Product Overview

Casein is naturally rich in amino acids like leucine and glutamine. Because of its slow-release nature, casein provides a steady stream of these amino acids to support muscle growth and recovery over several hours.* All of this makes casein the perfect nighttime protein! Enjoy it as a shake or pudding an hour before bedtime or during long stretches between meals.
CASEIN VS. WHEY
Building muscle isn’t just about consuming enough protein: It has to be the right protein. Whey protein digests quickly and is ideal for stimulating muscle protein synthesis after your workout. Casein, on the other hand, digests slowly and inhibits muscle protein breakdown.*
When you ingest whey protein, the amount of amino acids in your bloodstream rapidly peaks, then declines. Ingestion of casein causes a slow and steady increase of amino acids in your blood, supporting muscle recovery over a longer period of time.*
A signature is a promise. A symbol of your identity. Your mark on the world. In 1999, Bodybuilding.com was founded on a single promise: Trust. It’s who we are and it’s in our blood. Our Signature line is built on the same promise. Every product is no-BS, transparent, filler-free, and formulated with effective doses of research-backed ingredients you can trust. We create the highest quality supplements, so you can focus on leaving a mark of your own.
TOTAL TRANSPARENCY
Signature products are formulated with high quality ingredients at effective doses that we’re proud to share with you. We don’t hide anything in a “proprietary blend”, so you always know exactly what you’re putting into your body.
EFFECTIVE DOSES
An effective dose is the amount of an ingredient that has been shown to deliver results. Some supplement brands add a sprinkle of an ingredient just so they can say it’s in the product. Signature supplements always include enough to get the job done.
RESEARCH-BACKED INGREDIENTS
Trendy, flash-in-the-pan ingredients come and go. But time-tested, gym-proven ingredients are what you need to help you achieve your fitness goals. That’s what you’ll find in Signature products because that’s what works.
