Buying Guide
What should I look for in a bariatric protein powder?
Key factors include protein content per serving (ideally 20-27 g), protein source (whey isolate is common), allergen considerations (gluten-free, lactose-free), added vitamins or minerals, and flavor preferences. Texture and mixability are important for comfort after surgery, so options that blend easily with water, milk, or dairy-free milks are desirable.
