L-Arginine L-Citrulline 1000mg Tablets
DUOZI
Extreme Energy & Intensity · Strength, Power & Endurance · Premium Formula · 90 Tablets
As a leading manufacturer and trusted supplier of premium sports nutrition supplements, we present DUOZI L-Arginine L-Citrulline 1000mg Tablets – a high‑potency, dual‑action formula designed to support energy, strength, power, and endurance. This advanced blend combines L-Arginine and L-Citrulline – two amino acids that work synergistically to boost nitric oxide production, enhance blood flow, and improve exercise performance. L-Arginine is a direct precursor to nitric oxide, while L-Citrulline is converted to L-Arginine in the kidneys, prolonging the effects and reducing breakdown. Together, they support vasodilation, nutrient delivery to muscles, and efficient removal of waste products – helping you train harder, recover faster, and achieve new performance goals. With 90 tablets per bottle, it provides a convenient 45‑day supply at the recommended dose of 2 tablets daily – the ideal choice for athletes, bodybuilders, and fitness enthusiasts seeking extreme energy and intensity.
L-Arginine and L-Citrulline work together to increase nitric oxide levels – promoting vasodilation, enhancing blood flow, and improving oxygen and nutrient delivery to working muscles. This leads to better pumps, increased vascularity, and enhanced performance.
By improving circulation and nutrient delivery, this formula helps you train with more intensity and for longer periods. It supports ATP production, reduces fatigue, and helps you push through plateaus – giving you the edge you need to reach your goals.
Enhanced blood flow creates a more pronounced muscle pump during training, while improved nutrient delivery and waste removal support faster recovery between sets and sessions.
Beyond performance, L-Arginine and L-Citrulline support cardiovascular function by promoting healthy blood vessel dilation and maintaining healthy blood pressure levels already within the normal range. They also support immune function and overall wellness.
Each serving delivers a potent 1000mg of L-Arginine and L-Citrulline – a clinically relevant dose for performance support. With 90 tablets per bottle, it offers excellent value for consistent daily use.
