L-threonine

What Does L-Threonine Do?

L-Threonine is an essential amino acid that serves as a fundamental building block for protein synthesis, meaning your body cannot produce it and must acquire it through your diet or supplements. In a pre-workout context, it acts as a structural stabilizer, ensuring that the stress of high-intensity training doesn't outpace your body's ability to repair itself.

• Muscle Protein Synthesis: It provides the necessary nitrogen balance required for the body to build and maintain lean muscle mass during and after strenuous exercise.
• Connective Tissue Support: Threonine is a direct precursor to collagen and elastin production, which are vital for maintaining the strength and elasticity of your tendons and ligaments.
• Immune System Defense: It is heavily involved in the production of antibodies and the health of the thymus gland, helping you avoid the 'overtraining' sickness that can derail a program.
• Central Nervous System Function: By supporting the maintenance of the myelin sheath around nerves, it helps ensure efficient signal transmission from your brain to your muscles.

Clinical vs. Gym Bro Dosing

Key Insight: The recommended dosage of 500mg is the 'sweet spot' for most lifters. However, remember that L-Threonine is most effective when it is part of a complete Essential Amino Acid (EAA) matrix, as amino acids work synergistically to trigger the mTOR pathway for muscle growth.

Side Effects & Warnings

• Gastrointestinal Issues: In rare cases, high doses on an empty stomach might lead to mild bloating or nausea.
• Metabolic Processing: As with any amino acid, your body must process it through the liver and kidneys; while safe for healthy individuals, those with pre-existing conditions should consult a doctor.

Tip: To maximize the absorption of L-Threonine, ensure you are staying hydrated. Because it is a water-soluble amino acid, your body utilizes it most efficiently when your cellular hydration levels are optimal.
