4 Key Muscle Building Nutrients: Leucine, Lysine, Glycine & Phosphorous 1. Why Leucine? Leucine activates muscle protein synthesis (MPS), signals that the body has enough EAA’s to build muscle, and inhibits the breakdown of muscle. 2. Why Lysine? Lysine is an essential amino acid for protein synthesis, which is necessary for muscle repair and growth. It also helps produce carnitine, a compound that converts fatty acids into energy for muscle function The Science: 2021 Study: Ingestion of an ampl

Leucine, a key amino acid, is the switch that jumpstarts muscle building—and exercise lowers the amount needed to unlock its benefits ~2-3g of leucine is required to stimulate muscle protein synthesis (known as the leucine threshold) That can be obtained in ~20g of whey protein But here's what's cool... Exercise lowers the leucine threshold (it makes muscle more sensitive to amino acids) That means a lower dose of leucine (and protein) is needed to stimulate muscle protein synthesis __ Find out

The leucine threshold myth is where a lot of people get stuck. Grazing and snacking all day might feel productive, but it’s not doing what you think it is for muscle growth. Muscle protein synthesis doesn’t turn on with tiny hits of protein. It requires a threshold, of at least 30g of protein per meal Snacks here and there don’t add up the same way. Your body needs a clear signal, not constant noise. This is why meal structure matters. Not restriction. Not perfection. Just understanding how your

Protein, Leucine & mTOR: Balance for Longevity 🧬💪 mTOR is a master growth switch. Leucine-rich protein (and insulin) turns it on—great for muscle, recovery, and metabolic health. Turning it down at times—via fasting, lower protein windows, polyphenols, or exercise-induced AMPK—supports cellular repair, autophagy, and lifespan (seen across multiple model organisms). The playbook isn’t “always on” or “always off.” It’s strategic cycling: • Hit a leucine threshold (~2–3 g) with 30–50 g high-quali

Leucine as a Signal for Protein Synthesis and Prevention of Sarcopenia. Leucine, an essential branched-chain amino acid, plays a crucial role in regulating muscle protein synthesis through the activation of the mammalian target of rapamycin (mTOR) signaling pathway.

When it comes to muscle health, it’s not just about how much protein you eat—it’s about how efficiently you hit the leucine threshold to trigger muscle growth. Animal-based proteins (like whey, eggs, beef) hit that 2.5g leucine threshold in just 30–50g of protein, and often for under 200 calories. Now compare that to six cups of quinoa or hundreds of calories of chickpeas and soy just to do the same job. As we age, our muscles become less responsive to protein. That’s called anabolic resistance,
