Great Value L‑Arginine for Energy, Circulation & Exercise Support

I’ve been taking Now Foods Sports Double Strength L-Arginine 1000 mg since starting my workout-focused supplement routine. I usually take one tablet around 30 minutes before my morning workout, and another if I’m doing a second session or a long day. The bottle has 180 tablets, which is a great size—compact, portable, and it lasts a long time. This is a mid-range product that offers amazing value for what you get. Each tablet contains 1000 mg of pure L-Arginine without any fancy extras or flavors, and it’s free from gluten, soy, and dairy. It’s made in a GMP-certified facility, which gives me confidence in its quality. There are no unnecessary fillers, just the clean ingredient I’m looking for. Since adding it to my routine (along with NAC, biotin, citrulline, and Duphaston), I’ve noticed better blood flow during workouts, less fatigue in my legs, and a smoother pump during strength training—my muscles feel more energized and recover faster. On rest days, I feel more alert and focused, likely thanks to the improved circulation. It even seems to help with circulation support for mild swelling on busier days. All in all, this L‑Arginine from NOW is a solid, dependable pick—clean, effective, and budget-friendly. It fits seamlessly into my PCOS-friendly, fitness-oriented supplement regimen, and I’ll definitely reorder it.
