>>33371470Me again (the questioner). I would recommend simplifying your current stack and later putting back what is really needed. My reasoning is that some of them might be conflicting with others. Also, the more things you take the harder your kidneys and liver will work getting them out, and who knows the long term effect of that. Top of your list is anxiety and l-theanine has been demonstrated good for that (traditional calming use of green tea). L-theanine with caffeine has been scientifically shown to be a significant nootropic. It makes me alert and calm for sure. 50-100mg in a cup of coffee. I would avoid coffee in the evening because of possible sleep disruption. The other things have certain benefits for certain categories of people (older, for example, or with heart conditions). I think you're better served by taking the "simplify first" approach and observe your response before adding anything else.
For brain fog I would look into diet and eating pattern, first. Look up glucose goddess on YT. The tldr is to eat green and colored veggies first, then followed by fats and proteins and carbs last. I confess I tend not to do that, but then again I'm not the one suffering brain fog. An additional thing I do is add a bit of glycine to coffee and no added sugar in anything. Glycine plus NAC is "glynac" and has been shown to strongly reduce inflammation in older people (me) by elevating glutathione production, but the benefits for young people are unproven. Any effects on mental health are unproven.
