L-Citrulline Powder 4 oz by Now Foods – Protein Metabolism Support Amino Acid Powder
L-Citrulline powder by Now Foods is a single-ingredient amino acid supplement in a 4 oz container. Its pure powder format supplies 1,500 mg of L-Citrulline per serving, with no other ingredients listed on the manufacturer's label.
This amino acid supplement focuses on citrulline rather than combining several nutrients in a blend. Citrulline participates in the body's handling of nitrogen from dietary protein and serves as a starting material for making arginine. The powder suits adults who prefer a measured teaspoon serving instead of capsules and want to identify exactly which amino acid they are adding to their routine.
Key L-Citrulline Powder 4 oz Benefits
- Supports normal protein metabolism through citrulline's role in processing nitrogen left over when the body breaks down amino acids.
- Participates in the urea cycle, the pathway that converts ammonia into urea for removal through urine.
- Provides an arginine precursor, helping supply the amino acid the body uses for normal nitric oxide signaling.
How L-Citrulline Powder 4 oz Works
Protein breakdown creates nitrogen-containing waste that the body needs to process. Citrulline is an intermediate in the urea cycle, meaning it participates in a sequence of steps rather than working as a standalone cleanser. This role connects citrulline to normal amino acid metabolism; it does not make the powder a substitute for dietary protein or a balanced intake of essential amino acids.
Citrulline also connects to nitric oxide production through its conversion to arginine, particularly in the kidneys. Nitric oxide is a signaling molecule involved in normal blood-vessel relaxation. Supplying a precursor is different from taking nitric oxide itself.
Key Functional Ingredients Include:
- L-Citrulline: Supports normal nitrogen handling as part of the urea cycle and supplies material for arginine production. Arginine, in turn, is used to make nitric oxide for normal blood-vessel signaling. These connected roles explain citrulline's place in amino acid nutrition without making it a complete protein source.
L-Citrulline Powder 4 oz Is Formulated For
- Adults seeking a single-ingredient powder for targeted citrulline supplementation rather than a multi-ingredient formula.
- Adults who prefer measuring a powder between meals and can follow the label's teaspoon directions.
- People choosing a vegetarian/vegan amino acid product with no other ingredients listed.

Frequently Asked Questions About L-Citrulline Powder 4 oz
What are the benefits of L-Citrulline Powder 4 oz?
L-Citrulline Powder 4 oz supplies 1,500 mg of citrulline per serving to support normal amino acid metabolism. Citrulline participates in the urea cycle, which helps the body handle nitrogen waste from protein breakdown. It also serves as a precursor to arginine, an amino acid used in normal nitric oxide signaling. This NOW formula contains citrulline without other ingredients, making it a focused option rather than a complete protein powder or multi-nutrient blend.
Who should take L-Citrulline Powder 4 oz?
This product is intended for adults who want a single-ingredient citrulline powder and prefer a teaspoon serving to capsules. The label describes it as vegetarian/vegan and directs use between meals. It is not a children's supplement. Anyone who is pregnant or nursing, takes medication, or has a medical condition should consult a physician before use, particularly people taking blood pressure medicines, nitrates, or other vasodilating drugs, or those with abnormal blood pressure.
Are there any side effects of taking L-Citrulline Powder 4 oz?
Citrulline's connection to arginine and nitric oxide makes medication review important. Caution: For adults only. Consult physician if pregnant/nursing, taking medication (especially blood pressure medications and nitrates or other vasodilating drugs), or have a medical condition (especially abnormal blood pressure). Keep out of reach of children. Do Not Eat Freshness Packet Enclosed. Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens. Long-term suitability should be assessed individually rather than assumed from the single-ingredient formula.
How does L-Citrulline Powder 4 oz support overall health?
Citrulline contributes to normal nitrogen processing and provides a route for the body to make arginine. These roles connect this powder to everyday amino acid metabolism and normal nitric oxide signaling, rather than to supplying all the building blocks found in a complete protein. The label's serving is approximately 1.5 g of powder, with 75 servings per container. Use the stated directions between meals while maintaining a varied diet; more citrulline is not automatically a better nutritional choice.
