Bariatric  Advantage High Protein Supplement Mix (formerly High Protein Shake Mix) is  a delicious way to support the protein requirements of bariatric patients by delivering  20 g of high-quality protein from 100% whey isolate, and 1 g of sugar.  Available in Vanilla and Chocolate flavors. 
Protein is a major functional and structural  component of all the cells of the body. Deficiency of this important macronutrient  is common after bariatric surgery as dietary intake of protein is generally  reduced following procedures. Studies have  shown that even 12 months after bariatric surgery, many patients do not get the  minimum recommended daily protein intake of 60 g/day.1
ASMBS guidelines for post-surgical  bariatric patients call for a minimum protein intake of 60 g/day and up to 1.5 g  per kg of ideal body weight per  day, with higher levels to be assessed on an individualized basis.2  Other bariatric clinical guidelines state 70-120 g per day as likely more  adequate, while some patients may need >100 g of protein per day based on  procedure and body weight.2,3
