Muscle Code Essential Amino Acid Capsules – Muscle Synthesis & Repair & Strength

Your muscles are constantly breaking down and rebuilding. To support this process, your body depends on essential amino acids (EAAs)—the building blocks of protein—nutrients your body cannot produce on its own. Adequate amounts and balance of EAAs are necessary to maintain efficient protein synthesis. That’s why Muscle Code by Nautilus was developed: a patented, clinically studied formula delivering EAAs in the precise balance your body needs. Unlike incomplete protein sources (beans) or generic BCAA blends, Muscle Code delivers the full spectrum of essential amino acids to support muscle protein synthesis. Leucine, a key trigger for initiating this process, works in balance with isoleucine, valine, lysine, and others. Designed for efficient amino acid utilization, Muscle Code helps support muscle protein synthesis and recovery. Amino acids are the building blocks of protein, found in your muscles, organs, skin, and more. Essential amino acids (EAAs) can’t be made by the body, so they must come from diet or supplements. Muscle Code provides EAAs to help support muscle protein synthesis and post-exercise recovery. Brought to you by Nautilus, a world-class fitness brand trusted for decades, 20 years of research, and recommended by Dr. Smith L. Johnston, former Chief Medical Officer for NASA, Muscle Code is a rapidly absorbed source of essential amino acids. It’s designed for efficient use by the body—supporting muscle protein synthesis, post-exercise recovery, and overall training nutrition. Fuel your muscles with the code they understand. Fuel them with Muscle Code by Nautilus. Disclaimer: *Based on an acute 3-hour study in healthy adults measuring muscle protein synthesis after 3.6 g EAAs vs published data on 40 g whey isolate; model-based per-gram estimate of product consumed.

• WHAT ARE ESSENTIAL AMINO ACIDS? – Your body can't produce the 9 essential amino acids on its own, meaning they must come from food or supplementation. Muscle Code delivers all 9 EAAs plus arginine in precise ratios designed to help support muscle protein synthesis and recovery.
• YOUR BODY CAN'T MAKE ESSENTIAL AMINO ACIDS – Essential amino acids must come from your diet. Muscle Code delivers all 9 EAAs plus arginine in a patented formula designed to help support muscle protein synthesis, recovery, and lean muscle maintenance.
• BACKED BY DECADES OF RESEARCH – Developed by Dr. Robert Wolfe, a pioneer in amino acid science, with research supported by NASA and the NIH. Built on decades of clinical research to deliver essential amino acids in scientifically studied ratios.
• FAST ABSORPTION, NO HEAVY PROTEIN SHAKES – Unlike traditional protein powders that require digestion, Muscle Code's essential amino acids are rapidly absorbed to help support muscle protein synthesis without the heaviness, lactose, or extra calories.
• CLEAN DAILY NUTRITION FOR ACTIVE LIFESTYLES – Vegan, non-GMO, gluten-free, and easy to take. Whether you're working out, staying active, or supporting healthy aging, Muscle Code helps provide the essential building blocks your muscles need.
