actually two things that you can take that greatley helped me in the energy derpartment are Barley powder as in one of those green powders then you are getting a great source of minerals and it's natural not even to mention the alkalizing benefits and the high level of chloryphyll that is in theses green drinks.
Another thing I take is a good alkalizing mineral powder that you mix with water mine contains potassium etc. But I think you can only get it in the country I live in (Sweden) it's called Urbas. But you should be abe to get alkalizing mineral soultions that don't contain any extra crap where you are at or just check out the net. Even thouhg Iprefer to take things that are all natural and thats why I looove the barley my body really needs the extra kick right now so Itake the alkalizing powder.
