Jarrow Formulas Arginine-Citrulline Sustain – Dual Action Nitric Oxide Support
Jarrow Formulas Arginine-Citrulline Sustain is a scientifically designed formula that combines two powerful amino acids — L-Arginine and L-Citrulline — along with Vitamin C (as calcium ascorbate), in a sustained-release delivery system. This advanced blend supports optimal nitric oxide (NO) production, healthy blood flow, cardiovascular function, and athletic performance.
Key Benefits:
Enhanced Nitric Oxide Production – Dual Pathway Support
L-Arginine is a direct precursor to nitric oxide, which helps relax and dilate blood vessels for improved blood flow.
L-Citrulline converts into L-Arginine in the body and prolongs its effect, helping to sustain nitric oxide levels longer.
The combination is more effective than arginine alone in boosting NO availability.
Cardiovascular & Circulatory Health
Promotes healthy blood pressure, improved vascular tone, and arterial flexibility.
Supports heart health by enhancing endothelial (blood vessel lining) function.
Exercise Endurance & Recovery
Improved circulation enhances oxygen and nutrient delivery to muscles, supporting greater stamina and endurance.
Helps reduce fatigue and supports faster recovery post-exercise, making it ideal for active lifestyles and athletes.
Immune & Antioxidant Support (Vitamin C)
Vitamin C (as calcium ascorbate) provides antioxidant protection, supporting immune function and protecting cells from oxidative stress.
Also helps maintain collagen synthesis and vascular integrity.
Supports Detoxification and Urea Cycle
L-Citrulline plays a key role in the urea cycle, helping the body eliminate ammonia, a waste product from protein metabolism.
This supports metabolic health and detoxification pathways.
Sustain Release Technology – Longer Lasting Benefits
This formulation uses Sustain™ time-release delivery, designed to optimize absorption over time.
It provides a gradual release of L-Arginine and L-Citrulline, promoting steady nitric oxide production without sharp peaks and drops.
Additional Ingredients for Tablet Stability & Quality:
Bulking Agent: Cellulose
Anti-Caking Agents: Silicon Dioxide, Magnesium Stearate (vegetable source)
Food-grade coating (cellulose, vegetable-based stearic acid) ensures tablet integrity and ease of swallowing.
Who Might Benefit From Arginine-Citrulline Sustain:
Individuals seeking to support cardiovascular wellness and circulation
Those with low energy or poor endurance
Athletes and fitness enthusiasts aiming for enhanced performance and recovery
People looking to support blood vessel health, muscle function, and immune resilience
