Yup – so you see what I mean… for you, the glutamine upon going higher (with flush niacin) was starting to do well, but for him with too much use, it starts becoming a burden trying to process, given he likely had more oxidative stress and low pH in key regions… this issue, aside from the very first time (like a flush to the intestines down the stomach) when the upper gut and intestine start rectifying on the real at warp speed, will not happen with the acetylated glutamine, which — with flush niacin — you can start at lower level to evaluate and see.
