I took a look at the Ready-to-drink bottles and they’re a little more complete than the powder+milk. Still missing everything that’s not listed, fat’s still low, and you’d be over on a few vitamins. When you look at the price, even in bulk, it appears to be $4/bottle, 4/day, so $16/day.
Edit: That price and analysis is only for the pre-made drinks. What @Brad linked to was the powder version, which is much cheaper, and @Mqrius analyzed.
But I agree with @Mqrius, it’s a pretty good starting point, and while you can’t tweak the recipe, it’s got a lot of good nutrition in there. For what it’s marketed to be (Breakfast replacement), I’d say it’s doing a pretty good job of getting at least some nutrients that most people miss (30% magnesium in 1 bottle is great).
