Great stuff
I can't really explain it, but it gives your brain a (very prolonged, subtle) extra measure of mental energy, optimism, and patience to articulate your thoughts. I added this product to my random vitamin supplements planning to take only one per day, but I enjoyed the effects enough to double-up and take two. If you're smart, it will probably make you smarter. If you're dumb, it will probably make you happier. It feels like a serotonin boost, basically.
