Source Naturals L-Lysine Free Form Powder – Supports Collagen & Energy Metabolism, 100 g

Source Naturals L-Lysine Free Form Powder offers a clean, vegetarian-friendly amino acid option that fits smoothly into a busy day. This free-form powder uses L-lysine, an essential amino acid that participates in multiple protein-related pathways and can serve as a building block for other amino acids.

• Biochemical roles: L-Lysine acts as a precursor for other amino acids such as L-citrulline and L-carnitine, which can support normal metabolic processes.
• Collagen synthesis: L-Lysine is involved in collagen formation, a major component of connective tissues you rely on in daily life.
• Energy metabolism: When converted to acetyl coenzyme A, L-lysine participates in pathways that help fuel cellular energy production in the Krebs cycle.
