NOW Foods L-Citrulline Pure Powder 4 oz

NOW® L-Citrulline Pure Powder supplies free-form L-citrulline with no fillers, letting you customize your serving. Citrulline is a non-essential amino acid and an important intermediate in the urea cycle, and one of its most notable features is that the body efficiently converts it into L-arginine — often raising arginine levels even more effectively than taking arginine directly. Through this route it supports the nitric-oxide pathway for healthy circulation and blood flow to working muscles, while also supporting healthy immune function.*

About the key ingredients

• L-Citrulline (free-form): An amino acid the body efficiently converts into arginine, supporting the nitric-oxide pathway for circulation and healthy immune function.*

Who it's for

NOW® L-Citrulline Pure Powder is well suited to athletes and active adults who want adjustable, longer-lasting circulation and performance support, and who prefer a filler-free powder they can dose to their goals. It appeals to those who found plain arginine short-lived, and to anyone focused on blood flow, nutrient delivery to muscles and immune health. It's commonly mixed into water before workouts.*

Cautions & interactions

As with any supplement, talk to your doctor before adding this product to your routine if you are pregnant or nursing, taking prescription medication, or managing a health condition. Keep it out of reach of children, store in a cool, dry place, and don't exceed the recommended serving. If you take a multivitamin or several supplements, review the combined amounts with your healthcare provider so you don't unintentionally double up on the same nutrient. Because citrulline supports the nitric-oxide pathway, check with your doctor before use if you take blood-pressure medication or are scheduled for surgery.
