Costco has good variety at these same prices ($18 for 32 oz, 36oz), tried pretty much all of them. none of them taste as good as this brand. i can tell it has real vitamins cause when you drink a lot, and your urine is yellow, that means excess vitamins went through your system that the body couldnt absorb. liquid vitamins in general have 80% absorption, hard pills are around 10%/20% (i forgot). plus there's a few exotic algae in here too.
