Sure will. Drinking my second shake of the day even while typing this It's been making those 13 hour teaching days a lot more possible. Another observation... I've tried a few other protein/ multi-vit supplements and this is the only one that doesn't taste just irredeemably NASTY! OK, it's pretty nasty by itself in water, but quite palatable in a shake with soy milk, cocoa, a little honey, and sometimes a banana. This is not to be underestimated as a point in its favor!
