Pros and cons
Max Protein Nutrition Shake
- 30 g of complete milk protein (milk protein concentrate plus calcium caseinate) in only 150 calories
- 1 g total sugar, 0 g added sugar, and 4 g fiber including a short-chain fructooligosaccharide prebiotic
- 25 vitamins and minerals per carton, including 60% DV vitamin D, 50% DV calcium and 45% DV zinc
- Full nutrition panel and complete ingredient list published on Abbott's own store — no proprietary blends
- Shelf-stable cartons that are gluten-free, kosher and halal, and suitable for lactose intolerance
- Premium price: about $2.83 per carton at Abbott's list price, versus roughly $2 for several comparable 30 g ready-to-drink shakes
- No NSF Certified for Sport, Informed Sport or other third-party sport certification that we could confirm
- Sweetened with sucralose and acesulfame potassium; review round-ups report a thick consistency and a medicinal aftertaste for a minority of drinkers
- Most vitamin and mineral levels are published only as %DV, not absolute amounts, and milk-based so not suitable for vegans
Naked Whey Grass-Fed Whey Protein (Unflavored)
- Single ingredient: grass-fed whey protein concentrate with no sweeteners or additives
- 25 g of protein and 5.9 g of naturally occurring BCAAs per 30 g serving
- Versatile in recipes because it has no flavor or sweetener
- Large review base: 4.3 stars from nearly 11,000 buyer ratings
- Bland, milky taste on its own; most people blend it with other ingredients
- Clumping and foaming are common complaints without a blender
- The NSF Contents Certified claim could not be confirmed in NSF's public listings
- Contains some lactose (2 g sugar per serving), unlike an isolate
Our verdicts
Max Protein Nutrition Shake
For 30 g of complete milk protein in 150 calories with 25 vitamins and minerals and no added sugar, this is a well-constructed convenience shake from a manufacturer with serious clinical-nutrition credentials. It is best viewed as a protein-and-micronutrient top-up for busy days, older adults or low-appetite periods rather than a performance product, since there is no sport certification. Expect to pay more per serving than most 30 g rivals, and buy a four-pack first — opinions on the thick texture and sucralose finish split sharply.

Naked Whey Grass-Fed Whey Protein (Unflavored)
Naked Whey is the simplest way to add whey to your diet: one ingredient, 25 g of protein per serving and a fair price for grass-fed sourcing. It tastes plain on its own and its NSF certification could not be confirmed in NSF's public database, so it suits blenders and bakers better than athletes who need verified testing.
