THORNE L-Arginine Sustained Release is a 24-hour arginine capsule formula designed to help maintain steady arginine levels that support healthy circulation and exercise recovery when used as directed.

THORNE’s L-Arginine Sustained Release delivers a pure arginine amino acid in a capsule engineered to release gradually, helping to sustain blood levels across the day when taken as recommended.

It’s intended for adults seeking nutritional support for vascular function, collagen synthesis, and athletic performance as part of a healthy lifestyle.

How does this sustained-release arginine differ from regular arginine?

Sustained-release capsules release arginine more gradually than immediate-release forms, which can cause a rapid peak and fall in blood levels. This approach aims to provide more consistent availability of arginine throughout the day, reducing the need for frequent dosing and smoothing out amino acid supply.

• Timed-release delivery to maintain arginine levels longer
• Designed for twice-daily use to support 24-hour coverage
• Fewer dosing moments compared with multiple immediate-release capsules

What benefits might I notice during exercise and recovery?

Arginine is an amino acid that plays roles in muscle metabolism and cellular repair processes. Using a sustained-source supplement may support muscle output during workouts and help the body’s natural recovery mechanisms following exertion when combined with proper training and nutrition.

• Support for muscle capacity and workout performance
• Helps supply substrate for post-exercise cellular repair
• Convenient dosing fits into pre- and post-workout routines

Is this product safe and independently verified?

THORNE L-Arginine Sustained Release is third-party certified, meaning an independent lab has tested the product to confirm the label contents and screen for common contaminants. Third-party verification adds a layer of quality assurance beyond in-house testing.

• Third-party tested for ingredient accuracy and purity
• Manufactured by a brand trusted by professional sports teams and clinicians
• Clear labeling for dose and serving information

How should I take THORNE L-Arginine for best results?

For sustained coverage, take the product as the label directs—typically twice daily—to support steady arginine availability. Pair it with a balanced diet and adequate hydration; consult a healthcare professional before use if you have medical conditions or take medications.

• Follow label directions for twice-daily dosing to maintain 24-hour levels
• Take with water and consider timing around meals or workouts per personal routine
• Consult your clinician if pregnant, nursing, or managing health conditions

Who is this for? THORNE L-Arginine Sustained Release is aimed at adults seeking a reliable source of arginine to complement cardiovascular and exercise-supporting routines.
