Asahi, a trusted name in Japan since 1949, saw a problem: people were struggling to maintain muscle as life got busier. They created Dear-Natura Active Whey + Casein Protein to solve this. Their team of nutritionists in Tokyo spent 3 years developing a dual-protein formula, selecting only the highest-grade whey and casein from Japanese-certified dairies. Every batch is made in a GMP-certified facility and tested 11 times for purity. This commitment to quality is why it's earned the Japanese government's "Foods with Function Claims" designation and has been the top-ranked sustained-release protein in its category for 4 consecutive years. It's not just a supplement; it's a Japanese-engineered solution for modern life.

Asahi Dear-Natura Active Whey + Casein Protein - Sustained Muscle Support contains a blend of high-quality protein sources, primarily whey protein concentrate and casein protein, which are included to provide both rapid and sustained amino acid delivery for muscle recovery and growth. Whey protein is quickly absorbed, offering an immediate supply of essential amino acids to stimulate muscle protein synthesis post-exercise, while casein forms a gel-like substance in the stomach, leading to a slower digestion rate that provides a prolonged release of amino acids over several hours, helping to prevent muscle breakdown during periods of fasting such as sleep. This product also includes soy protein isolate, which adds a plant-based protein component to enhance the amino acid profile and support muscle maintenance. Additionally, it contains digestive enzymes like protease and amylase to improve protein absorption and reduce gastrointestinal discomfort, as well as calcium caseinate to further extend the sustained release effect. The inclusion of branched-chain amino acids (BCAAs)—leucine, isoleucine, and valine—directly supports muscle protein synthesis and reduces exercise-induced fatigue. Sweeteners such as sucralose and acesulfame potassium are used for palatability without adding significant calories, while emulsifiers like soy lecithin ensure smooth mixing. Collectively, these ingredients work synergistically to offer comprehensive muscle support, promoting efficient recovery, reducing catabolism, and supporting lean muscle mass development, making it suitable for athletes and active individuals seeking sustained nutritional benefits throughout the day.
