Eating a protein bar before bed is fine and may even help muscle recovery overnight. Casein protein is ideal for nighttime since it digests slowly (6-8 hours). Avoid bars with caffeine or high sugar that could disrupt sleep.

Research shows that consuming 20-40g of protein before bed can increase overnight muscle protein synthesis by up to 22%. Casein protein is ideal because it digests slowly, providing a steady stream of amino acids while you sleep. However, eating too close to bedtime can cause acid reflux in some people, and high-sugar bars may disrupt sleep quality. The best approach: eat a moderate-protein bar 30-60 minutes before bed.
