Leucine

Leucine plays a crucial role in muscle protein synthesis and can be particularly significant for those following a plant-based diet or looking to optimize their fitness and wellness. Here are some insights based on what Andrew Huberman has discussed:

1. Muscle Protein Synthesis: Leucine is a key driver of muscle protein synthesis. Adding free leucine to plant-based proteins to match the content found in whey can produce identical protein synthesis responses, making it crucial for muscle building, especially for those not consuming animal products 1.

2. Dosage and Sources: For muscle support, it's recommended to ingest 700 to 3000 milligrams of leucine per meal, which can be obtained from both food sources and supplements. The form of leucine and its compatibility with one's diet (vegan or otherwise) should be considered 2.

3. Health and Longevity Implications: While leucine is beneficial for muscle growth and recovery, its impact on the Mtor pathway also suggests it could promote cellular growth, which might have implications for aging. This aspect requires careful consideration, especially for those focused on longevity 3.
