I keep on trying colostrum off and on, and I don’t think it is that bad. I know the doctor right now wants me to take 1 cap of l-glutamine a day, small dose. I might ask him about the colostrum on my phone consult next week. Currently, I am just trying to decided on the sf722. I get depressed, angry, gas, bloating, tired, major die-off from it. The gas and bloating from it are awful, and then I feel like I react to everything. Yesterday, I pretty much just ate veggies all day, and drank some herbal teas just to give my gut a break, no protein yesterday, not even eggs. I just do not think it is that great for me. I have to ask him about that, too. Good luck, but I do not see the harm in doing both l-glutamine and colostrum.
