Arginine 500mg Citrulline 250mg 120c by Now Foods – Protein Metabolism Amino Acid Support
Arginine Citrulline capsules by Now Foods combine two free-form amino acids in a vegetarian capsule. Each capsule supplies 500 mg of arginine and 250 mg of citrulline, bringing together related nutrients involved in protein metabolism and normal nitrogen handling.
This amino acid supplement contains 120 veg capsules and focuses on a two-ingredient combination rather than a complete protein formula. Free-form means the amino acids are supplied individually, rather than bound together in a dietary protein. That distinction helps you compare this product with protein powders and broader amino acid blends; they serve different nutritional purposes.
Key Arginine 500mg Citrulline 250mg 120c Benefits
- Supplies arginine, a building block the body uses to make proteins needed for everyday tissue maintenance and renewal.
- Pairs arginine with citrulline, which the body can convert into additional arginine through its normal metabolic pathways.
- Provides amino acids involved in the urea cycle, the process that packages excess nitrogen for removal from the body.
How Arginine 500mg Citrulline 250mg 120c Works
Arginine and citrulline participate in connected pathways, but they are not interchangeable. Arginine can become part of proteins used throughout the body, including muscle tissue. Citrulline is not incorporated directly into proteins; instead, it helps supply arginine. These roles explain the formula's emphasis on muscle maintenance without making it a substitute for adequate dietary protein.
The urea cycle handles nitrogen released as amino acids are broken down. It converts ammonia into urea for excretion. Arginine also supplies the raw material for nitric oxide, a short-lived messenger used in normal blood-vessel signaling. This describes normal physiology, not a promise of improved circulation, larger muscles, or better workout performance from these capsules.
Key Functional Ingredients Include:
- L-Arginine: Supports normal protein synthesis by supplying an amino acid that cells use to assemble proteins. It also contributes to the urea cycle and serves as a precursor to nitric oxide, connecting protein metabolism with the body's everyday nitrogen processing and cell signaling.
- L-Citrulline: Helps replenish the body's arginine supply through conversion to arginine, particularly in the kidneys. This provides an indirect connection to nitric oxide production. Citrulline also participates in the urea cycle, complementing arginine's role in normal amino acid metabolism rather than acting as a complete dietary protein.
Arginine 500mg Citrulline 250mg 120c Is Formulated For
- Adults seeking a defined arginine-and-citrulline combination in veg capsules, with clearly stated amounts for each amino acid.
- Adults comparing targeted amino acid supplementation with their existing protein intake and practitioner-guided wellness routine.

Frequently Asked Questions About Arginine 500mg Citrulline 250mg 120c
What are the benefits of Arginine 500mg Citrulline 250mg 120c?
This Now Foods formula supplies two amino acids involved in normal protein and nitrogen metabolism. Arginine helps the body build proteins, while citrulline can be converted into arginine. Both participate in the urea cycle, which helps process nitrogen from amino acid breakdown. Each veg capsule provides 500 mg of arginine and 250 mg of citrulline. These nutritional roles explain the formula's purpose; they do not mean taking it guarantees muscle growth or improved exercise performance.
Who should take Arginine 500mg Citrulline 250mg 120c?
The label specifies adults only. This product suits adults considering a targeted combination of free-form arginine and citrulline rather than a full protein supplement. Its veg capsule format is relevant when comparing capsule ingredients and dietary preferences. The manufacturer directs one capsule twice daily. If you are pregnant or nursing, take medication, or have a medical condition, consult your physician first, particularly with the heart medications and conditions identified in the warnings.
Are there any side effects of taking Arginine 500mg Citrulline 250mg 120c?
Possible effects include nausea, stomach pain, diarrhea, bloating, gout, headache, allergy, or worsened asthma. Adults only; keep away from children. Consult a physician if pregnant/nursing, using medication, especially antihypertensives, nitrates, or heart medicines, or managing herpes, kidney impairment, glaucoma, or another condition. Avoid after a recent heart attack and with potassium-sparing diuretics. Blood thinners, diabetes medicines, and sildenafil also require review. The label excludes wheat, gluten, soy, milk, egg, fish, shellfish, tree nut and sesame ingredients, but the facility processes these allergens. Medication combinations can increase bleeding, low blood pressure, low blood sugar, or high-potassium risks.
How does Arginine 500mg Citrulline 250mg 120c support overall health?
The formula supplies amino acids used in connected metabolic pathways. Arginine contributes to protein synthesis and is a precursor to nitric oxide, a messenger involved in normal blood-vessel signaling. Citrulline helps supply arginine and participates in nitrogen processing through the urea cycle. This is a focused supplement, not a complete source of protein or all essential amino acids. Assess it alongside your food intake and medications rather than assuming more amino acids automatically means greater benefit.
