L-Arginine – Sustained Release: A Formula for Nitric Oxide and Blood Flow
Thorne’s L-Arginine – Sustained Release, formerly known as Perfusia-SR®, is a high-quality amino acid supplement designed to support cardiovascular health and optimal blood flow. L-arginine is the body’s primary precursor to nitric oxide, a crucial molecule that helps blood vessels relax and dilate. This advanced formula utilizes a proprietary time-release matrix (Time-Sorb®) to release L-arginine gradually, ensuring a sustained benefit for circulation and vascular health throughout the day.
How It Works: The Time-Sorb® Advantage
Standard L-arginine is metabolized very quickly by the body. This formula is designed to provide a more lasting effect.
Promoting Healthy Circulation
The key ingredient, L-Arginine, is converted in the body into nitric oxide. Nitric oxide signals the smooth muscles of the arteries to relax, which promotes healthy circulation and helps to maintain blood pressure already in the normal range. In addition, healthy blood flow is essential for delivering oxygen and nutrients to every part of the body, supporting everything from exercise performance to male reproductive health.
Sustained Release for All-Day Support
The patented Time-Sorb® delivery system complexes the L-arginine with a time-release matrix. This allows it to be released slowly over several hours. As a result, it maintains a more optimal and consistent level in the bloodstream with twice-daily use. This makes it a superior choice for long-term cardiovascular and circulatory support.
