I don't know if this is true or not, but I also read that when taking free or isolated amino acids, it's best to take it separate from meals, so that it doesn't get mixed in with the other amino acids from food. But I wonder if that's a good idea. It would be interesting to hear what others here feel about it.Yeah I tried reducing the glycine dose and it worked much better now. If I take it away from heavy meals, I make sure the glycine dose is no more than 1g with a cup of coke or warm milk.
