Formulated to maintain optimal levels of L-arginine over 24 hours.
L-arginine is a conditionally essential amino acid vital for various bodily functions. It is a fundamental building block of protein that supports muscle and tissue repair, boosts immune system health, and aids in cellular metabolism. Crucially, L-arginine is necessary for the production of nitric oxide, a key signalling molecule involved in regulating blood flow, mitochondrial function, and cellular communication. Nitric oxide helps maintain healthy blood pressure, improves vascular elasticity, and optimises blood flow to various parts of the body.
Supplementing with L-arginine is important when natural production may be compromised by intense physical activity, injury recovery, or specific health conditions.
This advanced supplement combines L-arginine with Thorne's Time-Sorb® complex to help maintain optimal levels of this amino acid over 24 hours with suggested use. It provides continuous support for regulating blood pressure, promoting healthy cardiovascular function, and promoting blood flow to the extremities. It also aids in wound healing and boosts exercise performance as well as enhances sexual wellness, particularly by supporting the occurrence and maintenance of erections during intimacy.
Each serving delivers a potent dose of 1000 mg (1g) of L-arginine in its highly absorbable form, ensuring optimal levels throughout the day to support overall wellbeing and specific health goals.
Thorne’s L-Arginine - Sustained Release features the innovative Time-Sorb® complex, which utilises a blend of hydroxypropyl methylcellulose and magnesium citrate laurate instead of traditional plasticizers, magnesium stearate, and waxes. This advanced formulation protects the active ingredient as it passes through the stomach, allowing for gradual release over an extended period. By maintaining optimal L-arginine levels in the body for over 24 hours, this sustained-release formula maximises the supplement’s efficacy, providing continuous support throughout the day.
Thorne sets the standard for excellence in the supplement industry. Recommended by over 100 professional sports teams and U.S. National Teams, Thorne offers a curated bundle of clean, science-backed supplements and treats designed to fuel your body naturally and effectively. With more than 30 years of dedication to quality, Thorne's commitment to purity and potency begins with sustainably sourced ingredients and rigorous testing.
