10 Best Protein Bars Low Sugar High Protein of 2025

Main Highlights

• 
  PROTEIN SYSTEM: David has 28g of protein and only 150 calories. This is 75% CFP (CFP = Calories from Protein / Total Calories). The most protein-dense bar in existence. A diversity of protein sources comes together for a perfect 1.0 protein digestibility-corrected amino acid score (PDCAAS), meaning this protein is the best amino acid profile for both muscle building and optimal bodily functioning (including skin, hair, and nail health).
• 
  BINDING SYSTEM: The binding system in David forms what would otherwise be protein powder into a bar consistency. In addition to binding, some of these ingredients provide prebiotic gut health benefits. Most importantly, Davids binding system, primarily consisting of Maltitol and Allulose, limits caloric impact and blood sugar responses.
• 
  FAT SYSTEM: The goal of David is to create the highest CFP bar possible (CFP = Calories from Protein / Total Calories), meaning the most protein with the fewest calories. Fat contains 9 calories per gram compared to 4 calories per gram for both protein and carbohydrates. This makes it essential to reduce fat calories in order to craft the best product possible. In addition to coconut oil, cocoa butter, and palm oil, David uses a modified plant to help achieve the texture of fat with fewer calories.
• 
  FLAVOR SYSTEM: The David Flavor System is what gives our bars their delicious taste and sweetness with no calories or impact on blood glucose levels. Key components of the flavor system are cocoa powder, natural and artificial flavors, salt, sucralose, and acesulfame potassium. Natural colors, like carmine and pea flower, are added to some of our flavored bars for visual appeal.

  WHY PROTEIN IS SO IMPORTANT: Protein intake is the foundational of nutrition for 3 key reasons: (1) to increase or maintain muscle and lean mass for optimal functioning now and to avoid injury or weakness as you age. (2) to properly regulate caloric intake, thus helping to avoid excess body fat and manage metabolic health, (3) to support essential bodily functions as protein pays a key role in healthy bones, muscles, skin, hair, nails, and joints.
