ON Gold Standard 100% Casein

Gold Standard 100% Casein Protein

Slow-Digesting Casein Protein designed to provide a steady release of amino acids over an extended period. Unlike fast-absorbing proteins, casein forms a gel in the stomach, allowing for a gradual digestion process that helps support muscle recovery and reduce muscle breakdown.

Key Benefits

• 24g Slow-Digesting Casein Protein per serving for extended amino acid delivery
• Rich in Micellar Casein, a premium form of slow-release protein
• Provides over 9g of BCAAs, Glutamine & Glutamine Precursors per scoop
• AMINOGEN Enhanced for improved protein utilization
• Supports muscle recovery, growth, and anti-catabolic benefits

Why Choose Casein Protein?

Sometimes slower is better. Casein protein is naturally digested more slowly than whey and other protein sources, creating a sustained release of amino acids to your muscles over several hours.

This unique "timed-release" effect helps maintain a positive nitrogen balance and creates a muscle-friendly environment by supporting recovery and helping reduce muscle breakdown. Casein is an excellent choice for athletes, bodybuilders, and anyone looking to support lean muscle development.

Supports Overnight Recovery

Due to its slow digestion rate, casein protein is commonly used before bedtime to provide your muscles with a continuous supply of amino acids while you rest. It can also be used between meals or anytime delayed protein absorption is desired.

Research-Backed Benefits

Scientific research has shown that casein protein can help support muscle protein balance by increasing protein synthesis while reducing protein breakdown. Studies comparing casein-based proteins with faster-digesting proteins have demonstrated benefits for improving body composition, lean muscle gains, and strength during resistance training.

Beyond The Basics

• 24g instantized blend of slow-digesting casein-based proteins
• High-quality micellar casein formula
• Over 9g of BCAAs, glutamine, and glutamine precursors per scoop
• Enhanced with AMINOGEN

Suggested Use

Mix as directed and consume first thing in the morning, before bedtime, between meals, or whenever a slow and sustained protein release is desired.

For optimal results, aim to consume approximately 1 gram of protein per pound of body weight per day from a combination of high-protein foods and supplements, spread throughout the day.
