Sorry, I forgot to reply to your message. (Not sure why someone downvoted you.) It's Sunwarrior brand and you can order it from their website. It tastes terrible, like bitter metallic salt, but I usually drink it with a big sip of almond milk and that helps mask the taste better than water or juice or anything else I've tried. Sometimes I get that buzzed feeling, and sometimes I just notice I'm a little more relaxed. I guess it depends on how tired or dehydrated or low on magnesium I am. It's definitely the most noticeable magnesium supplement I've ever tried.
