I will try and keep this as concise as possible, but holy cow.
For some time now (years) I have struggled with recovery relative to what I once was able to tolerate training-wise. Over the past two weeks I have started taking 5 g glycine on an empty stomach about 2 hours after my post workout meal and I can feel a discernible state of “mental relaxation” set in in less than 20 minutes of consumption. For the first time in I can’t remember how long, I am not having nearly as much trouble falling asleep and staying asleep throughout the night. I am waking up refreshed, without brain fog, and noticeably less irritable in the evenings. Even some nagging injuries seem to be making marked improvements in a short time-frame.
I went from struggling to recover from low to moderate volume/intensity 3 days per week, to having trained 6 out of the last 8 days and currently feeling 100%. I actually had to talk myself out of going today to not push my luck.
I have a couple hypotheses as to why it has helped, but wanted to get CT’s opinion on the possible mechanism(s), and whether or not he has seen such a radical improvement with any of his clients after the addition of glycine?
Some potentially relevant background info:
-Your neurotype questionnaire has me as a Type 3
-Type 3 description fits with a lot of my personality traits, but not at all with the way I like to train
-I can pinpoint, almost to the day, when my recovery tanked some years ago after a “stressful life event”
-No other changes in diet, training, life, etc.
