Ready-to-drink shake with 30 g of milk protein and very little sugar, widely available in many flavours, making it the easiest high-protein option for most people.

AI picks by need
For whole-food ingredient bar
RXBAR Protein Bar (line)
Short ingredient list built from egg whites, dates and nuts with no added sugar alcohols.

For low-sugar, low-net-carb bar
Quest Protein Bar (line)
High protein and fibre with minimal sugar, suited to low-carb eating.
Not for: People sensitive to added fibre or sugar alcohols such as erythritol, which can cause bloating.
For older adults or adding calories
Ensure Original Nutrition Shake (line)
Balanced calories, protein and vitamins designed to supplement intake for people who struggle to eat enough.
Not for: People trying to lose weight or limit sugar, and anyone with diabetes without clinician guidance, who should look at Glucerna instead.

Fairlife Core Power (line)
Ultra-filtered milk protein shake with protein and carbohydrate suited to refuelling after training.
Not for: People with milk allergy and anyone wanting a low-carb or low-calorie drink.
What the AI looks for in Nutrition Bars & Drinks
- Protein per serving
- About 20 g or more for a shake or meal substitute; at least 10 g for a bar sold as a protein bar. Around 20 to 30 g per sitting is the commonly cited range for satiety and muscle protein synthesis; lower amounts are a snack.
- Protein source quality
- Prefer milk, whey, casein, egg, or soy/pea blends; be wary when collagen supplies much of the listed protein. Collagen is incomplete protein, so it inflates the protein number without matching muscle-building value.
- Added sugar
- Check the Added Sugars line on the label; many protein products keep it in single digits per serving, while some bars rival candy. Many bars are candy bars by nutrition profile despite health marketing.
- Sugar alcohols and fibre
- Watch for maltitol in particular, and large doses of added fibre. Maltitol raises blood sugar more than other sugar alcohols and commonly causes gas and diarrhoea.
- Purpose: snack versus meal replacement
- A true meal replacement should provide meal-level calories plus vitamins and minerals; a low-calorie protein shake is not a full meal. Using a low-calorie shake as a meal can leave you hungry and short on nutrients.
- Athlete testing
- Tested athletes should choose NSF Certified for Sport or Informed Sport certified products. These programmes screen for banned substances that could cause a failed drug test.
Brands that matter
- Premier Protein: High-protein, low-sugar shakes at mass-market cost.
- Fairlife: Ultra-filtered milk shakes, including Core Power for recovery.
- Ensure: Calorie and nutrient shakes for older adults and those needing extra intake.
- Quest: Low-sugar, high-fibre protein bars and snacks.
- RXBAR: Simple whole-ingredient bars with egg-white protein.
- Orgain: Plant-based and organic shakes and powders for dairy-free diets.
- KIND: Nut-based snack bars; tasty but generally lower in protein.
- Glucerna: Shakes and bars formulated for people managing diabetes.
What to avoid
- Bars sweetened mainly with maltitol if you have a sensitive stomach.
- Products marketed as protein bars with under 10 g of protein or mostly collagen protein.
- Relying on low-calorie protein shakes as every meal without medical supervision.
- Bars with more added sugar than protein.
- Uncertified products if you are a drug-tested athlete.
Questions
Can a protein shake replace a meal?
A protein shake can stand in for a light meal now and then, but most are lower in calories and fibre than a meal; true meal replacements are formulated with more calories and nutrients.
Are plant protein bars and shakes as good as dairy ones?
Soy is a complete protein, and pea-rice blends work well; single plant sources may need slightly more protein per serving to match dairy.
