Natural Factors L-Arginine offers a solid 1000mg dose per capsule at a fair price, supported by strong customer reviews, making it a reliable choice for general L-Arginine supplementation.
Quantity: 180
This Natural Factors L-Arginine product technically provides 1000mg of L-Arginine Hydrochloride per capsule, which is a favorable aspect for convenience, despite its misleading name '500 mg'. L-Arginine is a vital amino acid known for its role as a precursor to nitric oxide (NO), crucial for vasodilation and improved blood flow, directly supporting cardiovascular health, muscle nutrient delivery, and potentially muscle gain during intense exercise. While a 1000mg dose is a good starting point, many nutritionists and fitness professionals recommend higher daily dosages, often between 3g to 6g, to achieve significant physiological effects, meaning multiple capsules would be needed daily. The price per serving of $0.21 for 1000mg is reasonable but not the most competitive in the market, as several alternatives offer similar or higher concentrations at a lower per-milligram cost. The product boasts a high number of positive reviews online, indicating widespread customer satisfaction and trust in the brand.
- Provides 1000mg of L-Arginine HCl per capsule, a good dose for convenience.
- High review count indicates good customer satisfaction and product reliability.
- Natural Factors is a reputable brand known for quality supplements.
- The product name '500mg' is misleading, as the ingredient list specifies 1000mg L-Arginine Hydrochloride.
- Price per serving is higher compared to some top value alternatives for pure L-Arginine, making it less cost-effective per milligram.
- Consult a healthcare professional before use if you are pregnant, nursing, have a medical condition (especially cardiovascular issues or herpes), or are taking medications.

Goals
Fitness 75.0
L-Arginine supports exercise performance and recovery by improving blood flow, though higher daily doses (3-6g) are typically recommended to see significant benefits, requiring multiple capsules to achieve optimal athletic support.
Cardiovascular Support 75.0
As a precursor to nitric oxide, L-Arginine helps relax blood vessels, which can contribute to healthy blood pressure and circulation, benefiting cardiovascular health, though higher therapeutic doses are often studied for more pronounced effects in this area.
Muscle Gain 70.0
Improved blood flow can enhance nutrient delivery to muscles, indirectly supporting muscle gain, but L-Arginine is not a direct muscle builder, and its impact is often synergistic with other compounds and proper training for significant effects.
