Honestly it's hard to know if this is doing anything or not, but I feel like it is. It's really hard to quantify things like "am I digesting better?" or "is my memory better?" or "am I less depressed?". But after taking one of these per day for the past 30 days, I do feel like the answer to all of these is "yes". I do seem to have better gut health (combined with taking acacia fiber), and my memory does seem better (though I'm eating better), and my emotional health seems pretty balanced despite a lot of stressful things happening at once. So while it's hard to quantify whether or not the L-Glutamine is the cause for a slightly improved overall health, it at least doesn't seem to have a negative effect! And I do believe it is helping to some degree, especially in terms of gut health. Maybe I should be taking more of a daily dose, but I feel this is having a good impact without being potentially dangerous, so I plan to keep it up!
Edit: 5 months since my initial review, I'm upgrading my ranking from 4 to 5 stars. I now notice definite benefits when taking this supplement. Now that I've begun working out regularly, I feel it really helps with muscle growth and recovery time outside of just taking protein shakes. In general, I can feel the difference on days I take this versus days I don't.
Edit 2: It is now about 16 months since my initial review, and I can confirm that my health is different on weeks where I remember to take this versus weeks when I don't. My mental clarity, muscle growth, and digestive health all improve when I take one of these per day for a few days straight. I'm not always perfect with recording data, but after this much time I have developed a pretty good correlation with this improving my health. One caveat is that if I manage to remember to take this, I also probably remembered to take vitamins, fish oil, and maybe some fiber supplements during that same week. So I still cannot 100% prove that this alone is causing my health, but I do believe it's a critical part of it.
