This supplement combines two well-known free-form amino acids — L-Arginine and L-Citrulline — in a single, easy-to-take capsule. Packaged by Nutricost in a GMP-compliant, FDA-registered facility, the product is third-party tested, non-GMO and gluten-free. The 240-capsule supply is intended to give you a cost-effective way to include these amino acids in a daily routine.
The capsules are formulated for simple dosing: each contains 750mg of combined L-Arginine and L-Citrulline in free-form, which dissolves quickly for reliable absorption. Because they are single-ingredient amino acids with minimal excipients, they pair well with other vitamins or fitness supplements.
Nutricost emphasizes quality control: the capsules are produced in a GMP-compliant, FDA-registered facility and undergo third-party testing. The product is labeled gluten-free and non-GMO, reducing the risk of unwanted additives or common allergens.
Follow the dosage instructions on the bottle and consult a healthcare professional if you have medical conditions or take prescription medication. Start with the manufacturer’s recommended serving to observe tolerance, then adjust as advised by your practitioner.
A 240-count bottle is designed for regular users seeking value and fewer reorder cycles. The size is also travel-friendly when portioned into morning and evening supply containers.
Who is this for? This Nutricost formula is aimed at adults who want an uncomplicated, third-party-tested source of L-Arginine and L-Citrulline in free-form capsules. It suits people seeking a gluten-free, non-GMO option produced in a GMP-compliant facility, especially those who prefer capsules over powders and value a larger 240-count bottle for long-term use. Avoid use if you have specific medical conditions or are under a physician’s care without prior approval.
