Time Release Protein

NRG Fuel Casein Protein is an effective time release protein delivery system that helps to ensure optimal nutritional support that helps to prevent muscle breakdown.

Take NRG Casein Protein before sleep as it slowly and steadily releases amino acids whilst resting which is important for muscle recovery, repair and growth.

The total release of amino acids in the blood stream can last up to seven hours with just one serving of NRG Fuel's Casein Protein.
