NOW Foods L-Arginine 500mg (100 Veg Capsules) Nitric Oxide & Cardiovascular Support in Pakistan
NOW Foods L-Arginine 500mg delivers a premium, pharmaceutical-grade free-form L-Arginine — a conditionally essential amino acid and the primary precursor to Nitric Oxide (NO) in the body. Each serving of 2 veg capsules provides 1,000mg (1g) of pure L-Arginine in free-form for maximum absorption and bioavailability. Nitric Oxide is a critical signaling molecule that supports healthy blood vessel dilation (vasodilation), circulation, and cardiovascular function. Under conditions of stress, illness, or intense physical activity, the body's demand for L-Arginine exceeds its natural production capacity — making supplementation especially beneficial for athletes, fitness enthusiasts, and those focused on cardiovascular health. The L-Arginine used in this product is pharmaceutical grade, manufactured and quality tested by NOW Foods — a family-owned brand trusted since 1968. Available at docxora.com — Pakistan's trusted source for authentic imported NOW Foods supplements.
Imagine better blood flow, enhanced exercise performance, impressive muscle pumps, and comprehensive cardiovascular support — all from a single, clean amino acid supplement trusted by athletes and health-conscious individuals worldwide. NOW Foods L-Arginine is your foundation for circulatory health, peak physical performance, and overall vitality.
Key Benefits
Nitric Oxide Precursor — Vasodilation & Blood Flow: L-Arginine is the primary substrate for nitric oxide synthase (NOS) enzymes that produce Nitric Oxide in the body. NO supports healthy vasodilation — the widening of blood vessels — promoting improved blood flow, oxygen delivery, and nutrient transport throughout the body, including to muscles and the heart.
Sports Performance & Muscle Pump: Enhanced nitric oxide production from L-Arginine supplementation supports improved blood flow to working muscles during exercise — promoting better nutrient and oxygen delivery, impressive muscle pumps, enhanced endurance, and improved exercise performance. Ideal for pre-workout use 30-45 minutes before training.
Cardiovascular Health Support: By promoting healthy nitric oxide levels, L-Arginine supports healthy blood pressure regulation, arterial flexibility, endothelial function, and overall heart and circulatory health — making it one of the most researched amino acids for cardiovascular wellness.
Conditionally Essential Amino Acid: Under normal conditions, the body produces L-Arginine from other amino acids. However, during periods of stress, illness, injury, or intense physical activity, demand exceeds production capacity — making dietary or supplemental L-Arginine essential for maintaining optimal levels and supporting recovery.
Protein Synthesis & Muscle Recovery: As a proteinogenic amino acid, L-Arginine participates in protein synthesis and supports muscle tissue repair and recovery after exercise. It also stimulates the release of growth hormone and insulin, further supporting anabolic processes and recovery.
Pharmaceutical Grade — Free-Form for Maximum Absorption: The L-Arginine in this product is pharmaceutical grade and in free-form — meaning it does not require digestion of a protein chain before absorption, allowing for faster and more complete uptake compared to protein-bound amino acids.

Frequently Asked Questions (FAQs)
| ❓ Question | ✅ Answer |
| What is L-Arginine and what does it do? | L-Arginine is a conditionally essential amino acid that serves as the primary precursor to Nitric Oxide (NO) in the body. Nitric Oxide supports healthy vasodilation (blood vessel widening), improved circulation, cardiovascular function, and muscle blood flow during exercise. It also participates in protein synthesis, hormone release, and immune function. |
| What does "pharmaceutical grade" and "free-form" mean? | Pharmaceutical grade means the L-Arginine meets the highest purity standards — free from contaminants and fillers. Free-form means the amino acid is not bound within a protein chain, so it does not require protein digestion before absorption — allowing for faster, more complete uptake by the body compared to protein-bound amino acids. |
| How does L-Arginine support sports performance? | L-Arginine boosts Nitric Oxide production, which causes blood vessels to dilate — increasing blood flow to working muscles during exercise. This delivers more oxygen and nutrients to muscles, resulting in better endurance, impressive muscle pumps, and improved overall exercise performance. Take 30-45 minutes before training for best results. |
| How long does one bottle last? | One bottle contains 100 Veg Capsules providing 50 servings (at 2 capsules per serving). At the recommended dose of 2 capsules per day, one bottle provides a 50-day supply. At 1 capsule per day, it provides a 100-day supply. |
| Can L-Arginine support heart and cardiovascular health? | Yes. By promoting healthy Nitric Oxide levels, L-Arginine supports healthy blood pressure regulation, arterial flexibility, and endothelial function — all key factors in cardiovascular health. However, individuals with cardiovascular conditions or those on blood pressure medications should consult their healthcare provider before use. |
| When is the best time to take L-Arginine? | For general health: take 2 capsules daily on an empty stomach for best absorption. For sports performance: take 30-45 minutes before exercise to maximize nitric oxide production and muscle blood flow during training. You can also split the dose — 1 capsule in the morning and 1 before workout. |
| Is L-Arginine safe for people with heart conditions? | L-Arginine may interact with blood pressure medications and cardiovascular drugs. Individuals with heart conditions, low blood pressure, or those taking cardiovascular medications must consult their healthcare provider before use. Do not use if you have recently had a heart attack without medical supervision. |
| Is this product suitable for vegans? | Yes. NOW Foods L-Arginine uses 100% plant-based hypromellose veg capsules with vegetable-source stearic acid — completely vegan and vegetarian friendly. No animal-derived ingredients are used in this product. |
