Overview

THORNE L-Arginine Sustained Release (formerly Perfusia-SR) combines a trusted brand with a smart delivery system designed to support arginine levels across the day. The formulation is optimized to work with your routine, helping you move through activities with steadier arginine presence rather than quick spikes. While results vary by individual, many users notice a sense of steadier energy and vascular comfort during daily tasks and workouts.

How it works

This sustained-release formula aims to maintain arginine levels over 24 hours when taken twice daily, reducing the peaks and troughs that immediate-release options can create. The approach centers on consistent availability, which may influence how you feel during activities that rely on normal blood flow and nutrient delivery.

Key benefits

Usage and considerations
