Arginine-Citrulline Sustain 120t by Jarrow Formulas – Nitric Oxide Support Tablets
Arginine-Citrulline Sustain tablets by Jarrow Formulas combine equal amounts of arginine and citrulline with vitamin C in a sustained-release formula. This 120-tablet bottle provides a focused option for adults seeking nitric oxide support rather than a broad multivitamin or protein powder.
Each two-tablet serving supplies 500 mg of each amino acid and 10 mg of vitamin C. These complementary ingredients have different nutritional roles: arginine provides material for nitric oxide production, citrulline supplies an arginine precursor, and vitamin C contributes antioxidant activity.
Key Arginine-Citrulline Sustain 120t Benefits
- Supports normal nitric oxide production by providing arginine alongside citrulline, which the body converts into additional arginine for its metabolic needs.
- Supports cardiovascular health through nutrients involved in the normal signaling that helps blood vessels relax and regulate blood flow.
- Provides vitamin C for antioxidant support and normal collagen formation, complementing the amino acids with a distinct nutritional function.
How Arginine-Citrulline Sustain 120t Works
Nitric oxide is a short-lived messenger made by cells, including those lining blood vessels. It signals surrounding muscle to relax, helping vessels adjust their diameter as the body's needs change. Arginine is one of the starting materials for this process. Citrulline takes a different route: the body converts it into arginine, linking the two amino acids within the same pathway.
The sustained-release amino acids distinguish this tablet formula from a simple amino acid powder. Sustained release describes the delivery format, not a guarantee of longer-lasting effects or improved exercise performance.
Key Functional Ingredients Include:
- L-Arginine (Free Base): Supplies a building block for nitric oxide, the messenger involved in normal blood-vessel relaxation. Arginine also participates in protein production and nitrogen handling, so its nutritional role extends beyond circulation. This formula pairs it with a precursor rather than relying on arginine alone.
- L-Citrulline (Free Base): Supports the body's arginine supply through conversion that occurs largely in the kidneys. This indirect contribution explains why citrulline complements arginine in a nitric oxide formula, even though citrulline is not itself the immediate starting material used to make nitric oxide.
- Vitamin C (as Calcium Ascorbate): Contributes antioxidant activity by donating electrons and supports enzymes needed for normal collagen formation. Collagen provides connective-tissue structure, including within blood-vessel walls. The modest amount here complements the amino acids; it does not replace dietary vitamin C.
Arginine-Citrulline Sustain 120t Is Formulated For
- Adults seeking a targeted arginine-and-citrulline combination for normal vascular signaling.
- Adults who prefer tablets with equal amounts of the two amino acids.

Additional ingredient cautions: Oral arginine can cause nausea, abdominal pain, diarrhea, bloating, gout, headache, allergic reactions, or airway inflammation and worsening asthma. Avoid arginine after a recent heart attack. Use caution with allergies or asthma. Arginine can interact with anticoagulant or antiplatelet medicines, herbs, and supplements, increasing bleeding risk; blood-pressure medicines, herbs, and supplements, nitrates, isoproterenol, or sildenafil, increasing low-blood-pressure risk; and diabetes medicines, herbs, and supplements, affecting blood sugar. Do not combine arginine with potassium-sparing diuretics such as amiloride, spironolactone, or triamterene because of high-potassium risk. Have your clinician review these combinations before use.
Frequently Asked Questions About Arginine-Citrulline Sustain 120t
What are the benefits of Arginine-Citrulline Sustain 120t?
Arginine-Citrulline Sustain combines two amino acids involved in the body's nitric oxide pathway with a small amount of vitamin C. Nitric oxide helps blood vessels relax as part of normal circulation. Arginine supplies a starting material, while citrulline contributes to the body's arginine supply. Vitamin C adds antioxidant and collagen-supporting functions. Each two-tablet serving contains 500 mg of each amino acid and 10 mg of vitamin C in a sustained-release tablet formula.
Who should take Arginine-Citrulline Sustain 120t?
This Jarrow Formulas product is intended for adults considering a targeted amino acid supplement for normal cardiovascular function. It suits someone looking for equal amounts of arginine and citrulline in tablets rather than a powder. The label directs adults to take 2 tablets 1-2 times a day on an empty stomach prior to meals, or as directed by a qualified healthcare professional. Pregnancy, nursing, medication use, medical conditions, and use under age 18 require professional guidance before starting.
Are there any side effects of taking Arginine-Citrulline Sustain 120t?
Arginine can cause digestive upset, bloating, headache, gout, allergic reactions, or worsening asthma. WARNING: Consult a healthcare professional before using this product if you are pregnant, nursing, under the age of 18, are taking medication or have a medical condition (especially of blood pressure or herpes); if adverse reactions occur, discontinue use. KEEP OUT OF THE REACH OF CHILDREN. Do not use if safety seal is damaged or missing. Avoid after a recent heart attack, and review the medication interactions and additional ingredient cautions above with your clinician.
How does Arginine-Citrulline Sustain 120t support overall health?
The formula focuses on a specific part of normal cardiovascular physiology: producing nitric oxide for cell signaling and blood-vessel relaxation. Arginine is used directly in that pathway, whereas citrulline is converted into arginine. Vitamin C contributes a separate antioxidant role and helps the body form collagen for connective tissues. These are nutritional functions, not a substitute for medical care or balanced meals. The sustained-release format describes the tablets, without guaranteeing a particular change in circulation or physical performance.
