I beleive that Colostrum FM has been doing wonders for my immune system since I started taking it a few months ago. Earlier this year I was beset by 2 heavy bouts of flu which it took me weeks to get over. Both times, my candida symptoms got much worse when I had the flu. Since I took colostrum I recently got ill again but this time I got over it much quicker, the illness was much less severe, and there was no candida flare up.
