Short answer: L-Citrulline's conversion to L-Arginine supports more consistent availability across the day — a specific, named advantage over a single-source amino acid approach.
Why "sustained-release logic" is listed among the formula's ten advantages
This reflects a genuine pharmacological rationale — L-Citrulline's delayed conversion timeline extends nitric oxide support beyond what L-Arginine alone would provide.
Why this connects directly to the formula's "reduced circulatory strain" claim
Smoother blood flow through relaxed vessels can help ease the workload on the cardiovascular system during daily activity — the downstream benefit this sustained-release mechanism is designed to support.
💡 Worth knowing: this is one of six supporting roles the formula's "How It Works" section is built around.
