SUPPLI-X Nitric Oxide | L-Citrulline, L-Arginine & AAKG | 60 Capsules

More Blood Flow. Bigger Pump. Better Performance.

Nitric oxide is the molecule behind the pump — the vasodilation that drives blood, oxygen, and nutrients into working muscles during training. SUPPLI-X Nitric Oxide is a precision amino acid formula built around a triple-source NO precursor stack: L-Citrulline DL-Malate, L-Arginine Hydrochloride, and L-Arginine Alpha-Ketoglutarate (AAKG) — each targeting nitric oxide production through complementary pathways for sustained vascular support before, during, and after training.*

Why Three Forms of NO Precursors

L-Arginine is the direct precursor to nitric oxide, but its oral bioavailability is limited when taken alone. L-Citrulline solves this — it converts to L-Arginine in the kidneys with significantly higher efficiency, sustaining plasma arginine levels longer than arginine supplementation alone. AAKG (Arginine Alpha-Ketoglutarate) adds a third angle, supporting both nitric oxide synthesis and cellular energy metabolism via the Krebs cycle. Together, the three forms create a more complete and sustained NO response than any single ingredient can deliver.

What You Get

• L-Citrulline DL-Malate (400 mg) — the most bioavailable NO precursor; converts to arginine in the kidneys for sustained nitric oxide production and reduced muscle fatigue
• L-Arginine Hydrochloride (350 mg) — direct nitric oxide precursor; supports vasodilation, blood flow, and nutrient delivery to muscles
• L-Arginine Alpha-Ketoglutarate / AAKG (50 mg) — supports NO synthesis and cellular energy metabolism via the Krebs cycle
• Vegetable cellulose capsule — no gelatin, suitable for vegetarians
• 60 capsules — 30-day supply | Made in the USA in a GMP-certified facility

Pair It With

Stack with SUPPLI-X Nitric Shock Pre-Workout Booster for a complete pre-training pump and energy stack — combining NO precursors with stimulants, beta-alanine, and performance-focused ingredients for maximum output.

How to Use

Take two (2) capsules daily with 6-8 oz of water, or as directed by a healthcare professional. For best results, take 30-45 minutes before training.
