Apollon is always top notch with their products. I started to take colostrum for hair growth but saw the standardization on this version for immune support and needed to try it. I’m on at least my 8th tub and I’ve been incredibly pleased. I have a toddler in daycare so I need all the immune defense I can get. I mix one scoop in the morning and one scoop at night with my protein shakes and it doesn’t disrupt the taste at all. I will continue to buy this as long as it’s available!
