L-Citrulline 500mg 60c by Source Naturals – Nitric Oxide Support Amino Acid
L-Citrulline 500 mg capsules by Source Naturals provide a free-form amino acid in a 60-capsule bottle. This single-ingredient formula supplies L-citrulline rather than citrulline malate, with 2 g in each four-capsule serving. It offers a focused option for adults considering amino acid supplementation as part of an active lifestyle, without combining several sports nutrients in one formula.
Citrulline participates in the body's handling of nitrogen and serves as a building block for arginine. Understanding those roles helps distinguish everyday nutritional support from promises of a faster workout or a guaranteed change in performance.
Key L-Citrulline 500mg 60c Benefits
- Provides a precursor for arginine, helping supply the amino acid the body uses for normal nitric oxide production and communication between blood vessels and surrounding smooth muscle.
- Supports normal nitrogen metabolism through citrulline's participation in the urea cycle, the pathway that packages nitrogen waste for elimination.
- Complements an active lifestyle with targeted support for these normal physiological processes, rather than a multi-ingredient sports blend.
How L-Citrulline 500mg 60c Works
After absorption, citrulline can travel to the kidneys, where it is converted into L-arginine. The body uses arginine to make nitric oxide, a short-lived messenger involved in normal blood-vessel relaxation. This is why citrulline appears in supplements intended for nitric oxide support and healthy circulation. Citrulline itself is not nitric oxide, and taking it does not guarantee a particular exercise result.
A separate role involves the urea cycle. As the body processes amino acids, it must manage the nitrogen they contain. Citrulline is one intermediate in the sequence that converts ammonia into urea, which is then eliminated in urine. This describes normal nitrogen metabolism, not a general-purpose cleanse.
Key Functional Ingredients Include:
- L-Citrulline: Supplies a precursor for arginine and helps support the body's normal nitric oxide pathway. Nitric oxide signals the smooth muscle around blood vessels to relax, contributing to normal vascular function. Citrulline also participates in nitrogen processing, connecting this amino acid to both circulation and everyday metabolic activity.
L-Citrulline 500mg 60c Is Formulated For
- Adults seeking a free-form L-citrulline supplement rather than a citrulline-malate combination.
- Active adults who want to understand and support normal amino acid and nitrogen pathways alongside adequate nutrition.
- People comfortable taking capsules in the divided schedule specified below. The gelatin capsule makes this formula unsuitable for vegetarian or vegan preferences.

Frequently Asked Questions About L-Citrulline 500mg 60c
What are the benefits of L-Citrulline 500mg 60c?
This Source Naturals formula supplies citrulline, which the body can convert to arginine for normal nitric oxide production. That pathway contributes to the signaling involved in healthy blood-vessel relaxation. Citrulline also participates in the urea cycle, helping the body process nitrogen waste from amino acid metabolism. Each four-capsule serving provides 2 g of L-citrulline. These are nutritional and physiological roles, not a promise of greater strength, faster recovery, or a particular athletic result.
Who should take L-Citrulline 500mg 60c?
Adults seeking a focused citrulline supplement can consider this formula with their healthcare professional, particularly when comparing single-ingredient capsules with combination sports supplements. It contains L-citrulline rather than citrulline malate and uses gelatin capsules, so it is not a vegetarian or vegan choice. The suggested use is four capsules three times daily, which is important to consider if swallowing several capsules is difficult. Pregnancy, breastfeeding, prescription medication use, and a history of heart attack require attention to the warnings below.
Are there any side effects of taking L-Citrulline 500mg 60c?
Citrulline can cause an upset stomach. Consult your physician prior to using this product if you are pregnant, may become pregnant, breastfeeding, or if you are taking prescription medications for conditions such as heart disease or erectile dysfunction. Not recommended for use following a heart attack. Also discuss blood pressure or blood vessel concerns and kidney or liver problems with your clinician. Blood pressure medicines, nitrates, and erectile dysfunction medicines need pharmacist review because interactions are not fully understood. Do not use if either tamper-evident seal is broken or missing. Keep out of the reach of children.
How does L-Citrulline 500mg 60c support overall health?
Citrulline connects two normal processes: supplying arginine for nitric oxide signaling and participating in the handling of nitrogen waste. Nitric oxide helps blood vessels communicate with surrounding smooth muscle, while the urea cycle helps package nitrogen for elimination. Source Naturals provides this amino acid in free-form capsules without adding a second active ingredient. That makes the formula targeted rather than comprehensive: it does not supply complete protein, replace meals, or take the place of a balanced exercise and nutrition routine.
