might work if I take it with a meal. I also gave some to my dog and she too seemed to experience some nausea, so have discontinued it.
