I've upped my dosage to about 4g per day and have actually noticed a difference in my mental state. Initially, I was using it in conjunction with ECA for fat burning (no noticeable difference) but now I'm starting to like the nootropic effects. On a low carb diet your mind tends to "space out" often so concentration is really not feasible. Upping my ALCAR seems to sharpen my mind and clear my head...
