THORNE L-Arginine Sustained Release 120 Capsules — 24‑Hour Slow‑Release for Circulation & Exercise Recovery

THORNE L-Arginine Sustained Release is a 24-hour, slow-release arginine capsule designed to support healthy circulation, exercise capacity, and cellular repair when taken as directed.

L-Arginine is a naturally occurring amino acid that plays a role in nitric oxide production and vascular tone. Thorne’s sustained-release formulation delivers smaller amounts of arginine over an extended period so blood levels remain steadier across the day. Each bottle contains 120 capsules suitable for a twice-daily regimen to maintain consistent arginine availability without the spikes associated with immediate-release products.

How does sustained-release arginine help throughout the day?

Slow-release L-Arginine releases active ingredient gradually, avoiding large peaks and troughs in blood arginine concentration. That steady availability supports ongoing processes like vascular relaxation and nutrient delivery to tissues. It is intended to be taken twice daily to keep levels consistent for roughly 24 hours.

• Capsules formulated to dissolve over time for prolonged arginine delivery
• Twice-daily dosing recommended to sustain circulating arginine
• Reduces need for frequent dosing compared with immediate-release forms

Can this product support exercise and recovery?

L-Arginine contributes to nitric oxide pathways which can help deliver oxygen and nutrients to working muscles during activity. In combination with proper training and nutrition, it may help support muscle capacity and post-exercise cellular repair. Results depend on overall lifestyle, training load, and individual response.

• Supports nutrient and oxygen transport to muscles during workouts
• May aid cellular repair processes after exertion
• Useful as part of a broader performance and recovery plan
