Caution: I would advise the use of fresh or frozen fruits and vegetables, lean meats and other real food rather than relying in heavily processed meal replacement beverages. They also tend to be high in sugar, artificial sweeteners and preservatives

Depends: On the vitamin and how much of a deficiency is. For the fat soluble vitamins, such as b-12, can be up to three months.

Hours, if at all: Most vitamins are used or lost within the first hours of consumption. A few of the fat soluble vitamins can be stored, but most water soluble vitamins assist your metabolism as they circulate and end up in the urine the 1st day. If the shake is providing excess vitamin you already have, they are lost with no effect on your system.

Too much sugar! : Please read: http://www.Weightymatters.Ca/2011/10/badvertising-boost-is-it-really.Html?M=1 with 28 g of sugar in this product constituting 43% of the calories, you re getting very little protein in this shake, unless it's been reformulated by nestlé's. All of the corn syrup and sugars are gmo. It also has wheat products so if you're allergic to wheat this is a problem. Any energy that you might perceive you're getting is from the sugar load, not from the protein or vitamins listed.
