David uses a four-system formula: a complete protein blend (milk protein isolate, collagen, whey concentrate, egg white), modified plant fat (EPG) that provides texture with 92% fewer calories than regular fat, low-glycemic sweeteners, and a binding system that keeps blood sugar stable.

PDCAAS (Protein Digestibility-Corrected Amino Acid Score) measures protein quality on a scale of 0 to 1.0. David Bar scores a perfect 1.0, meaning your body can fully digest and utilize all 28 grams of protein for muscle synthesis, recovery, and overall health.

Both. The high protein content (28g) supports muscle preservation and growth while the low calorie count (150) fits easily into any calorie deficit or maintenance plan. Protein also increases satiety, helping you feel fuller longer.

David delivers 75% of its calories from protein—roughly 50% more than typical protein bars. Most competitors offer 20g protein at 300+ calories. David gives you 28g at only 150 calories with zero sugar, making it the most efficient portable protein available.

Most athletes report no digestive issues. However, David contains maltitol (a sugar alcohol) and EPG (modified plant fat), which some people may be sensitive to. Start with one bar to assess your tolerance.
