Can I consume more than one bottle of BOOST® Drinks each day? BOOST® Drinks may be consumed with meals, or as a snack or mini-meal, and may therefore be consumed more than once per day. A general guideline is up to three bottles per day so that you may enjoy a variety of other choices in your diet. Why doctors recommend BOOST. To achieve or maintain a healthy weight, the calories and nutrients you’re getting through food might not be enough. A supplemental drink can help fill in the gaps with the necessary extra calories, vitamins, and minerals.
