The Science Behind Overnight Recovery

Unlike whey protein that hits your system fast and burns out in 90 minutes, casein forms a gel in your stomach that releases amino acids slowly over 6-8 hours. You get 4.9g of naturally occurring BCAAs and 2.2g of leucine—the key amino acid that tells your muscles to grow, not break down. Research shows that taking 40g of casein protein about 30 minutes before sleep significantly increases amino acid availability during overnight recovery, helping your muscles repair and adapt from your training.
